This paper proposes a new type of converter called Single Phase Z-source Matrix Converter (SPZMC). The SPZMC is an ac-to-ac converter device. Simulated using diode bridge bidirectional switch cell. The simulation is performed in different loads with fixed input and variable output frequency. Pulse Width Modulation (PWM) switching strategy is used to obtain the variable frequency. The Z-source network provided the good voltage regulation with change in load conditions. The proposed converter presented improvements in power factor and achieved low total harmonic distortion (THD) level. And SPZMC also improves the output waveform quality with high voltage gain.. The simulation results are verified with the prototype hardware model. The results are presented to verify the operation.
