ZVS Flyback Driver - 24 volt 17 amp input (408 watts)

Homemade ZVS (Zero Voltage Switching) Flyback Driver running with 24 volts @ 17 amps from two ATX PSU's (12v rails @ 17amps in series). Flyback is from a Computer Monitor or Color TV (don't remember, I have several) with hand wound 6+6 center tapped wound with 14 AWG Automotive wire. ZVS main Capacitor is about 2uF - 250v and another red PP cap (near the flyback) about 2uF 200v. Two toroid inductors pulled from dead ATX PSUs one with 17 turns the other with 40 turns, both high current rated. Currently using 2x 0N05HD High Speed MOSFETs (50v - 60amp - 0.014 ohm rds(on)) which are not high voltage enough but somehow seem to survive pretty well without blowing. Going to replace them with IRFP264 which are High Speed 250v 38amp 0.075 ohm rds(on). Google "ZVS Driver" for schematic.

Also, the Meter is showing current (amps) being drawn from the power supply. It goes up to 17 amps right at the end.

Nice, I cant wait until I get my ZVS to work. Once I know it is working, I will upgrade to HGTG30N60A4D IGBT's. With those IGBT's in there I can push flybacks until they explode :D
