A Novel Harmonics Elimination Method for Three-Phase Industrial Applications

Abstract

There are many ongoing researches in the field of harmonic compensation using active and passive power filters or the combination of the two, which are known as hybrid power filters? These filters can be implemented as series or shunt units. For shunt compensation, the voltage rating of the components is usually higher, and the impedance of the filtering unit should be very high to block the flow of the fundamental harmonic. For the series compensation, the impedance for the fundamental components should be minimal. In order to improve the power quality, many control algorithms have been proposed for automatic and selective harmonic compensation
