A Single to Three-Phase Z-source Matrix Converter

In this paper using matrix converter theory and Zsource conversion concept, a single to three-phase Z-source matrix converter (STZMC) is proposed. With the proposed converter and switching strategy, limitations of single to threephase matrix converter (STMC) such as lower input-output voltage transfer ratio and unbalanced output currents is improved. The proposed direct ac/ac converters can boost amplitude of output voltage with desired frequency. A simple switching strategy based on sinusoidal pulse width modulation (SPWM) strategy for Z-source inverter, is presented for proposed converter. The operating principle of the proposed STZMC is described. Simulation results verify validity and performance of the proposed converter
