An Optimized Capacitor Voltage Balancing Control Strategy of Modular Multilevel Converter Based on Comparison of Variable Reference Values by Fengyang GAO, Guodong QIANG, Yunbo GAO, Guoheng ZHANG

“…This paper proposes an optimized balancing control strategy of the capacitor voltage based on the comparison of variable reference values. The number of current input modules is calculated by the nearest level modulation, then the reference value is adjusted according to the number of input modules, and based on this reference value, the sub-module capacitor voltage sequences are divided into two groups. …”
