    Happy flyback

      I think it is starting to get mad at these voltages and output power! The diodes are definitely dead :p

    Explantation of circuit... What type of driver circuit has you used to drive flyback? ZVS or NE555 timer circuit: please ask. Without schematic would be waste time.

      I havent drawn a schematic of the exact circuit i am using, but this circuit is using the ir2153 halfbridge driver. There is only 1 IC, 2 IGBTs or MOSFETs, one diode and some passive components. All parts used in my circuit came from circuit boards from TVs I have taken apart except for the ir2153, which I got 20 on eBay for around 15usd. This schematic is very similar to mine, I just used some extra parts for durability, never killed a single part. danyk.cz/iz_2_35_en.html This circuit is very similar to mine, except instead of the transformer he used there is a flyback with a primary of about 15-30 turns (less turns=more current and more power). I am in usa so I have 120v mains, but as you can see by that schematic on that webpage, it works for 230v as well. If correct parts are used this ir2153 can go as high as 600v

      It is just an ir2153 halfbridge driver with a few resistors, capacitors, and 2 mosfets. It is practically exactly the same circuit as in the datasheet's application circuit, just with some zener diodes to protect the gates and some TVS's to clamp the voltage across the drain and source though they aren't strictly necessary.

      @@Headbutter-Lettuce90 As a matter of fact I did! I just used an antenna for feedback, cleaned up the signal with a 74hc14 hex inverter, and connected the output of the 74hc14 to the timing capacitor pin of the half bridge driver. Worked great, quite efficient thanks to the gate driving characteristics and proper dead time of the gate driver! I've also made a simple full bridge class D amplifier using 2 of them, which I have a video of that amplifier before I worked all the bugs out on my channel if interested.

      I should mention that I had to use a fairly large coil with very fine wire and a topload for lower resonant frequency, the gate driver couldn't drive the gates at the ~400khz resonance of one of my smaller coils
