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

This paper describes the power losses and the switching effects that might occur in single-phase matrix converter (SPMC) as an AC-DC controlled rectifier if frequencies vary. The MPWM 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. Loads represented R, RL and RC circuit are used for this investigation.
