Abstract

This paper presents a novel quasi Z-source Hybrid modular multilevel converter (qZS-HMMC) for medium voltage applications where the “hybrid” concept refers to the implementation of the MMC strings that consist of a mixture of half bridge sub-modules and full bridge sub-modules with aratio of 1:1 whilst the use of two quasi Z-source networks provides voltage boosting capability. The authors previously proposed a reduced inserted cells (RICs) modulation technique to control qZS-MMCs which has been modified here to modulate the proposed converter. Relevant simulation results are presented to verify the capability and the operation of the proposed converter topology.
