New plan: abusing a MOSFET gate driver to drive a SCR's gate to get high-side switching. Now I need to figure out how much Common Mode Transient Immunity do I need. My circuit is *literally* a surge generator. #electronics

CMTI: 100 kV/μs. Oh, it's more than enough... #electronics

Rewired the isolated DC-DC converter to float on top of the high voltage instead of ground. No more explosions, even a small-signal transistor can drive the gate with ease. #electronics

Look at my gate turn-on waveform... Man-made horrors beyond comprehension. #electronics

A step signal, with extremely large overshoots and ringings for several microseconds at the rising edge.

In electronics, everything is an LC resonator if your layout is bad enough. #electronics
