Experimental validation of a mathematical modeling of single-phase active power filter

Abstract

This work describes the experimental validation of a mathematical modeling of a single-phase PWM active power filter, previously proposed. This model has been developed using the PWM switch technique, created by Vorperian. Laboratorial tests have been developed to verify the validity of several proposed relationships like static gain, line-to-output and control-to-output transfer functions, using tests like step response and frequency response. Due to the narrow agreement between experimental and simulated results, the authors believe the functions developed can be widely employed to describe the system behavior, as well they can be used as support to various control strategies propositions.
