一种用于三相六开关电流源整流器的简化开关短路容错方案

This letter proposes a simplified switch short-circuit fault-tolerant scheme for three-phase six-switch current-source rectifier (3P6S-CSR). By only adding two diodes in parallel for each phase, the active switches are not affected and the ones in the same phase are mutual redundancy. Then, the 3P6S-CSR can be reconstructed into a novel fault-tolerant structure under multiple switch short-circuit ...
