Bad news lou. You would need to derate 50% to have any hope of the devices surviving. So a 400amp igbt is really good for 200amps or 250 at a stretch. My 500amp controller in the car uses "800amp" igbts.

Now, Cole, when you shift the gear and that little needle on the ammeter goes into the red and reads 2000 Amps, that's bad.
