Power losses and switching effects in single phase matrix converter for rectifier operation / Shazrul Musa

This thesis presents the power losses that arise in single-phase matrix converter (SPMC) as an AC-DC controlled rectifier with respect to frequencies variation. The Multiple PWM technique was used to synthesize the DC output. Switch commutation arrangements were developed that allow dead time to avoid current spikes of non-ideal switches whilst providing a current path for the inductive load to avoid voltage spikes. The simulation of model SPMC as a rectifier was done by using MATLAB/Simulink. Loads represented R, RL and RC circuit are used for this investigation.
