12vdc ==> 30Khz astable multivibrator using only 2 power transistors ==> step up xfrmr ==> Cockroft Walton ==> 30Kv with 1kv 30Hz ripple.
Compactt, simple, rugged, Portable source of 30Kv DC but with a 30Khz ripple so you can have ultrasonic/low RF
Designed and built prototype but it doesn't work. Need you to fix/redesign it so it does.
Ultimate goal is to power an ultrasonic plasmatron which will be the ignitor in a microturbine that can burn any fuel such as hydrogen, HHO, gasoline, diesel, etc
I will ship you the prototype and schematic. If you can replace the center-tapped step-up transformer with a better part that would be great also.
