Description
Summary:The traditional space-vector pulsewidth modulation (SVPWM) maximum voltage transfer ratio (VTR, i.e., the ratio of the output voltage fundamental amplitude to the input voltage fundamental amplitude) is 0.866 in a linear modulation region. In this paper, the output voltage fundamental amplitude and total harmonic distortion (THD) affected by a basic vector and a hexagon vector in traditional indirect SVPWM overmodulation are analyzed. The traditional indirect SVPWM overmodulation usually focuses on the inverter stage to improve the VTR, and there are few methods considering both of the inverter and rectifier stages to improve the overmodulation performance of a matrix converter (MC), including output voltage error, and output and input current THDs. In this paper, a new overmodulation method based on indirect SVPWM is presented. Both the output performance and input performance of the MC with the proposed and traditional overmodulation methods are emulated and tested. Simulation results indicate that the output voltage error and the input current THD are smaller and lower, respectively, with the proposed method. Experimental results verify that theoretical analysis is right, and the proposed overmodulation method is feasible.
