the 213v is phase to phase, 176v (peak) phase to neutral, purple is what one motor coil would see if you ran this in reverse (resistor is a 300v battery, diodes are igbts switching red blue cyan 120 degrees out, the lines to the voltage source are the motor leads.

I don't think so, you can do the same reverse maze thing with a full wave rectifier also.
pretend the voltage source below is actually a single phase motor, and that the diodes are doing igbt switching a-la red and blue lines (300v is 100% duty cycle upper leg, 0v is lower igbt on, upper off) and the resistor is a 300v battery, you will get 600v peak to peak out (purple again, it is the source below), which is 300v peak which is 213vrms... My spidy sense tells me that is all you can get out of a 300v battery and a full bridge.
