DUAL CONVERTER CONTROLLED SINGLE PHASE MATRIX CONVERTER FED DC DRIVE

This paper presents an application of Single Phase Matrix Converter (SPMC) as a dual converter. Pulse Width Modulation (PWM) techniques are used to calculate the switch duty ratio to synthesize the output. Chosen PWM technique incorporating wave shaping is also used to ensure continuous supply current. Basic loads represented by R, R-L, motor loads are used in this investigation. The performances of chosen DC drive with SPMC based dual converter and SCR based dual converter are compared and analyzed. Selective simulation results are presented to verify the strategies developed. It is found that SPMC is a versatile topology.
