Practical considerations in the PWM rectifier with active filter function

Abstract

This work claims to identify the possible problems and limitations caused for the inclusion of the active filter function in a three phase PWM rectifier (PWM-VSR-C). Basically, the following topics are covered: the study of the PWM-VSR-C as a reactive power source, calculations of apparent power and dc bus voltage requirements, a study about the electric system around the PWM-VSR-C and the variation of the losses, due to the inclusion of the active filter function. Experimental work is included to validate the main results.
