Abstract :
This paper presents a method to switch off an IPMSM by using a Current-Source-Inverter in the event of a malfunction in a Battery Electric Vehicle. The analysis includes transient currents, voltages and the torque development during the switching off process. The investigated method based on a voltage observer is able to minimize undesirable side effects caused by high transient currents and voltages.
