Single phase half bridge inverter for shunt active power filter: article

This paper describes implementation of half bridge inverter as active power filter to compensate the harmonic current due to the non-linear loads to get THD less than 5% as suitable to the IEEE519-1992 standard. The active power filter consists of a half-bridge inverter, which reduces the number of switch used, compare to H-Bridge inverter. The proposed system is connected in parallel with load and at normal condition; it gives appropriate compensation to solve problems of current displacement and harmonic. Bridge rectifier is used which emulates the non-linear load characteristic. Simulation completed by using MATLAB-Simulink simulation package Simulation and experimental result were presented to verify proposed system.
