Simulation of buck or boost rectifier using Single Phase Matrix Converter with reduced switch count

Single Phase Matrix Converter (SPMC) operating as buck or boost rectifier with reduced switch count is illustrated in this paper. Six switches can be used in the proposed configuration as compared to eight switches in conventional SPMC, by removing two unused switches for buck or boost rectifier operation. Both buck and boost rectifier uses same circuit topology with six switches and R load. The operation of both buck and boost rectifier are observed and variation of output voltage with modulation index is analyzed. To synthesis the output pulse width modulation (PWM) technique is used. Buck and boost rectifier circuits are modeled using MATLAB/Simulink and selected simulation results are shown in this paper.
