Astro: Yes I was using a pickit 3. I programmed that board probably 9 billion times! No exaggeration either! haha

I'm almost done with a new power board that will use TO-247 IGBTs. I'm hoping for a 100kW AC controller for $300 in parts. I also made a new current sensor board that mounts to the power board with maybe 1/8" standoffs. It uses 3 IGBTs per high and low side (so 6 per phase). They have some remarkable TO-247 plus igbts that can do 80-100amp continuous now. Also, it uses a fairly small 450v 800uF ring capacitor that just bolts right to the power board, so you don't have to cut out any copper sheets and bend them. I hope it works!
