Abstract in another language

Fault-tolerant converters are required for applications
with a high risk of damage or financial loss,
like electric aircraft or energy transmission systems.
The Active Neutral Point Clamped (ANPC) inverter
is a fault-tolerant multilevel topology, which enables
an ongoing degraded operation after single semiconductor
failures, if no secondary failures caused
by over-voltage and short-circuit currents occur.
This paper investigates the critical failure scenarios
of a three-level ANPC inverter prototype built
with 650 V SiC MOSFETs. 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 presented. Thus, a very efficient
and fault-tolerant inverter for applications with high
availability requirements can be realized.
