Abstract in another language
Fault-tolerant converters are required for applications with a high risk of damage or financial loss, like electric aircraft, autonomous vehicles or energy transmission ap-plications. The Active Neutral Point Clamped (ANPC) inverter is a fault-tolerant multi-level topology, which enables an ongoing degraded operation after any single semi-conductor failures, if no secondary failures caused by overvoltage and short-circuit currents occur. The critical failure scenarios of a single-phase ANPC prototype built with 650 V SiC MOSFETs are investigated in this paper. Innovative driver integrated measures for immediate short-circuit detection, over-voltage clamping and switching strategy reconfiguration in order to enable a reliable ongoing operation are present-ed. Moreover, the operation range of a permanent synchronous machine in degraded inverter operation mode is explained. Thus, a very efficient and fault-tolerant inverter for applications with high availability requirements can be realized.
