Geometrical Visualization of Indirect Space Vector Modulation for Matrix Converters Operating with Abnormal Supplies
Guan, Quansheng; Guan, Quanxue; Wheeler, Patrick; Simon, Olaf; Clare, Jon
Matrix Converters can be sensitive to abnormal supply conditions due to the absence of energy storage elements. This sensitivity can get worse when the Matrix Converters are modulated by a traditional Indirect Space Vector Modulation that assumes the input variables are sinusoidal and balanced. Therefore, this paper proposes a methodology for the modulation of Matrix Converters without requiring any assumption of the input voltages. The method uses a geometric representation based on the Singular Value Decomposition of the switch states to synthesize the rotating vectors of the target duty-cycle matrix. Furthermore, this paper mathematically highlights the factors that have regulate the amplitude of the output voltages and utilizes them to compensate the adverse effect of the abnormal input voltages. Experimental results presented in this paper validate that the proposed method can provide sinusoidal and balanced output currents in the presence of abnormal supply conditions.
