Hierarchical voltage balancing method for MMC based on DCSM

Abstract This paper presents a hierarchical voltage balance control method for a hybrid modular multi‐level converter based on half‐bridge submodule and dual‐capacitor submodule. This voltage balancing method reduces the control complexity of the existing voltage balancing method of the central cont...
