It sounds like the margin of error might be getting a bit slim if using 200V mosfets with 144 battery voltage. 144V + 25 = 169 V. It's still 31 volt leeway to take into account an errant spike here and there, though. Does anybody know if there have been any problems with the 200v mosfets blowing? I'm considering 250V mosfets vs IGBT's. Anybody know anything about paralleling IGBT's?
