Comparative Analysis on Shunt Active Power Filter Based PQ Control Strategy Using HCC, SPWM and SVPWM Switching Signal Generation Techniques

The most important part of the active power filters is the generation of the switching signals for gate inverters. In this paper the techniques which are considered for comparative study are Hysteresis Current Control (HCC), Sinusoidal Pulse Width Modulation (SPWM) and Space Vector Pulse Width Modulation technique. Performance analysis of above three switching signal generation based on percentage (THD) Total Harmonic Distortion. A typical system has been simulated based on instantaneous active and reactive power current control strategy by MATLAB/SIMULINK for showing the performance of the proposed methods.
