Implementation of controlled rectifier with power factor correction using single-phase matrix converter

This paper presents an implementation of controlled rectifier with power factor correction (PFC) using single-phase matrix converter (SPMC). A current control loop (CCL) using standard proportional integral control was used to implement PFC to correct the pulsating nature of the input current to almost unity power factor form with low total harmonic distortion (THD) level well below the acceptable limit that was defined in the standards of IEEE 519. Waveshaping of supply current is facilitated through the use of boost technique that could perform corrections making it continuous, sinusoidal and in phase with the supply voltage. Safe commutation strategy was implemented to avoid voltage spikes due to inductive load. Prior to its practical realization a computer simulation model is developed to investigate the behaviour of the SPMC using MATLAB/Simulink (MLS). An experimental test-rig was then constructed to verify the operation; incorporated with control electronics, gate drives, and power circuits. Selected simulations and experimental results are presented to verify proposed operation.
