Continuous control set space vector modulation for the 3×3 direct matrix converter

Abstract

In this paper, a new method for Space Vector Modulation (SVM) for the 3×3 direct matrix converter is proposed. This method is based on a combination of Model Predictive Control (MPC) and SVM, also denoted as Continuous Control Set MPC. The proposed method uses all available vectors, and allows the converter to produce waveforms of high quality at both power ports, also when subjected to unbalanced or distorted waveforms. The mathematical derivation of the proposed method is explained, and the operation illustrated by means of simulation experiments in open loop. The paper finishes with conclusions and prospects for further development and application of the method.
