A Voltage Balancing Control Strategy for Modular Multilevel Converter Based on Allowable Capacitance Voltage of Sub-modules

Aiming at the problems of high switching frequency, large switching loss and large amount of computation in traditional voltage balancing strategy for modular multilevel converter (MMC), an improved capacitor voltage balancing control strategy is proposed. The sub-module (SM) voltage is constantly k...
