Hi Erik! According to the datasheet for the mosfets, the legs are good for 160amp, and the actual mosfet is good to 230amp (ya right). So, I was thinking that with good heatsinking, they might take 100 amps each for some amount of time that is to be determined. I'm using the TO-264 package, but the TO-247 plus package has the same ratings. The big black bus capacitors are these:
EET-ED2D102CA Panasonic Electronic Components Aluminum Electrolytic Capacitors - Snap In.
It's the same ones that I have been using in the DC motor controller. I'm also using some metal polypropylene caps right at the mosfet legs (from B+ on the high side to B- on the low side):

There are a few quirks during assembly that I have encountered so that the power board should be tweaked a bit.
I think 144v is safe with these 200v components because people have been using 200v components at 144v nominal on the DC controller (so really like 150's), and it seems to be working well.
I've added voltage monitoring to the DC board, and will add to the AC board too. That will make regen safer. You can have the AC control board files. It's through-hole, so the dang thing is big. I need to convert it to surface mount. Change whatever you want. It's a little overkill right now. There are 6 isolated DC-DCs, but you really could get away with only four I think. 3 high side, and 1 for the 3 low side ones.
