Zvs flyback driver problems

I think its power supply related. I use IRFPn MOSFETs and used the same schematic you did but I power it with a Variac running through a full bridge rectifier to get the DC power I need and I have zero issues with heat, the only problem I have is the flyback arcing to itself and the voltage getting so high it arcs through wire jackets lol.

This circuit actually worked well for me the first time around when I placed the components on a breadboard, then it stopped working. I thought my connectins were sloppy so I etched a board and it still didn't work. However, this circuit was great while it was working. Reply 10 years ago on Introduction. Reply 6 years ago. Yes it will be : but I think you might want to add another one in series to increase voltage to obtain longer arcs, since the xbox psu is just 12v Makes nice induction heater needs some work for a smelter.

Share it with us! I Made It! Lazy Susan 2. You can power the ZVS driver above 36v, but then you risk blowing up your driver, check step 7 for instructions for modifying your ZVS driver to handle higher input voltages. You may hear an very high pitched squeal from your ZVS driver, don't worry, that is normal. What ever you use as your negative terminal, it will get hot, very hot! The arc will melt any thin wire you use into little metal balls and steal will just fly everywhere, which is cool and dangerous!

If anyone has a good explnation why the negative terminal get so hot and the positive terminal remains fairly cool, I'd like to know.. This is because when the arc got inside the bulb, the gas inside heats up, causing it to expand and escaping through the hole thus creating a "plasma thrower". I have not tried this yet, but there is a revision of the ZVS driver by Andrinerii.

The fun does not stop there, if you are hungry for more bigger, hotter, and beastly arcs, a few changes to your ZVS driver should be made to handle higher input voltages. Change the 12v zenner diode to 15v zenner diode. Increase the number of windings on your flyback transformer. Increase the value of the inductor. I heard that some people had operated their ZVS driver at voltages over , just imagine how massive their arcs must be!

Also, this ZVS driver circuit does not have be used just for the flyback transformer, you can replace it for use a different transformer to charge up your large capacitor banks for coilguns, railguns, etc. It might be even possible to do induction heating with this ZVS driver circuit Question 3 months ago. I was thinking of using it with 12V PC source But it does not work for me, with the laboratory source it reports a high current consumption.

Question 1 year ago on Step 7. Answer 8 months ago. Any higher voltages will blow up the mosfet. Question 9 months ago. Reply 2 years ago. Zeners have a defined breakdown at a reversed polarity, anything from 2. In some applications they help speed switching time by limiting the charge on the gate.

Is 1n a good replacement for UF? How would you go about getting more power output for lower voltages i. Is there a way to increase the efficiency of this circuit? Question 3 years ago. Could this driver circuit provide up to watts for a flyback transformer made to put out kVDC and mA?

Some use brute force, and the Stanley Meyers type use Resonance and High voltage. Maybe a modified Flyback, like you show here could be adapted to achieve the same result. Every time I hear people talking about resonance, I imagine a very complex process not fully understood. If you use electric power to split water in H2 and O2, burning the mixture will give you less power, so why bother?

Hey there Radu, Umm i build this ZVS driver once before and it worked well but now i have made this once again but its not working that well probably not working at all,iz it because the last time i used a 12v 4. You need thicker wires for primary, I use thick automotive wire and even those get warm.

If you do this, you will draw fat white hot 4 inch arcs at least! It puts out 24V 10Amps max, rectified and filtered I get 30V. Radu please help.. Note: for the supply i use 12v 10A smoothed not regulated, i also tried a battery 24V 5A but it did not work….

Radu… Thanks in advance.. Radu, may I know is it possible to generate a cold plasma by using flyback driver?? If the intensity of the current flowing through your discharge tube is small, you can get that temperature. Radu, can you please show me the way to do it?? Can I get that temperature just by provide a lower input to the flyback driver but using the common flyback driver circuit design?

Hi there, thanks for the article Radu! I just had a small question about the inductor. There are some SELFs out there but i don t fin that 0. Is that any good? Thancks for the quick reply! Interesting video. Last weekend i found a ferrite core in a old tv on the pavement.

I am also interested in the type of D5 diode used. Like what voltage its for Vrrm , is it dependant on whats the output voltage from flyback? OK, I built it. Whats and how to determine the frequency of this driver? So I guessed this circuit still need a power source. Does the power source need to be sinusoidal directly from a transformer , square wave or direct current? Yeah, I already plug it in.

Its cool. Too high ampage, so that my primary wiring melted, lol.. I will check with oscilloscope when I have time.. So this circuit convert DC to V high-frequency signal?

You determine what valtage you will have with the what voltage the cap is?? Sorry, I still did not check how the circuit works, I just put straight and build it, but as I say I will check with oscilloscope when I have some time.. I am still looking for some flybacks. If you have some TV flybacks, or know some other options.

Ohm, I did get the flyback, and already wire it, but its from plasma globe, and the ferrite core, looks a bit smaller than the ferrite core in TV flybacks or so it looks.

One problem which I got is that the capacitor gets really hot. Its the damn hottest component in that and I was lucky because shut it down, right before this things blow apart it bulges severly. Only which gets this hot is 2 resistors and I am using 10W resistors here , and one a bit more than the other! You will need a better quality capacitor, that can handle more current.

Also you will need a higher rated capacitor, in terms of voltage supported. I think they blow up, because my secondary wire was not coiled in the same direction as the primary. Can that be a problem? Any clue? Hi there! Got my homemade flyback, got most of the components lined up.. Just a little glitch left. My condensator actually is a DC condo, i didn t see it on the site, is it okay also or does the condo have to be AC? Second little question, the power, i was planning to put nimh batterie packs in parallel because of the ease to recharge and the weight of lead batteries.

Is it okay? What should i aim for, 12v 8ah, or could 7.
