Well, with kV diodes and kV MosFETs I'm still blowing things up, even
after severely damping the input inductor. I think maybe the parts I am
using are just too fast, so that parasitic inductances are ringing up.
Also, I am using a UC2710 MosFET driver, which is probably producing an
extremely fast rise time on the gates. Its capable of more than 6A
drive. Maybe I need to sim with 1nS risetime pulses :) That will make
for a very long sim. Rob.
