Hi there guys! I tested my ZVS driver today and there was no output whatsoever. I checked the primary windings to see it the turns were going in the same direction, and the inductor and MOSFETs got warm, but still no output. I know there's something wrong, but can someone please help? I would love to get some advice and help from experienced people.

maybe the fbt is bad, If the curcuit is oscilating it will interfear with an AM radio.

I agree, the flyback could be bad. Has happened to me a handful of times. Also, simple mistakes always seem to be the ones overlooked the most often. Double check the direction of your diodes :)

Thanks for the help. I think the flyback is fine and I will check the ultrafast diodes for any errors... Yeah, i noticed that the diodes go to a specific coil side so I'll try that. I hope that the MOSFET's didn't end being blown because they warm themselves and the heat sink up in seconds. Hopefully, when I fix this, because I will, I will be proud. Once I get it working, I'll upgrade to a 36v PSU with the 3 extra windings with 100 ohm resistors. But for now, I need to fix it lol.
