Fault Tolerant AC-AC Single-Phase to Three-Phase DC-Link Converter

A fault tolerant system considering a single-phase to three-phase power conversion has been proposed in this work. Two kinds of failures occurring in the converter power devices, open circuit and short circuit, can be compensated by proposed system. The fault compensation is achieved by reconfiguring the power converter topology with the help of isolation and connection devices. These devices are used to redefine the post-fault converter topology. A proposed control strategy allows to keep the post-fault topology operating at same power rate of the pre-fault one. Simulated and experimental results are presented.
