Abstract
A straightforward approach to suppress three-phase supply current and load voltage distortions is presented. This latter uses the unified power quality conditioner (UPQC) topology made up of a hybrid active power filter (APF) combination based on a series APF, sharing a common DC voltage with a parallel APF, and passive filters. Supply current distortion is introduced by connecting a non-linear load, while load voltage distortion occurs after adding 5th and 7th harmonics to the AC main voltage. The series APF controller forces load voltage to be sinusoidal, whereas parallel APF and passive filters counter harmonic contents from supply current. A model established under Matlab-Simulink software shows the performance of such approach.
