That'll do, Oprah. That'll do. (Babe, slightly modified)

Hi Ben! I got the driver board done for the possible motor link that you sent to me. I also got one done that would be for IGBTs and super high voltage. I've found some big gosh dang igbts in a TO-264 package. Rated for like 200-250 amps each and 600 volts, and they only cost around $12 or $14 each. The same sort of thing that the 1000amp controller uses can be done with them. Just solder their backs to copper plates, and clamp the plates against the heatsink. I think a 300-400amp per phase AC controller would be pretty dang cheap. It would require a chassis mount film capacitor or 2 though rather than the crap electrolytics. And the 6 isolated drivers are only a couple dollars each since I have a super fancy way to do it!
