A Novel Modulation Strategy and Simulation Study for Matrix Converter

A novel over modulation strategy for matrix converter (MC) is put forward on the basis of conventional AC/DC/AC MC control theory. First, fictitious AC/DC rectifier is over modulated to get the greatest dummy DC voltage, then a novel over modulation strategy was invented for the inverter side, which effectively enhanced voltage transfer ratio to 1.05 with good linearity. At last, the method was extensively investigated with MATLAB under both output voltage and spectrum wave. Simulation results showed that the over modulation methodology proposed in this paper was feasible and liable, which provide a theoretical basis for further research.
