© 2014 IEEE. A new space vector modulation (SVM) strategy is proposed for quasi-Z-source indirect matrix converter (QZS-IMC) to reduce common-mode voltage and to ensure a high voltage transfer ratio. QZS-IMC's common-mode voltage is analyzed, and the subdivided sectors are employed to rearrange switching sequence in the inverter stage, which can reduce common-mode voltage and power loss. The proposed modulation method mitigates the peak value of common-mode voltage by 42% and reduces the switching losses in the inverter stage. Experimental results verify the proposed method.
