Michael, You are correct. i have my enable going to a mpsa42 that is providing ground to a mpsa92. the hv output goes through the a92. I am using an IPD60R380C6 650v mosfet with a Id of 30A and a 100uH inductor. past that i have a RS1GFS Diode and 2 .47uf 400 volt caps in parallel. The voltage input is the only downside. I can't go down to 2v.
