An improved four‐layer capacitor voltage control strategy combined with arm current control for transformerless modular multilevel converters

Abstract In order to improve the performance of the transformerless modular multilevel converters (MMC) under AC and DC grid fault conditions, this paper proposes an improved four‐layer capacitor voltage control strategy combined with arm current control. The proposed control strategy consists of ov...
