This paper presents a MATLAB/SIMULINK simulation of an active power filter, in which the instantaneous harmonic and reactive compensating currents are desegregated in their different α β space-trajectories, and in their time-domain waveforms of both the abc and the α β system of coordinates. Departing from Akagi's generalized instantaneous reactive power theory, a complete analysis is presented, in which the counter harmonic compensating current injected to the coupling point of the AC main feeding a SIX pulse-controlled three phase AC/DC converter is desegregated in its three component. It is demonstrated, in a selected number of abc and α β oscillograms, and current-space-trajectories that the active filter can compensate either separately or jointly the above mentioned currents.
