I threw this together today using 2SK2698 mosfets ( 500v 15A - 60A pulse )
The DC input is choked and filtered and each channel can be driven by a signal generator ( i know i need mosfet drivers - thats next )
It will need a fan... but i am only planning on running it at 80v 1A
nice work Ds
Glad you worked out the problems with your sig gen's.
Thanks Peterae! - we will see how long it works ;D
