Comparative Study between Different Controllers used in Three-phase Four-wire Shunt Active Filter

Adaptive Hysteresis Current Control of Shunt Active Filter for Three Phase Four-wire System

In a balanced three phase system, only harmonics of positive sequence(7 th , 13 th ,..etc) and negative sequence (5 th , 11 th ,…etc) are produced. However, the harmonic currents produced by single phase non-linear loads like switch-mode power supplies in computer which are connected between phase to neutral injects third order zero sequence harmonics (3 rd ,9 th ,15 th …etc) (Mehmet et al 2008...

Review on Shunt Active Power Filter for Three Phase Four Wire System

This review provides a survey of shunt active power filter based on inverter in three phase four wire system. These topologies are applied to solve problem due to non linear load in power system network such as a power quality issue, reactive power compensation and harmonic current suppression. In making a review it should be noted that this paper will not attempt to give an all encompassing re...

A Comparative Performance Analysis of Four Control Algorithms for a Three Phase Shunt Active Power Filter

Shunt Active Power Filters (SAPFs) represent the most important and widely used filter in industrial purposes due to the fact that, they not only eliminate the harmonic current with a neglected amount of active fundamental current supplied to compensate system losses, but also they are suitable for a wide range of power ratings. One of the key issues for a proper implementation of an active fil...

Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

Comparative Analysis between PI and Fuzzy Controllers for Dc Voltage Control of Unbalanced 4 Wire Shunt Active Power Filter

This research proposes a shunt active power filter (SAPF) for harmonics mitigation in order to improve power quality of the electrical network. The reference harmonic current extraction technique used was based on DQ0 power theory under unbalanced non-linear loads conditions for four wire-installed systems. The DC-link voltage plays an important role in SAPF design to guarantee both steady high...
