Dynamic behavior with comparative study of the parallel active filter commande

Abstract

The aim of this article relates to the comparison between two strategies for identifying harmonic currents, namely the instantaneous active and reactive power method and the instantaneous currents method, faced with a dynamic non-linear load. This work particularly concerns the study by digital simulation of a parallel active filter intended to filter the harmonic currents generated by a non-linear load and to compensate for reactive energy. Our study focuses on the identification of harmonics and inverter control. The step of identifying harmonic currents is fundamental in the filtering process.
