| Abstract |
This paper deals with the transient process of switching off an Interior Permanent Magnet Synchronous Motor (IPMSM) by a Current-Source-Inverter (CSI) in the event of malfunction in a Battery-Electric-Vehicle (BEV). A method containing a voltage observer based control to switch off the IPMSM is developed in order to avoid undesirable side effects caused by high transient currents and voltages during the switching off process. The performance of IPMSM under short circuit operation is analyzed including the transient currents, voltages and the torque development. |
