This paper presents simulation of AC to DC converter fed permanent magnet DC motor (PMDC) using single phase matrix converter (SPMC) topology. The use of AC-DC converter has a setback in that it draws non-sinusoidal supply current waveform with high harmonic contents. As a result it contributes to high total harmonic distortion (THD) level and low total effective supply power factor affecting the...
This paper presents the application of single-phase matrix converter (SPMC) as a single-phase AC-DC controlled rectifier incorporating active power filter as a battery charger. The output voltage of the charger should deliver a clean regulated voltage output with sinusoidal input current. A current control loop (CCL) using standard proportional integral control was used to correct the pulsating nature...
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...
