3 phase inverter fails to simulate

I will help to review it later.

Anyway,

  1. maybe you can replace the diode model with behavioral ideal model (you can define vfwd, ron, roff)
  2. since you dont use any deadtime you can remove the antiparallel diode.
  3. you can replace the behavior of the low side gate driver as V = 5 - V(hi)
