Abstract

Matrix converters have become popular due to their capability for direct ac-ac conversion without a dc-link capacitor. Several modulation methods have been proposed for matrix converters including Space Vector Modulation (SVM), which has been widely used in conjunction with numerous different control approaches as it can ensure sinusoidal input and output currents with unity power factor and fixed switching frequency. Model Predictive Control (MPC) is a control strategy introduced recently for power converters with several benefits like fast transient response and possibility to control multiple variables without cascaded loops; however it produces a variable switching frequency. This paper introduces a new control technique for direct matrix converters that combines the features of the classical MPC and SVM technique into a Modulated Model Predictive Control (M2PC) with fixed switching frequency. Simulation results showing the effectiveness of the method in controlling a direct matrix converter feeding a passive RL load are presented in this paper.
