MMC (modular multilevel converter) is a voltage converter with good character, such as low harmonic, no additional filters and transformers, suitable for modular produce etc. However, due to the bridge arm of MMC cascading multiple sub-modules, balance control of the sub-module is needed, and the balance between the various sub-module control systems affect the normal operation of MMC largely. This paper presents an optimized carrier phase SPWM modulation strategy and the sub-module capacitor voltage balance control strategies. The feasibility and effectiveness of control strategy proposed was proved with the simulation result by PCAD / EMTDC.
