Abstract
A novel fault-tolerant power converter topology is developed based on conventional active neutral point clamped (ANPC) converter. The effect on converter performance due to open/short circuit faults of power devices is investigated. By leveraging the redundant leg in the proposed topology, the lost voltage vectors in the space vector diagram can be restored. This new fault-tolerant topology is capable of maintaining the full output voltage and maximum modulation index during post-fault operation stage. A 25-kW converter prototype based on using 1.2kV SiC MOSFETs has been built in the laboratory, and the experimental results verified the efficacy of the proposed fault-tolerant ANPC converter.
