Studyand Comprisonof NovelHybrid Active Power FilterTopologies

some problems such as harmonics, flickr, unbalance and low power factorraises on the power grid because large, non-linear, and time variableLoadsIncreasingthat affecting network power quality. many solutions including passive filters, active filters and hybrid filters for different purposes are suggested for overcome these problems. recent research has been carried out on novel Hybrid filter designs,Due to the dynamic problems of passive and active filters. The purpose of this paper is to introduce and review the new Hybrid Filter structures and compare them in terms of different functions in the power grid.In this study new design of hybrid filter including reactive power static compensator coupling with the Active Power Filter (SVC-HAPF)can better performance in the power system of other structure.
