A friend gave me some random stuff a while back and in it was one of those little high frequency transformers. It had a center tapped bifilar primary so when I saw it had a decent arc from feeding half of the primary a square wave I tried just wiring it up as a blocking oscillator and it gave me an amazing arc from something around 5 watts. It was surprising similar input and output compared to what I got using the frequency and on time I ended up liking the most from the square wave generator so it must have been a fairly low duty cycle still able to output the burning plasma. The arc was way longer than it should have been, something close to an inch and I was going to make a battery arc lighter from it but stuuuuupidly tried 'potting' it with gorilla wood glue and it ruined the secondary. Similar transformers I pulled from LCD monitors wouldn't perform the same. Been trying to get into flybacks again recently and I always think of that little transformer.. tape was gone too along with the part number.

How many watts, volts, amps is your TC? your frequency? what roll does the inductor play in the circuit? There is so much that goes into properly calculating all these factors. Try this website to figure out what you need for your configuration. www.classictesla.com/java/javatc/javatc.html
@@Zenodilodon @Zenodilodon 10 amps at 12 volts i want to find the right inductor for the ZVS for the best output power on the secondary by the way the secondary is a 500 turn coil with 28 AWG i am scared to fry my driver or coil by being stupid thanks for the link m8 :D
@@anekdoche7055 You're scared to fry stuff? Mate, you're making a device that fries stuff lol. You're probably going to need something of decent size and speed. Let me give you some tips on how to figure out what will work. The wattage you will need is around 120W, consider the size of the magnetic components needed to move that kind of power ( IE the small transformer in a 5v1A phone charger VS the transfo'rmer in a laptop PSU ) This will give you insight on what magnetic mass you need. Note that most ferrite cores will work as long as they are not for filtering purposes and will eat your power and got hotter/have slow response. You will want to skirt as close to the minimum core size needed as the TC itself is an air gap core that typically has a much faster frequency than the response of magnetic materials. You will want to wrap decently thick wire around your core, I'd say 2mm width of EM wire would do and you'd probably find a good spot between 10-20 turns. I hope that helps you grasp a bit more what your options are, how they work together, and how to select/make your needed inductors for this and future projects.
Can you do a deep dive into the plasma candle circuit ? I can’t find anything close to adequate regarding this topic .? Fantastic work on this one by the way 🙏
The trick with make a plasma candle is that it must be very fast, into the Ghz range and quite powerful. These are often done with large vacuum tubes and isn't something I have any experience with. Tested2Destruction might be able to help.
I also see a video on 'join the technicians channel about pocket soldering iron (SOLDER HERO MARK), I want to know more about that and how did you make that handle . IT WAS REALLY COOL 😍
More videos will be coming we both have hit a really busy streak as of late, but I wanted to get something up that might help others with some of the other projects on JTT. I need to make a solder hero as well eventually :P
Sir this was an excellent video explaining all the underestimated facts , but the problem of dying mosfets still persists and if you have provided the circuit for the part where h use only one coil for primary it would be very beneficial.....
I just learned of that style which uses a regular transformer in conjunction with a center tapped inductor or pair of matched inductors. When I get better with that style I plan on doing an update video on the ZVS stuff. If you need/want a diagram showing how to make that kind I can send it to you through e-mail. Send me an e-mail requesting the diagram. Zenodilodon@gmail.com
Very useful video thanks for that. Could you make another video explaining how to build that full bridge configuration transformer driver with coupling cap that u showed on video??
A video on full bridge circuits is in the future, that particular board that I used in the video is a prototype though and has some minor issues. It's based off the SG3525 IC which is analogous to the TL494 and is a dual output IC. We used a totem to drive the P channel mosfets. The issue with the current configuration is in the phasing between the 2 sides and thus the mosfets get hot since there it not a solid off during the 0 crossing.
I don't recommend putting mosfets in parallel, this can mess with things and I have has situations where instead of starting the osculation it turns on on both sides a bit more and cooks mosfets. I would just step up to using a larger mosfet instead for this application.
I watched all the video and you explain everything, but I don't understand how did you connect the zvs driver to the tesla primary and secondary (the tesla pen)
Same as any transformer in the video. You have a primary with 3 legs on for each mosfet out and then the center tap for ground. For use like a plasma pen any high voltage ZVS will do the same thing if you ground yourself placing the " closest wire to primary " of your secondary coil to yourself acting as a ground and then placing a sharp tip on the furthest secondary output. Please also not the pen is NOT a tesla coil, it uses a rewound CCFL inverter transformer. It's just a high voltage transformer and ZVS crammed into a little tube.
Running tesla coils of ZVS can get tricky as they often don't have much magnetic if any for proper ringing on a ZVS, other options like spark gap or other transistor set ups will be better for running an open air core transformer like a traditional tesla coil, The ZVS works great for magnetic transformers.
Did you figure out the differences and find a working solution for a tesla coil? You can also try to play with magnetic transformers more on ZVS. There are Tesla coils that use ZVS + high voltage transformer to charge a capacitor bank for a decent sized spark gap tesla coil. Also did you find the other video I spoke of on Join The Technicians?
Zenodilodon I see the video of the plasma pen one year ago I put a comment on it, it is awesome tutorial but I wanna make the tesla magic marker and after the plasma pen
It's coming, it's a simple n2222 slayer, not much special really. I want to try to make a better set up before I tackle it because I would love to see a little more power out of it, aside from that it's as it is now not much special. Video work is not my forte, it's slow and a side task for me but as I said, it's all coming and more.
Tak naprawdę nigdy nie było schematu pióra plazmowego, ponieważ był to projekt darmowej budowy. Mój przyjaciel też je zrobił i razem zamieściliśmy tutaj, jak zrobić wideo. th-cam.com/video/My_J3xzDaZ0/w-d-xo.html
Plasma pen was nice work. And I myself wanted to create one, so I made ZVS circuit as shown in your video of plasma pen then I tested it using LEDs as shown in this video , it worked fine but when I connected it to transform then there was literally no output voltage not even small voltage, I think my transformer was also fine as when I connected it with 9V battery then at time of conncting it to battery current jump up and goes down on disconnecting so it had shown a small voltage output just with battery, so transformer was fine. But I think switching was not occuring when I connect ZVS to transformer or may be another problem. Can you tell me a way to fix this issue?
Your inductor is probably the cause. There have been situations where I have tried inductors at random and it makes the circuit not work at all. It's about the only thing I can think of that would prevent it from working correctly. Also what voltage are you using for input and what resistors are you using for the gate pull ups?
@@maniksingh4119 Your resistors should be good. I cannot simply tell you what inductor to use as that all depends on your transformer and configuration. Pairing a transformer and inductor is one of the harder things to do and it can be a bit of trial by fire.
Sir, I had tested circuit with 5-6 inductors but none had produced output, are you sure that it is problem of inductor and you had mentioned inductor in description maybe 4r0 inductor something what does that mean? Please guide me
watched your video! very informative! could you point me to where i could calculate this stuff, or at least what things i should try to search. thanks!
That's the largest problem for ZVS stuff for most people is the calculations. It's not exactly straight forward. It's similar to an LC oscillator circuit in that you have inductance and capacitance in the equation however due to there being 2 magnetic components the inductor and transformer it becomes much more tricky to get the optimal balance. This is why I went through so many different set ups and included both success and failures to show physical correlation and effects of changing parts out. You can try to use JavaTC to do your LC maths quite a bit but it's still a tricky task. Even after a few years of messing around with this stuff it still can be hit or miss with how well something works. I do have planned for 2021 an update on some things I have learned since this video so check back for that every once and a while.
@@Zenodilodon Thanks man! I sure will! I am also planning on laying with this stuff. I know how oscillating circuits work, so i think i will just have to do some good old-fashioned research on this.
hello I love your guys videos and got inspired to make something like the plasma pen from your videos. I have all the parts but am having issues with it. a couple days ago I got the circuit running nice and it was throwing about 1 inch arcs running about 2.4amps@9.6v off a homemade zvs but the circuit suddenly stopped working while it was running and started drawing alot more amps and the arcs were gone. long story short I changed every single part on the circuit including 3 different sets of mosfets. and still same thing except I realized that there was actually output on the secondary but I had to short circuit it to get an arc and could only draw the arc out like a mm. while still pulling 3 amps from my batteries. and when I tried making a different inductor with a screwdriver the current dropped to around only 2 amps but still the same size arcs. do you know why this is happening? thank you
Glad to hear you enjoy the content. It sounds like your secondary has failed in an area and this is causing the draw of current and lack of output power. It sounds exactly what happens when we had breakdowns in our secondaries. A good way to manage this is to write the resistance of the secondary down. If that drops lower then you know it's done. There is also another way of doing ZVS which has a center tapped inductor, or 2 inductors of equal size attached to how the transformer is attached in this video. Than you just put a 2 wire primary transformer on the 2 outer taps of the inductor/s It works amazingly well. If you e-mail me I can send you pictures of how this is put together.
@ about 5:30 - Should you have said "Negative at source PULLS DOWN the other fet and turns it off"? I'm completely thrown off by you saying a negative current flows against the cathode of a diode. I'm super new to this hobby so I may be missing something obvious but I don't get the negative current flowing reverse bias THROUGH a diode. Maybe electrons flowing through that way? Or most likely just could have misunderstood.
The negative current flows through the Mosfet that is in the conducting state and through the diode back to the other Mosfet gate turning it off until the next cycle of phase shift in the magnetic components of the circuit. Both Mosfets have a pull up from the resistors and will want to be on at the same time without the diodes to ensure only one Mosfet is on at a time. Self oscillating circuits are a very tricky thing to learn because they are so dependent on the physical parameters of operation that can be quite hard to translate without a litany of demonstration, hence the long video provided to hopefully help provide enough piece for anyone to get enough comprehension to learn a practical working model in the best method for all.
@@Zenodilodon So let me tell you where this has me all F*$#ed up. I'm certain you know the way a full bridge rectifier works so lets use that example. On the negative end the voltage/current is not able to flow reverse bias through one diode and then flows up into the positive/live side forward bias through the other negative connected diode. So when you say there is current flow reverse through that diode I'm thinking there is some huge details I missed along the way.. is that current just the rated reverse leakage? I don't look at negative voltage as ground either, I look at it just as an upside down "positive" voltage that travels the other direction..... but I don't think I've ever heard of it flowing reverse bias through a diode. Again, maybe I'm just misunderstanding... But If I'm missing something I want to stop and take the time to learn it correctly.
Hi... just a quick question..... when connecting the zvs driver to a coil, is it OK to keep the LEDs connected as a visual indicator of status??? Awesome channel BTW
Yes you can keep the LEDs connected, keep in mind that when the transformer is connected that you may have to handle both higher input voltages and ring up on the transformer's primary so I would advise using suitable resistors in series with the LEDs and consider using 3-5 volt zener diodes to protect them. Thanks for the complement and good luck on building your ZVS!
@@marionlukebordios8963 Honestly a good day is anything under 75% lol. it's how you learn and get better. Year of making things that do nothing or make smoke.
Any schottky or signal diode with the appropriate voltage rating will work. This is not a very important thing to consider and doesn't have to be exact, most diodes will work.
@@Zenodilodon so please let me ask more. I use mosfet p75n02 smd. input port G = R470ohm. and use zener diode 4.5 or 4.6 vol. is the 5v input port working properly? thank you so much
@@duongbui9621 There is significant ring up on these circuits, figure it can go up 4x when made properly. I typically use ZDs that are 15-19v as many mosfets have a gate voltage of 25v. This cuts down how much current ends up being dumped in the ZD and helps to maintain oscillation. I'd say using a 4.6v ZD is too low for this application.
@@Zenodilodon i want to make a pulse welding machine from zvs circuit. so, I have to use DZs 15-19v, right? and how much voltage the mosfet port will work. Sorry for not having enough knowledge in this field. Could you please help me
@@duongbui9621 Your ZDs must be chosen to closely match the gate voltage of your mosfets. Check on the data sheet for the mosfets you bought for the gate voltage and choose a ZD that is about -3 volts from that rating and you should be fine. If you are intending to use a higher voltage select a ZD that has a decent wattage rating for larger applications.
You say the negative voltage flows from the source to the drain... does the mosfet not show a flow from drain to source/ground for a low side npn? I've stopped watching until this is clear to me. I'm thrown off by saying a negative voltage flowing reverse through the source and through the zener.... maybe if you said electrons I wouldn't be so confused right now... what am I missing? (Btw I would have been stoked if you cut the whole face interview and just discussed all that with a bench view... only preference though since I watch so many videos like this.)
In real physics yes electrons flow from the negative to the positive, this is how I speak because it's applicable to other fields of understanding and models. The electrons in this circuit flow from negative into the source through the junction and exit the drain. Zener diodes are only used for gate protection and do NOT conduct until they reach threshold voltage. I also try to speak of negative and ground in context as if they are applied in floating or grounded systems. Ground is not the same as negative. Refusing to watch the rest of an explanation video without an explanation, isn't that like holding yourself hostage for money kind of thinking?
@@Zenodilodon I get your analogy but everyone's situation is different right?. I'm 31 with a new hobby I've invested copious amounts of my savings into and you creators are my professors. If I misunderstand something in a video this long then I can't take in the proper remaining info. My kid just turned 4 years old. so since I first picked up a dmm when she was 2ish I've been limited to night time lab and study time. Since my career is unrelated, I try and use those nights as efficient as possible. That's why I held off watching at the moment... (I meant to delete this so I commented on my active channel I use for electronics.. feel free to delete this stuff and I'll do my response question to your other answer since I feel I asked my question a little more clear there. I'll give you a follow on both channels)
I will try to help out with answers, I am unsure how to format information at times my brain works very well with real time physics but trying to make a format style presentation or answer is nearly impossible for my head lol. In that sense I suck up information like collecting puzzle pieces hoping to eventually put them where they belong. This video is kind of like an attempt to dump out all the puzzle pieces on the topic I have collected. I myself just started getting into this power electronics stuff about 4 years ago in a more serious manor and it's still confuses me to a degree as well. I am by trade an optical/laser tech and have gone into this kind of stuff as hobby as well. Is your other channel Steering Electricity?
@@Zenodilodon Yes. Starting a channel with my couple hours a night is hard. My kids finally about the age where I can get a little free day time sometimes so I just went and bought a nice multi camera setup and editing laptop so I can start posting with some consistancy and less filming struggle. They won't get many views since I don't do social media anymore but I mainly want to make videos on things I struggle to find on here. Hopefully help just a couple people dedicated enough to scroll through pages of TH-cam searches down to my couple views. Filming lab projects is tedious and frustrating sometimes when you just want to focus on the project. So kudos for the "fuck it, just post it all" upload.
Sorry about that Well played. I wish I had a job but I'm happy staying home taking care of my lil girl and running various experiments and working as many side jobs ... any my ion drive with eight stage coil accelerators is coming along with lots of trial error and lots of reiterations because I know there's a better way to help put the thrust without adding 490 lb and only getting 3 times the amount of thrust when the original one was around 12 lb and output 92 million Newtons of thrust that's not bad now they just accelerate it with a multi-stage linear induction motor to accelerate the ions even faster Ergo more thrust im trying to do so all while remaining it under 20 lb trying to show NASA that you can get more thrust without making it 50 times heavier than the original ion drive that's on the dawn spacecraft right now so. any tips on how to get the most effective Corona with out the arc jumping across I was thinking about using an electromagnet to force spread the ark into more of a Corona what's your thoughts
I'm just saying NASA's MK3 Drive is a 500-pound slab of shit that's 17 x heavier than 3 MK1 drives that would have been just as effective and had the same amount of thrust if they had just used 3 MK1 drive so why spend like 7 to 18 years and probably a couple of million dollars on something that's less effective what the fuck
@@numatechprototypes222 Pulse your high voltage, you can get more power/voltage per distance in air and avoid break down discharge/arcs It needs to be fast. I would also suggest looking into slow moving ions and use those to increase repulsion effect. As far as Nasa goes, we already know they don't know that newer should mean better lol
If it helps, I don't have a job really either. I make it from project to project with a passion, but I have given up a great deal of stability to focus on learning and sharing content with others. I don't care if I die poor, but to heck if I am gong to die a nobody who makes little contribution to the world.

@@JotticunChapter2 I watch the messed up subtitles, they are funny sometimes. I have seen them also omit strange stuff, like " None sense " was removed. I was like but why? 16 times smaller? That's like the size of a piece of rice.

Glad you found this of good use!
@@Zenodilodon it was the lack of editing that made it work, my friend. Real time, no skipping or rushing past steps/fails. I've tried zvs drivers a few times and gave up, but you've put me on a new quest :) .. Cheers mate, much appreciated. Good to see you're still around too.
@@DirtyDazz-The_Original I know a few people who have said the same thing, it's not easy to understand so I used many different sized set ups to help other cross reference parts and their function. It's how I learn things best myself.

@@Zenodilodon hehe, good stuff mate. Make sure you keep sharing your experiences. I keep zapping myself with capacitors still holding charge, so I'm steering clear of high amp designs for the time being. I figure at least a12 month period of no shocks before I step up the game. Lol.

what inductor should i use for a tesla coil?
How many watts, volts, amps is your TC? your frequency? what roll does the inductor play in the circuit?
There is so much that goes into properly calculating all these factors. Try this website to figure out what you need for your configuration.

@@Zenodilodon @Zenodilodon 10 amps at 12 volts i want to find the right inductor for the ZVS for the best output power on the secondary by the way the secondary is a 500 turn coil with 28 AWG
i am scared to fry my driver or coil by being stupid
thanks for the link m8 :D
@@anekdoche7055 You're scared to fry stuff? Mate, you're making a device that fries stuff lol.
You're probably going to need something of decent size and speed. Let me give you some tips on how to figure out what will work.
The wattage you will need is around 120W, consider the size of the magnetic components needed to move that kind of power ( IE the small transformer in a 5v1A phone charger VS the transfo'rmer in a laptop PSU ) This will give you insight on what magnetic mass you need.
Note that most ferrite cores will work as long as they are not for filtering purposes and will eat your power and got hotter/have slow response.
You will want to skirt as close to the minimum core size needed as the TC itself is an air gap core that typically has a much faster frequency than the response of magnetic materials.
You will want to wrap decently thick wire around your core, I'd say 2mm width of EM wire would do and you'd probably find a good spot between 10-20 turns.
I hope that helps you grasp a bit more what your options are, how they work together, and how to select/make your needed inductors for this and future projects.
@@Zenodilodon thank you very much, i will look into it :P
Can you do a deep dive into the plasma candle circuit ? I can’t find anything close to adequate regarding this topic .? Fantastic work on this one by the way 🙏
The trick with make a plasma candle is that it must be very fast, into the Ghz range and quite powerful. These are often done with large vacuum tubes and isn't something I have any experience with. Tested2Destruction might be able to help.
Very good sharing👍
Bom dia toligadinho no canal paulista Pernambuco Brasil
I also see a video on 'join the technicians channel about pocket soldering iron (SOLDER HERO MARK), I want to know more about that and how did you make that handle . IT WAS REALLY COOL 😍
More videos will be coming we both have hit a really busy streak as of late, but I wanted to get something up that might help others with some of the other projects on JTT.
I need to make a solder hero as well eventually :P
Sir this was an excellent video explaining all the underestimated facts , but the problem of dying mosfets still persists and if you have provided the circuit for the part where h use only one coil for primary it would be very beneficial.....
I just learned of that style which uses a regular transformer in conjunction with a center tapped inductor or pair of matched inductors. When I get better with that style I plan on doing an update video on the ZVS stuff. If you need/want a diagram showing how to make that kind I can send it to you through e-mail. Send me an e-mail requesting the diagram. Zenodilodon@gmail.com
Awesome......
I just finished watching this whole 3 hour 5 second video 😂
That's a lot of dedication, holy heck lol
Very useful video thanks for that.
Could you make another video explaining how to build that full bridge configuration transformer driver with coupling cap that u showed on video??
A video on full bridge circuits is in the future, that particular board that I used in the video is a prototype though and has some minor issues. It's based off the SG3525 IC which is analogous to the TL494 and is a dual output IC. We used a totem to drive the P channel mosfets. The issue with the current configuration is in the phasing between the 2 sides and thus the mosfets get hot since there it not a solid off during the 0 crossing.
@@Zenodilodon since i don't have an oscilloscope I'm waiting for u to make an explicit diagram for that.good job bro keep it up
when paralleling mosfets, do you have any advice other than an extra resistor on the gate ? : )
I don't recommend putting mosfets in parallel, this can mess with things and I have has situations where instead of starting the osculation it turns on on both sides a bit more and cooks mosfets. I would just step up to using a larger mosfet instead for this application.
I watched all the video and you explain everything, but I don't understand how did you connect the zvs driver to the tesla primary and secondary (the tesla pen)
Same as any transformer in the video. You have a primary with 3 legs on for each mosfet out and then the center tap for ground. For use like a plasma pen any high voltage ZVS will do the same thing if you ground yourself placing the " closest wire to primary " of your secondary coil to yourself acting as a ground and then placing a sharp tip on the furthest secondary output. Please also not the pen is NOT a tesla coil, it uses a rewound CCFL inverter transformer. It's just a high voltage transformer and ZVS crammed into a little tube.
Running tesla coils of ZVS can get tricky as they often don't have much magnetic if any for proper ringing on a ZVS, other options like spark gap or other transistor set ups will be better for running an open air core transformer like a traditional tesla coil, The ZVS works great for magnetic transformers.
Did you figure out the differences and find a working solution for a tesla coil? You can also try to play with magnetic transformers more on ZVS. There are Tesla coils that use ZVS + high voltage transformer to charge a capacitor bank for a decent sized spark gap tesla coil.
Also did you find the other video I spoke of on Join The Technicians?
Zenodilodon I see the video of the plasma pen one year ago I put a comment on it, it is awesome tutorial but I wanna make the tesla magic marker and after the plasma pen
It's coming, it's a simple n2222 slayer, not much special really. I want to try to make a better set up before I tackle it because I would love to see a little more power out of it, aside from that it's as it is now not much special.
Video work is not my forte, it's slow and a side task for me but as I said, it's all coming and more.
do you have a link to that earlier plasma pen schematic?
Tak naprawdę nigdy nie było schematu pióra plazmowego, ponieważ był to projekt darmowej budowy. Mój przyjaciel też je zrobił i razem zamieściliśmy tutaj, jak zrobić wideo.

Plasma pen was nice work. And I myself wanted to create one, so I made ZVS circuit as shown in your video of plasma pen then I tested it using LEDs as shown in this video , it worked fine but when I connected it to transform then there was literally no output voltage not even small voltage, I think my transformer was also fine as when I connected it with 9V battery then at time of conncting it to battery current jump up and goes down on disconnecting so it had shown a small voltage output just with battery, so transformer was fine. But I think switching was not occuring when I connect ZVS to transformer or may be another problem. Can you tell me a way to fix this issue?
Your inductor is probably the cause. There have been situations where I have tried inductors at random and it makes the circuit not work at all. It's about the only thing I can think of that would prevent it from working correctly. Also what voltage are you using for input and what resistors are you using for the gate pull ups?
I am using 333 ohm resistors and 5-9V for input.
Which inductor I should use?
@@maniksingh4119 Your resistors should be good. I cannot simply tell you what inductor to use as that all depends on your transformer and configuration. Pairing a transformer and inductor is one of the harder things to do and it can be a bit of trial by fire.
Sir, I had tested circuit with 5-6 inductors but none had produced output, are you sure that it is problem of inductor and you had mentioned inductor in description maybe 4r0 inductor something what does that mean? Please guide me

watched your video! very informative! could you point me to where i could calculate this stuff, or at least what things i should try to search. thanks!
That's the largest problem for ZVS stuff for most people is the calculations. It's not exactly straight forward. It's similar to an LC oscillator circuit in that you have inductance and capacitance in the equation however due to there being 2 magnetic components the inductor and transformer it becomes much more tricky to get the optimal balance. This is why I went through so many different set ups and included both success and failures to show physical correlation and effects of changing parts out. You can try to use JavaTC to do your LC maths quite a bit but it's still a tricky task. Even after a few years of messing around with this stuff it still can be hit or miss with how well something works. I do have planned for 2021 an update on some things I have learned since this video so check back for that every once and a while.
@@Zenodilodon Thanks man! I sure will! I am also planning on laying with this stuff. I know how oscillating circuits work, so i think i will just have to do some good old-fashioned research on this.
hi sir it's really awesome and rich thanks a lot but if you use oscilloscope some time it will be so better and helpful
Bro you did not show a zvs without senter tap does anyone or you have link for it I really want it
Can I use tvs diodes in lieu of the zener diodes??
As long as the clamping range of the TVS diode is at or below the voltage of the gate input you should be able to use them to protect your mosfets
hello I love your guys videos and got inspired to make something like the plasma pen from your videos. I have all the parts but am having issues with it. a couple days ago I got the circuit running nice and it was throwing about 1 inch arcs running about 2.4amps@9.6v off a homemade zvs but the circuit suddenly stopped working while it was running and started drawing alot more amps and the arcs were gone. long story short I changed every single part on the circuit including 3 different sets of mosfets. and still same thing except I realized that there was actually output on the secondary but I had to short circuit it to get an arc and could only draw the arc out like a mm. while still pulling 3 amps from my batteries. and when I tried making a different inductor with a screwdriver the current dropped to around only 2 amps but still the same size arcs. do you know why this is happening? thank you
Glad to hear you enjoy the content. It sounds like your secondary has failed in an area and this is causing the draw of current and lack of output power. It sounds exactly what happens when we had breakdowns in our secondaries. A good way to manage this is to write the resistance of the secondary down. If that drops lower then you know it's done. There is also another way of doing ZVS which has a center tapped inductor, or 2 inductors of equal size attached to how the transformer is attached in this video. Than you just put a 2 wire primary transformer on the 2 outer taps of the inductor/s It works amazingly well. If you e-mail me I can send you pictures of how this is put together.
Alright can I get your email?

Thanks bro ❤
@ about 5:30 - Should you have said "Negative at source PULLS DOWN the other fet and turns it off"? I'm completely thrown off by you saying a negative current flows against the cathode of a diode. I'm super new to this hobby so I may be missing something obvious but I don't get the negative current flowing reverse bias THROUGH a diode. Maybe electrons flowing through that way? Or most likely just could have misunderstood.
The negative current flows through the Mosfet that is in the conducting state and through the diode back to the other Mosfet gate turning it off until the next cycle of phase shift in the magnetic components of the circuit. Both Mosfets have a pull up from the resistors and will want to be on at the same time without the diodes to ensure only one Mosfet is on at a time.
Self oscillating circuits are a very tricky thing to learn because they are so dependent on the physical parameters of operation that can be quite hard to translate without a litany of demonstration, hence the long video provided to hopefully help provide enough piece for anyone to get enough comprehension to learn a practical working model in the best method for all.
@@Zenodilodon So let me tell you where this has me all F*$#ed up. I'm certain you know the way a full bridge rectifier works so lets use that example. On the negative end the voltage/current is not able to flow reverse bias through one diode and then flows up into the positive/live side forward bias through the other negative connected diode. So when you say there is current flow reverse through that diode I'm thinking there is some huge details I missed along the way.. is that current just the rated reverse leakage? I don't look at negative voltage as ground either, I look at it just as an upside down "positive" voltage that travels the other direction..... but I don't think I've ever heard of it flowing reverse bias through a diode. Again, maybe I'm just misunderstanding... But If I'm missing something I want to stop and take the time to learn it correctly.

Hi... just a quick question..... when connecting the zvs driver to a coil, is it OK to keep the LEDs connected as a visual indicator of status??? Awesome channel BTW
Yes you can keep the LEDs connected, keep in mind that when the transformer is connected that you may have to handle both higher input voltages and ring up on the transformer's primary so I would advise using suitable resistors in series with the LEDs and consider using 3-5 volt zener diodes to protect them. Thanks for the complement and good luck on building your ZVS!

Can you say more accurately and more specifically about the diode you are using.thanks you
Any schottky or signal diode with the appropriate voltage rating will work. This is not a very important thing to consider and doesn't have to be exact, most diodes will work.
@@Zenodilodon so please let me ask more. I use mosfet p75n02 smd. input port G = R470ohm. and use zener diode 4.5 or 4.6 vol. is the 5v input port working properly? thank you so much
@@duongbui9621 There is significant ring up on these circuits, figure it can go up 4x when made properly. I typically use ZDs that are 15-19v as many mosfets have a gate voltage of 25v. This cuts down how much current ends up being dumped in the ZD and helps to maintain oscillation. I'd say using a 4.6v ZD is too low for this application.
@@Zenodilodon i want to make a pulse welding machine from zvs circuit. so, I have to use DZs 15-19v, right? and how much voltage the mosfet port will work. Sorry for not having enough knowledge in this field. Could you please help me
@@duongbui9621 Your ZDs must be chosen to closely match the gate voltage of your mosfets. Check on the data sheet for the mosfets you bought for the gate voltage and choose a ZD that is about -3 volts from that rating and you should be fine. If you are intending to use a higher voltage select a ZD that has a decent wattage rating for larger applications.
👽 grootings earthwoman! take us to ikea
lol, causing internet mischief again I see.
@@Zenodilodon 🤫🤫🤫🚀🚀🚀
You say the negative voltage flows from the source to the drain... does the mosfet not show a flow from drain to source/ground for a low side npn? I've stopped watching until this is clear to me. I'm thrown off by saying a negative voltage flowing reverse through the source and through the zener.... maybe if you said electrons I wouldn't be so confused right now... what am I missing? (Btw I would have been stoked if you cut the whole face interview and just discussed all that with a bench view... only preference though since I watch so many videos like this.)
In real physics yes electrons flow from the negative to the positive, this is how I speak because it's applicable to other fields of understanding and models.
The electrons in this circuit flow from negative into the source through the junction and exit the drain. Zener diodes are only used for gate protection and do NOT conduct until they reach threshold voltage.
I also try to speak of negative and ground in context as if they are applied in floating or grounded systems. Ground is not the same as negative.
Refusing to watch the rest of an explanation video without an explanation, isn't that like holding yourself hostage for money kind of thinking?
