PROPULSION_INVERTER_CTRL
VVVF traction inverter supervisory control — d-q current references, output frequency, modulation index, field weakening and trip management.
When to use it
Use PROPULSION_INVERTER_CTRL when a traction converter takes a torque and flux setpoint from the vehicle control and the supervisory layer has to compute and bound those references, follow the drive into field weakening, and manage its trips and reset.
