Just a reminder, we had arbitrarily set the upper limit @ ~36kw for a 144v battery, so that limit has been my focus primarily (510v@70a to beat on some 18kw 200-240v motors with at 2x rated speed), which I assume you would gear down for 2x torque if you like.

I do like the boost topology best (short of rewind), it beats on the source the least and allows a direct path to the motor when all those volts aren't needed.

Can you expand on the center tap=3 igbt idea?
