What is Reduction of THD and low order harmonics with symmetrical output current for single-phase ac/ac matrix converters about?

In this paper, the modulation strategies are developed for single-phase ac/ac matrix converters. These are named positive, negative and combined switching strategies. Reduction of low order input and output currents harmonics with sinusoidal output voltages is achieved using the proposed switching strategies. There are no low frequency harmonics in the output voltage, as well. Furthermore, total harmonic distortion (THD) is reduced significantly. Using the combined switching strategy, the symmetrical output voltage and current can be achieved. The converter with the proposed switching strategies has been modeled and simulated by PSCAD software. The simulation results have a good agreement with measurement results.
