12V in, 70+KV out, mosfet controlled. To get the sim to work it must be started witht the switch closed, after the start open and close the switch and after three cycles on mine it stabilizes to produce its desired output. I would appriciate some constructive criticism on this. Mainly, can any mosfet survive the 8KV present upon opening the switch? (May not be required in a real circuit) I know arcing would be a huge issue but remidied with submersion in mineral oil. Also, what are youre opinions on how this circuit would actually operate?
