Abstract: Parallel active power filter is introduced as the main filter for harmonic currents. The use of Series Active Power Filter for filtering the harmonics of the voltage is also discussed. The passive filters are used also for elimination of harmonic currents and voltages. The use of hybrid filters composed of parallel active power filter with passive filters, or series active power filter with passive filters is applied and studied. Different studied filters and topologies are implemented in MATLAB\Similink. Simulation results are tabulated and discussed. A comparison between the results obtained in this work and other works in literature is carried out and discussed.
Keywords: Series Active Filter, Shunt Passive Filters, Reactive Power, Power Quality Improvement.
