Abstract :
For the two-stage matrix converter (TSMC) having no energy storage elements, the nonsinusoidal supply voltages will disturb the output voltage and result in low order harmonics. To compensate the output voltages, two new space vector modulation strategies are presented. One works with the rectifier stage, and the other with the inverter stage. The maximum transfer ratio under nonsinusoidal input is obtained by detecting the minimum amplitude of the nonsinusoidal input vector. Theoretical analysis and simulation results indicate that the output voltage is sinusoidal, and at the same time, the input current harmonics decrease.
