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