Abstract

A multiphase matrix converter (MC) is a direct AC/AC converter with n -phase input and m -phase output that is required to supply multiphase systems. To synthesize the controllable sinusoidal output voltage and input current with controllable displacement angle, the pulse width modulation (PWM) is implemented. On account of the PWM usage, there is common mode voltage (CMV), which is detrimental and causes lots of failures. This paper investigates the CMV elimination in the three-to-nine-phase MC. The carrier-based space vector modulation (SVM) with Venturini modulation functions is used. The elimination of the CMV is realized by applying rotating voltage space vectors only. The simulation results presented in this study show that the CMV is entirely eliminated and prove the usefulness of the proposed modulation method.
