Implementation of a new Single-phase Cycloconverter based on Single-phase Matrix Converter Topology using Sinusoidal Pulse Width Modulation with Passive Load Condit

In this work the single-phase matrix converter (SPMC) topology for cycloconverter operation are proposed for direct AC-AC conversion with step-down frequency operation. The well-known sinusoidal pulse width modulation (SPWM) scheme is used to synthesize the output. 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 developed to experimentally verify the result. Good agreement was obtained between simulation and laboratory experiments
