A New Single-Phase Controlled Rectifier Using Single-Phase Matrix Converter

This paper presents the applications of single-phase matrix converter (SPMC) as an AC-DC controlled rectifier. For basic operation the multiple-PWM technique was used to calculate the switch duty ratio to synthesize the output. Safe commutation strategy was developed to avoid voltage spikes due to inductive load. Active current wave-shaping technique are also proposed to ensure that the supply current waveform is continuous, sinusoidal and in phase with the supply voltage. This approach utilizes boost rectifier technique for compensation. Selected experimental results are presented to verify the concept.
