摘要：
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 the proposed strategy. 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 topology. Simulated and experimental results demonstrate the validity of the proposed systems.
