Simulation and comparison between hybrid active power filter and shunt active power filter

The shunt active power filters (SAPFs) and hybrid active power filter (HAPF) is used for practical solution to solve the electric power quality, (EPQ) issues. The emerging power-electronic devices and the new developments in digital signal processing (DSP), have made possible its practical use. The active power filters can compensate the nonlinear load current of electrical systems: harmonics, reactive power, imbalances, etc. In this paper simulation and comparison between shunt active power filter and hybrid combination of shunt active power filter and shunt passive power filter is presented. FFT (Fast Fourier Transform) analysis and waveforms are presented for both filters. The superior performance of hybrid active power filter is also presented.
