Implementation of Single-Phase Matrix Converter as a Direct AC-AC Converter with Commutation Strategies

This paper is concerned on investigations in implementations of the single-phase matrix converter (SPMC) as a direct AC-AC converter subjected to passive load conditions. The output voltage was synthesized using the well-known sinusoidal pulse width modulation (SPWM) technique. A Xilinx field programmable gate array (FPGA) was used to implement the controlling algorithm with IGBTs as power switching device. Prior to hardware implementation, simulations were performed to predict the behaviour. A laboratory model test-rig of the SPMC was then developed to experimentally verify the result. Good agreement was obtained between simulations and experiments
