Homemade flyback transformer 450 watts

!: Homemade flyback transformer 450 watts

Here is a quick video of my homemade flyback running at approximately 450watts. Power Supply: Two 24V @ 10A (240Watts) transformers; No regulation straight off full bridge rectifiers to capacitors then to the output. Output under full load ~45V @ 10A, 450Watts Driver: Standard ZVS type; IRFP250's; 0.68uF cap; unknown inductor (it works); 12V @ .5Watt Zener's (with 10kOhm resistors parallel); 1kOhm @ 2Watt resistors; U860 Diodes (TO-220 case). Custom PCB using terminal block connections for quick changes (swapping out fried components). Flyback: Secondary ~ 1000 turns 30awg wire; Primary 10 turns CT (5+5); Output ~7kV @ 64mA The gap is purely designed to protect the transformer's secondary from open circuit overvoltage. The secondary doesn't have enough insulation to run open circuit it's made to run a voltage multipliers or in full short conditions, which it does very well (never had it even get warm). Running in full short isn't very impressive looking for a video so here's one of it's overvoltage "arrestor" doing it's job. Enjoy!
