基于半波对称选择性谐波消除技术的三相多电平变换器多故障容错策略

This paper presents a generalized fault-tolerant strategy to improve the performance of the three-phase cascaded H-bridge converters with faulty cells. The proposed fault-tolerant strategy combines the fundamental phase-shift compensation (FPSC) method with half-wave symmetrical selective harmonic elimination (SHE) to rebalance the inverter voltages and limit the total harmonic distortion (THD) of...
