This is an excellent circuit, it is nice and simple ! Thank you for giving the component value of the resistor, part number of the MOSFET, etc. Keep up the good work !
@@biohazardmadness1155 I don't know, but I guess a diode with PIV higher than 500v needs to be used. A 1N4005 has a PIV of 600v, but that may not provide enough protection, so a 1N4007, with a PIV of 1000v would be a good place to start! (BTW, PIV is peak inverse voltage).
First technical video Ive seen that, within 2 minutes, I realized I had not questioned anything I had just watched! Your videos are very thorough and to the point, provide a quick study, and you are very pleasant to listen to. I subscribed within 2 minutes! Keep this up and you'll reach the entire network!
Thanks for the tut.. Awesome now have a circuit to run the heater in the 2C39A uWave valve i am going to use in a 1.2GHZ tx tripler I am building. My wife said the valve in its mount looks like the robot from "Lost in Space".. Good enough reason to build it... 500VDC, tick, the rest is down hill, thanks a bunch, great work..
Soooo concise, simple, clear! You are finally number one. Subscribed! Thumb up! I'm sure you can and will make a video on mini Voltage display with 7-segments display, WITHOUT programming or Arduino, using common integrated circuits. Thanks.
Hey man, thanks for making these videos. They are very educational. I have been watching your them for a while now, and really you are what got me into hobby electronics. Also, your english is getting much better! (no offence)
Thank you for making a video about this with an actual explanation unlike so many others! Does transformer ratio determine step up as turns ratio or does it depend on mosfet on/off frequency? What component needs to be added to change that frequency?
This circuit is known as a "Flyback Transformer" It works but without significant filtering the voltage on the output will have lots of spikes. You will need a RC and a LC filter possibly 2 of each to get the ripple down if you plan to use this circuit in music.
It would be useful for us if you explained how you arrived at the conclusion that they coil & mosfet can only handle the limits that you described in the video. It would also be beneficial if you used the datasheet for the mosfet & showed your calculations. Thanks for sharing. Very nicely done vid!
I am loving the positive comments here... :-) 1. Can i replace the 180 Ohm resistor with a varriable resistor or potential-meter so i can varry the output? 2. What can i improve on the circuit to be able to use it as a booster for my solar pannel outputting 17 volts.
I see that the circuit is similar to the "Joule Thief" circuit. If so, you might need a "negative voltage clip" diode at the gate of the mosfet or the huge negative voltage bursts can fry it!
Hi, you have very good channel so thank you for all your videos. Quick question: I made this kind of voltage booster using small pcb transformer. I simply wired new primary coil and used old mosfet. My resistor is 100ohm. For the output, I use "secondary" side of that pcb transformer and I have connected it to a rectifier and therefore I have full DC output. When I charge a capacitor, it goes up to 220VDC. My input power is from adjustable lab power with 4.00VDC and roughly 150mA. If I try to adjust it to higher voltage 5VDC, amps go up to 3-4A and it won't charge my load capacitor. Can you explain what is causing that? Why can't I use higher voltage for higher output? If I turn it down to 4VDC, amps go down and the output voltage is back to normal.
disposable fuji flash camera works well for that, then add another ultra fast diode to charge two capacitors in series, doubling the output to around 800V
This works for me but can't power anything with a winding like a motor for example. I had a couple high voltage 40volt led lights that it powers no problem. I see store bought boost converters that run motors, what am I missing? What can I add to the circuit so I don't lose all my amperage?
An excellent adaptation of the blocking oscillator/ joule thief circuit! Appreciate the novel used of the CFL boost inductor to make a flyback! One query- in your initial test you don't have any load or bleeder resistor at the output. Where is the power being dissipated? Is the operation different during the no load?
Can we use any other transistor such as tip 41c or tip 42c for this inverter?I want to attach a voltage multiplier circuit to this inverter.Please recommend me the right capacitor values. I will be thankful to you.
Hi man, thanks a lot for this circuit, Is what I need for my personal DIY coil gun. My First question is: can I use as input an AA battery of 1.5v for an output of 450v DC, to charge a capacitor of 450v? Second question: is it possible to buy only an inductor of 30mH (as I can see from the label)? I can't find it on line, someone can post a link where I can buy it? Bye
These kind of people are taking a random mini inductor from a fluorescent lamp ????????????!!! are you serious guys???? Did he know what is for and what does it do in the lamp?? so that to give you this kind of voltage?? please be serious.
in first i read comments and see de video ,i see that your followers are saying good things about you , i'm gonna subscribe ,hope you keep your motivation and your seriousity , keep it up plz ,and thank you
How many turns is on the secondary coil? I am thinking to use a toroid ferrite core to wind because I may not be able to get the exact transformer you have.
For this video an your other one like this, you should discuss the winding resistance or number of turns on the indutor(secondary).

Finally someone who is speaking in a "tutorial". So sick of the music only videos.
Vraiment!
Thanks for your vids. Simple circuits, good explanation. I like them.
Very very good job my friend 👍
That was a awesome video! This is perfect for a high voltage project from which I use a AA battery for a coil gun

Very nice tip! Finding parts in waste light bulb. Very smart idea.
very informative to understand basic transformers and how they work, thank you. thumbs up
Highly educative. Thanks for this.
I like the new intro, good job
Nice and simple design for 3v to HV booster
It's a nice circuit I've built this before with a BJT but I'd never tried it with a MOSFET. I'm really excited to build this.
Hey, very well explained. I've liked it very much, learned a lot! Thank you!
Honestly, these videos are so good

you need 12v zener, because no matter the polarity mosfet gates and inductors dont mix well
Put a scheme or circuit
You changed my life sir! You will hear from me one day! Haha
muchisimas gracias lo voy a intentar hacer en mi casa para unos proyectos, sigue asi, gracias
Thanks Ludic!
Awesome work
Simply awesome
100 working. Thanks for your help.
Nice
instead of disassemble the fluorescent light, is there a part number available for the coil?
Hi Ludic I really enjoy your meticulous explanations. What country are you from ?
Hello Sir
This circuit produces spikes I have simulated it then how it produces AC as u said?
thanks

Great, I will try it.
Did it work?
Well i get it sir. If we install a thick coil in the secondary with 5 turns so will it give high ampere with a bit low voltage. Please reply. Thankyou
this video is about reusing HV coil. you can use this driver to drive any transformer
Great video! What would need to be adapted to be able to supply more than 2W? Say 100W?
disposable fuji flash camera works well for that, then add another ultra fast diode to charge two capacitors in series, doubling the output to around 800V
Thank you so much

with a load you have a voltage drop depending on the load itself
Best.detail and good
thankyou for clear explain this video
How did you determine which is negative and positive output from the bottom coils? Where do you run the output from?
great job 👍👍 ,Thank you
it would be great if you showed how you made that VOLTAGE DOUBLER at the end of this video as well
Hi, why is the plus vire going into the cool, would IT work without IT being in the coil?
What is the practical use for this type of voltage amplification ? trying to learn here !
Which cap and divide you use to multiple current 500 v to 1000 v ?
@Ludic Science can we use normal electrical tape to isolate the two winding of ferrite transformer?
Thanks for your vids

if i want to get AC, do i still need a resistor? does the resistor changes the frequency ?
is there transformer can be connected to function generator and step up the voltage to 1 kv at frequency 1khz??
can these be use to supply current to the building that has 90 volt and needs up to 220 volt ?
What i can do if i neet more current at the output of the circuit. Can i sustitud the mostfet forma 2n3055 transistor? Thanks
Isn't IRFZ44 an N-channel Mosfet? You've used the symbol of a P-channel in the schematic.
+Lucas Falcon you're right! My mistake
People who make videos like this DO NOT EVEN KNOW the correct symbols of electronics ...!
That's because judging people like you never give "people who make videos like this" a chance to correct themselves.

Do you?
what is the practical difference between this booster and zvs?
Super explanation
Really nice! :)
Sir,
I have 12volt but not any ampere.i want to make ampere in this but voltage should not be decreased. How can I make ampere in it??
Please help
This is basically a Bifilar Coil. You could have gotten an even higher output if you found the resonant frequency of the center-tapped inductor.
in first i read comments and see de video ,i see that your followers are saying good things about you , i'm gonna subscribe ,hope you keep your motivation and your seriousity , keep it up plz ,and thank you
Mind if i ask men.... but what is the formula on getting the voltage limit of the inductor coil...?
I didn't know that tree was a voltage but now I do thanks
nice tutorial thanx
can it be used to power up a motor in order to make a self sustained generator?
How many turns is on the secondary coil? I am thinking to use a toroid ferrite core to wind because I may not be able to get the exact transformer you have.
Right side how much turn?
Left 10 and 6.
What is the Right turn?
Thank you.
thank you
Hello bro,which supply you had given either dc or ac
For this video an your other one like this, you should discuss the winding resistance or number of turns on the indutor(secondary). Or even a inductance measurement just to give people a better idea of what to look for when choosing an inductor or transformer. How many windings do you think is on that secondary output coil?
Right 500÷3=166x10(primary)=±1660 turns
I'm guessing you will have about 30-50 Ohms of winding resistance.
I assume this could be used to charge a capacitor? Am I wrong? Need some way to charge a high voltage capacitor? I originally was gonna try a boost converter
I think this is similar to slayer exciter circuit, except the base connected to primary
Oh, I see that you speak english too. Congratulations !!!
Can I use tip31c npn transistor, or the CFL bulb transistor
can you tell me how much ampere should the inductor be of?
