Abstract :
Present work aims to improve the dynamic response and reliability of Shunt Hybrid Active Filter (SHAF) configuration using improved methods of harmonic detection. A method of introduction of only “positive inductance” through an active filter for mistuned conditions of the passive filter has been presented. “PLL free” scheme of harmonic detection for an uncontrolled rectifier type of non linear load has been studied. Intense simulation studies are carried out using MATLAB/Simulink to validate the functioning of the developed techniques under all conditions of operation. Experimental implementation of the proposed strategy using Digital Signal Processor TMS320F2812 processor is also presented.
