Saduf Shabeer, Ashish Grover, Abdul Hamid Bhat . Shunt Hybrid Power Filter for Harmonic Reduction to Improve Power Quality using PI and Hysteresis Controller. International Journal of Computer Applications. 147, 4 ( Aug 2016), 7-12. DOI=10.5120/ijca2016910968
Shunt hybrid power filter are extensively used for current harmonic elimination and to compensate reactive power for linear/nonlinear loads and to improve input power factor. Hybrid power filter is thus used as practical solution to solve the electric power quality (EOQ) issues. Hybrid filter consists of a shunt active power filter (SAPF) and passive filters .Shunt active power filter operates at a very low switching frequency, thus giving higher conversion efficiency. The combined operation of shunt active power filter and passive filter ensures total harmonic distortion (THD) of source current should be within the permissible limits set by various regulatory agencies ie THD=<5% and supply power factor is near unity. The effectiveness of the hybrid filter has been verified by the extensive simulation results carried out in MATLAB/Simulink and Sim Power System software.
