Abstract

In this paper, a space-vector-modulation method for indirect matrix converters is proposed to improve the output voltage quality in high modulation index ratios and to reduce the peak common-mode voltage (CMV). A novel approach in the rectifier stage modulation generates a variable dc-link voltage that is controlled to drive the inverter stage on the limit of the linear modulation during each switching period. This allows inherent formation of the output voltage using only two active vectors per sector, which reduces the peak CMV and enhances the output voltage quality. Analytical and experimental studies are carried out to validate the feasibility and the benefits of the proposed modulation technique.
