In most applications, fault tolerance is a highly desired feature and it is obtained through redundancy. This paper proposes a fault tolerance solution for the SRC, which could drastically reduce the need of redundancy. Using the proposed scheme, the full-bridge based SRC or multilevel based SRC can be reconfigured in a half-bridge topology, in order to keep the converter operational even with the failure (open circuit or short circuit) of one switch. Since the proposed scheme can be applied to the FB-SRC and multilevel SRC, a family of fault-tolerant converters is proposed in this work. The advantage of the proposed approach are: minimum additional hardware and no deterioration of the converter efficiency. The proposed fault tolerant solution was experimentally tested in a 10 kW SRC prototype with input/output voltage of 700 V/600 V. A short-circuit fault in a semiconductor is tested and the results confirm the effectiveness of the proposed approach. 4950 https://doi.org/10.1109/APEC.2017.7931181$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8-publ-17550$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/publ_mods_00001755 5051 621.3 5550 Power electronics
