Demo Model Video - PLECS: Motor Drive with Failure Modes

This video corresponds to the PLECS demo model of a current-controlled permanent magnet machine under several drive fault mitigation strategies. The system includes an inverter with field-oriented control that supplies the machine operating at a constant speed. Fault conditions such as loss of auxiliary power supply or microprocessor trip can result in loss of power to the inverter. In this simulation, failure mitigation strategies by closing all the lower inverter switches or opening the battery pack contactor are investigated.
