Objective: This paper demonstrates the hybrid active power filter (HAPF) implementation in the two-bus system with non-linear loads comprising of inductance, capacitance and the rectifier using intelligent controllers. Methods: Active Power filter (APF) is developed using the point of common coupling (PCC) voltage regulation principle based composite controller. Matlab based implementation using PI, Fuzzy and Adaptive Neuro Fuzzy Inference System (ANFIS) controllers is carried out and the results are tabulated and observed. It is perceived that the Neuro Fuzzy implementation of the HAPF is achieving better results. Findings: A two-bus system with all the three types of loads like rectifier with resistance, inductance and capacitance is considered for the analysis. This paper uses the composite control technique. Improvements: The correction in power factor, Total Harmonic Distortion (THD) improvement and reactive power compensation are used as the measure of the performance in the performance analysis carried out in this paper.
