Holy cow, what are the dimensions on that heat sink, it looks huge?!
By the way, the IGBT based controller I posted on a while back is in the car and tested up to 30 mph. So far I just have 80v in batteries and have the current limited to 300 amps. I'm just starting to test my battery charger, but once that's done I'll be ready to test at 230 volts.
