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...
