Analysis of Control Strategy for Hybrid Active Power Filter

Abstract

Abstract-The hybrid active power filter is very efficient in filtering harmonics and power factor correction. But its efficiency depends on many factors; including control strategy plays a very important role. Therefore, this paper aims to analyze mathematical model of the hybrid active power filter. On that basis, a comparison between the control strategy according to the load harmonic current and source harmonic current have done. The simulation results have proven to be that: control strategy according to the load harmonic current is more effective the control strategy according to the source harmonic current. This analysis will be the basis of the researches in control of the hybrid active power filter.
