Yeh i think the toshibas would work well. i'm too tired right now to go looking up switching times but i did drive them quite hard in a charger design quite recently and they worked well. 700v dc bus and 100amps DO put a good snubber between B- and M- and poly caps in parallel with the elecs. To my surprise my caps ( 4 big 400v comp grade elecs) are showing no sign of distress. Another ebay guy in new york sells caps at good prices.

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.
