A New Single-Phase Controlled Rectifier Using Single-Phase Matrix Converter Topology Incorporating Active Power Filter

摘要

This paper presents application of single-phase matrix converter (SPMC) as a single-phase AC-DC controlled rectifier incorporating Active Power Filter to ensure that the supply current is continuous, sinusoidal and in phase with the voltage. For basic rectifier operation, 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. Basic loads represented by R load, RL load and non-linear loads are used for this investigation. Selected simulations and experimental results are presented to verify the proposed concept.
