An Enhanced SVM Method to Drive Matrix Converters for Zero Common-Mode Voltage.

This paper presents an enhanced space vector modulation (SVM) method to drive matrix converters (MCs) with zero common-mode voltage by using the rotating vectors, which are not used in the traditional SVM for MCs. The reference output voltage vector is generated by a combination of the closer rotating vectors in order to minimize the output distortion. Explicit equations are used to develop the switching patterns so that the proposed SVM method can achieve full control of the output voltage vector and input current phase angle with good performance of the input/output current waveforms. Together with the theoretical analysis, the experimental results are provided to validate the feasibility of the proposed method. [ABSTRACT FROM AUTHOR]
