DC-link voltage balancing method for a hybrid asymmetric multilevel converter

The paper presents the dc-link voltage balancing method for a five-level hybrid asymmetric multilevel converter based on a neutral point clamped (NPC) converter with H-bridge (HB) converters. The considered converter, which is referred to as NPC-HB, is treated in this paper as a modification of the classic three-level NPC converter. It improves the harmonic… CONTINUE READING
