Oh yea...
I've almost crawled out of the Unicorn Corral....
I did manage to get DesignSpark working, and I'm currently untangling the rat's nest to make a PC board.
I did find some AWESOME IGBT's to drive this thing with.
A few Silicon Carbide IGBT's in the 1200V > 1700V range are becoming available. Cree makes a half bridge that looks like it would directly connect to this driver board! Also, GeneSiC is making some individual switch moduels for the SOT-227 format. All these are in the 100A to 300A range, and include a SiC diode.
This is really exciting. The SiC losses are about as low as I can imagine, and they seem to get more efficient as you push them to higher switching frequencies. Cree is talking about 99% efficient. You almost don't need a heat sink.
