NON LINEAR CONTROL FOR SHUNT ACTIVE POWER FILTER BY USING INSTANTANEOUS REACTIVE POWER STRATEGY

Abstract

This paper presents a simulation study of Feed back lenearised Controller of the DC bus voltage and currents of three phase shunt Active Power Filter (APF).The Feed back controller is introduced to improve tracking performance characteristics, power quality and minimized consumption of the reactive power. The algorithm used to identify the reference currents is based on the Self Tuning Filter (STF) for application of The method of instantaneous active and reactive power
