70-100V powered ZVS?
So I was playing around with my ZVS driver and I turned up the variac to 40V, getting roughly 100kV and boom the flyback caught on fire and my ZVS driver fried. So I want to build a new one that could handle around 70-100V input. I know that for higher inputs some component values need to be changed but for voltages that high, I do not know exactly what would need to be changed. I was thinking of using two STY34NB50 MOTFET's, but wasn't sure if they were the right kind.
