IGBT Rectifier Gate Voltage
As it turns out the pulses were out of sync, they were shifted over. This effectively created a short between gate and collector. It turns out that setup automatically triggers each device correctly and at the right time as the emitter falls below gate/collector by Vthreshold for that section.
This maybe useful as an autonomous rectifier without any control.

I wanted control over the gate voltage so with the right pulse timings I can reference it to the emitter and works as expected.
