Single-phase matrix converter with reduced switch count operating as buck or boost rectifier

This paper presents Single-Phase Matrix Converter (SPMC) with reduced switch count operating as buck or boost rectifier. Instead of eight switches, SPMC with reduced switch count employed six switches due to redundant switches that present in previous buck and boost rectifiers using SPMC. Both buck and boost rectifiers are using the same proposed circuit topology which only six switches are being used with the same parameters of the RC load. The performance of buck and boost rectifiers is observed and the relationship between output voltage with the variation of modulation index is analyzed. Pulse Width Modulation (PWM) technique was used to synthesis the output voltage. These proposed circuits are being modelled using MATLAB/Simulink and verified by experimental test rig. Selected simulation and experimental results are presented for verification.
