Elimination of Harmonics in Power System Using FFT analysis

Abstract: The electronic circuits such as inverters, choppers, cyclo-converters, SMPS used by industrial and domestic purposes are non-linear in nature. Due to the non-linearity effects the problems such as heating, equipment damages, EMI related problems in power system. The harmonic filter is the best solution for eliminating the harmonics caused by the non-linear loads.
