Model Predictive Control of a Modular Multilevel Converter with an improved capacitor balancing method

The modular multilevel converter (MMC) has a very good development prospect, however, still has a lot of problems and challenges, one of the essential problems is more intense computational burden with the voltage level of the MMC increasing. An improved model this method is reduced to decrease computational burden. The proposed improved method is verified by simulation system based on 11-level MMC using MATLAB/Simulink.
