Abstract：When the permanent magnet assisted synchronous reluctance motor（PMaSynRM）runs at highspeed with flux-weakening control，the DC bus voltage utilization is not high，and the efficiency and torque output capacity of the motor are low. Therefore，a flux-weakening control strategy of permanent magnet assistedsynchr...

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...
