DAVID!!!!!! Holy cow!!! that's awesome! I've been distracted by the DC controller lately. That's so great! I think I have a lot to learn from you! I'm so glad you wrote on here!!!!! I have a mosfet based low voltage power stage that is good to around 150v peak, but I haven't tested it yet. I've just been so dang blasted busy. The igbt power stage I did first worked OK, but the 0 to 15v driving wasn't working very well. Very long turn off times, so I made a driver board specifrically for igbts. basically a copy of the bg2a from powerex, but I haven't populated the board yet. I had a pmsm motor that I was trying to get working with the field oriented control, but I need time, dang it! haha. I can't wait to go watch your youtube video. Thank youso much for posting on here!!!
