A whole control strategy for cascaded H‐bridge rectifiers under distorted grid voltage and unbalanced load

IET Power Electronics, 2023
Control for single‐phase cascaded H‐bridge rectifier (CHBR) under distorted grid voltage is seldom discussed in the existing control methods; a modified direct power control (DPC) scheme is therefore proposed in this paper.
