This paper presents a single-phase active power filter for harmonic compensation which is consists of a series active power filter and a shunt passive filter. The active filter connected in series to a source acts as a harmonic isolator between the source and load whereas the shunt passive filter is connected in parallel with a load and suppresses the harmonic current produced by the load. The PSpice®, Matlab/Simulink® and MAX PLUS II® softwares are used for simulation and hardware implementation. From the simulation and experimental results it is confirmed that the filter topology is capable of compensating the load current and voltage harmonic distortion within the stipulated limits laid down by the international standard.
