A New Space Vector Modulation Strategy Based on MC

Abstract

This paper presents a control method based on space vector modulation matrix converter (SVMMC). The method calculate the corresponding rotating voltage space vector according to the expectations of output voltage, and use the strategy which the paper presents to adapt the expectation of the output voltage space vector. Through theoretical derivation, the method of the algorithm is given. Using the control method proposed in this paper will greatly simplify the modulation strategy, the output voltage of matrix converter well follow the expectations of a given voltage, and can effectively inhibit the matrix converter output voltage and input current waveform distortion. The simulation results verify the correctness of the theoretical analysis.
