- You should definitely buy one of these. I was genuinely surprised by how well it runs.
Thanks for watching!

Thanks from Russia. I use this ZVS also and bought it for 6 USD with free shipping.
I make one with less than 3 usd
@@endothermicexothermic4051 , I have no spare time for creating and constructing )))) Also I have a high-quality PCB )))
Mate, thank you very much for this video.
I wanted to buy this ZVS from ALI.... now I will!
I used one with 32V . The flyback transformer had an Center tab so 3 pins to connect . The interesting thing is that the transformer blew up before the mosfets did.
I got a ZVS from China for the same price and because I was the first buyer they even offered me a free flyback transformer!
I pushed my driver I got off amazon to 30V and a little more than a dozen amps, and the MOSFETS were basically fine, only warm. It’s incredible how we can build massive and super intricate circuits to drive fly backs, but there’s always an Asian who is better than you
With the -12v and 12v from a pc Power supply it Works great!!
Idk why your homemade zvs drivers blow up that often, i have never had that problem even when running on 42V input.
Failure to begin oscillation can cause a mosfet to be shorted. I had to increase a zener diode on one I built to begin proper oscillation
@@OtherDalfite i used mosfets that are way more powerfull than my power supply could provide so i never had issues with shorting as i could only give it 5A
I realize it's kind of off topic but do anybody know a good site to watch newly released tv shows online?
@Anthony Drew Lately I have been using Flixzone. Just search on google for it :)
@Anthony Drew i would suggest FlixZone. Just search on google for it =)
If you can get your hands on an old crt mini size the tiny flyback is far more terrifying than the regular size ones
It may be the inductor network you chose. Incorrectly sized inductors will result in blown fets. Also poorly designed caps is a massive ZVS downfall.
Odd how you've had such bad luck with homemade drivers, mine have always been very messy and I've never had one failure. I think you need a power supply with a fast rise time or else it makes the circuit latch up.
Components are much cheaper here in india
Resistor and diodes cost 1 to 5₹ and irfp260n costs 70₹ (1$~)
Hi tejas, can you tell me what diodes are used in the ZVS, i have to replace mine cuz the diodes got burnt
@@balajilakshminarayan1593 1n4007 is commonly used diode on zvs
@@lanzaxell4853 thanks a lot man !!!
@@balajilakshminarayan1593 or uf4007
yes cuz most components from Indian electronics shops are fake, if you buy a genuine irfp260 from lets say digikey it costs $4ish almost 300 rupees. these fake components is the main reason i import my stuff
Werry smart to do that in the carpet-place
Ive got the same board.. for more fun go with 5 turns.. mines doing 5 turns running off 20v
Whats the current draw from the low voltage power source? Also what do you use for your power source?
Hello i have the same zvs driver but mine was dead after like 1 minute of making sparks with a flyback. Can someone explain what killed my zvs driver? I made like 3 sparks and while driver was on (it was on but i was not making sparks at the moment) i saw a little blink and suddenly my driver was shorted. I powered it from 12V DC 50W power supply. I don't know what about the fets but diodes are dead. Can someone explain why it happened?
Thank you for sharing. Good video.
I used one of those flyback transformers from an old plasma ball, I wired up up, and I got tiny arcs, not even a millimeter.
Thank you for Sharing this information and demo. What is the Output Voltage of this ZVS Driver ?
On 12 volts it is about 15 KV, on 24 volts it's about 25 KV
I Meant just the ZVS Board (Not the output of the HV Flyback Transformer). Any idea of the Frequency of the Driving ZVS board ?
@@javiergonzales8487 the usually list it as variable between 30khz and 50khz. that might be the center tap ones only.
What else beside this board do i need, to make Sparks/an induction heater?
A power supply that supports the input
That's strange, I built plenty of ZVS drivers, even a 1kw one which I gave me huge 8 inch arcs from a flyback, and I've never popped a transistor yet.
Yeah! Clem we've seen you not blowing stuff up on your very entertaining videos bruv. 😎💕🖖
At about timestamp 0:40 you state two 47 Ohm resistors...did you mean 470 Ohm??
THANKS MUCH!!!
Building one is quite simple....I don't know about ur place..but in my country...I built the whole driver for only 3$ ...and it runs like a charm.😎
The MOSFETS are $3 each in the US and I tend to blow a lot of them, so it is easier for me to buy a working one. I am glad that your's are working!
you couldn't get the shipping for the parts here in the USA for $3.
Eli Z not china but from india.
crazy plasma 😖😖😖😖😖😖😖😖
Night mare in action....??????🤖
Hi i have the same zvs but nothing will be hot. The coil has the diameter of a 18650 battery, 10 windings, and the coil is alminium. The voltage is 20v and the ampere is 4a
Why it doesnt work? Thx?
LMAO!!!
Really dude you're arcing that transformer on the carpet??? I hope your home owners insurance is paid up. Lol
I’m going to try to push mine to 34 volts when it comes in
Funciona bien 👌 con el flyback
ok you got me hooked. I"ve been wanting to build a jacob's ladder for a while now, and this ZVS thing looks like its halfway there, you have that other module to make the spark, can you list that part as well? in other words, what are ALL the parts I need to order to repeat this video at home? thanks,. - J
You need the ZVS board, a flyback transformer (you can salvage one of these from anything that uses a CRT screen), and a 12 volt power source (I used a 12 volt battery). That's the works
Thanks cleveland for the response, I got my two parts, exactly the ones you have in this video. Can I trouble you for more details on what you are talking about at 1:34 about the "8 turn primary" ? did you add the red coil around that part? my flyback didn't come with those red wires wrapped around that bar/handle part of the flyback. Is it solid core or stranded wire? you also added the black wire to the end of it, why? I assume those wires connect to the the "output-a" and "output-b" terminals of the ZVS.
To make the spark, It is correct that you are bringing the end of wire that is from the suction cup to the pin that is its associated ground at the pins area of the flyback? In looking at other ZVS's I see other connections that use a center pull on the winding and the ZVS has three terminals. Can you explain the difference? I've also seen where people connect the zvs to 2 of the input pins at the bottom of the flyback, is there a reason you didn't use those instead of the winding?
thanks again for your video, I am really excited to put mine together safely and to understand what is going on here.
Sorry for the late reply!
-The 8 turn primary is 16 gauge solid core wire that I would around the core of the flyback
-I added the black wires at the end because they were thinner and would be easier to attach to the screw terminals in the driver board
-Connecting the ZVS output to the two internal pins on the flyback also works, but because the ZVS driver is so powerful, the flyback can internally short out if over-driven using the internal primary pins. That is why it is safer to wind your own primary
-Some ZVS drivers use a center tap, however this one was constructed in a way that does not require a center tap. It requires more components but it's just what the manufacturer chose to do
Hopefully this helps!
Whoo hoo1!!!! I got it working!!! thank you so much for your video and advice! I thrilled with the way it came out: th-cam.com/video/d9qPR-W_5wM/w-d-xo.html
Well guess what I don't want you blowing it up so submerge it in canola oil so it will dissipate the heat better and not blow up the mosfet like I did today I got humongous arcs from it just before the most blew up $11 down the drain
Is it possible to set frequency, such as 20 ~ 50 khz using that module? Is it possible to get feedback to monitor the output?
Thanks for this video. Is it possible to use this as an induction heater by just connecting a copper coil to it?
Saya pikir itu bisa dicoba
I got the same driver and my mosfets got pretty hot I don't know but I think around 60-70C
I got one of these, hooked it to a makita 18v 3ah battery and popped a couple things. I know nothing about electronics but still don’t know why it broke, specs for the battery tell me I didn’t overload it but again, idk anything
This circuit has no internal current limiting or protection, just like the battery. I think your battery broke because this device have drained much more than 3 amps. For a short time, a 3Ah battery can supply, let's say, 30 amps, but it's lifespan degrades drasticly.
3 Ah means that the 100% charged battery can safely supply 3 amps during 1 hour, and it will be fine. If the drained current is much greater - the battery will still try to supply it, in cost of it's own life.
It ships from China that will be a red flag you forgot the star
have you tried connecting the outputs directly to the flyback primary coil input pins instead of winding your own coil on the ferrite?
I have not with this model. When I have done it in the past, the flyback usually ends up internally shorting
the wires are too thin. the ZVS will melt them.
@@jontanneguy4960 yeah ive learnt alot in the last two years about chinese zvs drivers. Don't hook them up the the input pins of the flyback, the zvs doesn't like it lol. Induction heater drivers i found work really well to, just remove the copper coil and then wire the flyback like you have in the video. You get some chunky arcs
My mosfets blew up today on that zvs driver a similar one to it from China don't buy it I over drove it if I were you I wood submerged it in canola oil so it doesn't break I'm going to try that when I buy a new one
I have that same module and am using a 24vdc, 1000w, 20amp power supply. The coild is 12-guage solid copper wrapped 7 times. Set to 24vdc, I turn-on the power supply and in about 1 second, the coil gets so hot that the solder holding the terminal on the circuit board melts & the terminal falls off. Any idea of how to correct/fix this problem? Thanks!
lower your wire gauge like 15 to 20 and wound around 8-11 turns
I had one og of my transistors explode on me and it's like a firework lol
I ordered this! It states 1000W 20A. Does the 20A refer to the OUTPUT current? If so, ideally, it's 50V MAX at output? Is this a sine wave?
In my final app, I need "sinusoidal approx. 600vAC peak at 10A MAX" to drive a bridge rectifier. What do you suggest I add to this driver output?
THANKS FOR THE GREAT VIDEO!!!
The max *input* voltage = x4 of MOSFET max. Vds voltage. Yup, it's a 50v max for this PCB with 200v-rated IRFP260.
The *output* voltage depends on the transformer ratio, this one produces >10kV. Are you trying to build pure sine inverter or something?
@@arthasmenethil5752 Yes, High wattage with AC / DC outputs.
@@dalenassar9152 Yup, it has sort of a sine wave, but it's unusable for 50 hz UPS: the waveform distorts under the load and the frequency shifts like crazy (mine changes from 10 kHz up to 800 kHz) a HUGE iron drossels required for 50 hz, and I have no idea how TF it even possible to make this thing a 3-phase.
It’s cheaper, better and more reliable to use the EG8030 chip for 3-phase, or EG8010 for 1-phase (they have pre-installed firmware) + 3 IGBT half-bridges.
There are plenty of projects with arduino as well.
Yup, it require some power electronics knowledge, so be ready to burn some silicon during tests...
@@arthasmenethil5752 Yeah...just getting into that Hi-Freq power stuff.
I got a couple of those 12VDC 720W server supplies and got two isolated for 24v @ 50A. I saw a YT video by "Schematix" of a HUGE induction heater. He used a small PS that looked about the size of the server PS's, but put out WELL OVER 50v / 50A @ 3kW!!
@@dalenassar9152 The induction heating ain't care much about the stability of the frequency, waveform, and output voltage.
Even cheap chineze UPS are using the low voltage PWM push-pull + HV full bridge to form a sine wave.
If there were any method to apply a simple and cheap ZVS cirquit into UPS - trust me, the market would be full of em long time ago :)
What power supply to use for it? Any driver outputting 3-1kV?
I ran mine for 45 min on 59 volts by accident before it blew.
1:25 burning 🤣🤣🤣🤣
Why do the gate resistors draw large current??
Man, mine have 3 contacts, I bought it with flyback transformer which also have 3 contacts, and, I just connect those 3 contacts with zvs and that's that
i need one of those for aflyback, but it should stay working around an 1 hour /day.
Its better with a cooler? i dont want spend more than 15 $. This one would work for a long time?
it is ok for low voltage like 12v but 20-30 you better add a fan
I want use it for heating via induction .Can I use a longer coil to heat a metal pipe of about 25 cm?
Yes. Be careful heating large objects
what powersource do you use for this?
Link of ZVS flyback driver please greetings from jicaral puntarenas costa rica
47 or 470 ohm on the gates?
Will this work with a car ignition coil ?
can you charge a fan caps with this flyback driver?
Yes but you need to watch the output voltage and require a properly rated diode.
I guess you blew your MOSFETS because you used 47 ohm resistors and the circuit value is 470 Ohm and also the Pulldown is 10K not 5.8k

Ok you need to be careful with your language, at the end you said "I had no idea that thing would blow up like it did" - are you talking about the video or the amp? I'm not going to make it if it's gonna blow up
Hi, do you know if it would be possible to connect a heating coil directly to this board like it is on this one: i.ebayimg.com/images/g/cuAAAOSwXPNaCUsy/s-l1600.jpg
I'm not sure but it looks like the same design as most of the flyback drivers on eBay
Can I create those arcs with 30v 5A
Depends on the type of your PS. if it is a switched mode PS, unfortunately no. But if it is a simple linear power power supply, then you probably can.
can you touch the arc ?
Definitely do not touch the arc. It is a high current and can cause burns and even death
burn finger'
Lol
It's a high current high voltage power supply , touch it with yer toungue No! No! No! Do not touch the pretty arc it will kill you.😎💕🖖
I also build one
And my mosfets got also blown erverytime
Sory my english is not verry good
Speak Polish ?
Your English is fine,you should not apologize. I think the zero volt switch circuit is a sensitive circuit if everything is not right it will blow the fets every time. Check and recheck the circuit and components are correct values and good quality. 😎💕🖖
Thank you
Yes this circuit is a bit hard to get going. Its because of the Spikes and interruptions on the Startup. To Work reliably it would need some Kind of Filter and Stabilisation. Maybe i will redesign a propper Version With Power Regularien and safetey Features one day.
5000kV?
mine has irfp064n
I get it for 7€ from Amazon 😂
China does fantastic work, it all depends on the spec and budget the twats ordering the item choose, its always profit over value.
I first noticed it when i came across an isometric drawing of a pair of pants, everything from obviously materials, quality of stitching, how many threads, how many rows., thread thickness....
Cos to be honest the simple t shirt that was for sale 20yrs ago, the kind that last a decade vs 1 wash and its screwed that i find today is down to the greedy prick that orders the cheapest garbage design to maximize profit.
2 zvs driver and parallel the output to 1 coil for induction heater to combine the power is that gonna work?
nope, cause they won't work synchronous. Even paralleling FET's in a single ZVS cirquit will cause some troubles.
