Abstract
This paper describes implementation of safe-commutation switching sequence for controlled rectifier operation of Single-Phase Matrix Converter (SPMC). Pulse Width Modulation (PWM) technique was used to calculate the switch duty ratio to synthesize the output. The switching sequence is arranged by providing a continuous path for current flow during switch transition to avoid voltage spikes due to the use of inductive load. A computer simulation model was developed to investigate the behaviour using MATLAB/Simulink (MLS) and PSpice. An experimental test-rig was then used to verify operation; incorporated with control electronics, gate drives, and power circuits. Selected simulations and experimental results are presented to verify operation.
