Abstract: Based on full-bridge(FB)and half-bridge(HB)sub-modules(SMs),the conventional hybridmodular multievel converter(MMC)is a typical topology of MMC with DC fault clearing ability. However,theproportion of FB SMs in conventional hybrid MMC is usually greater than 50%,so as to increase the cost andlosses. To sol...
