Current-Source Shunt Active Power Filter with Periodic-Sampling Modulation Technique

In this paper are presented experimental and simulation results of a developed Current-Source Three-Phase Shunt Active Power Filter compensating the currents of a nonlinear load. The Shunt Active Power Filter controller, described in detail along the paper, relies in the p-q Theory to calculate the reference compensation currents and to regulate the DC-link inductance current. The regulation of the active filter DC-link inductance current is done consuming sinusoidal currents in phase with the system voltages. The performance and the dynamic behavior of the Shunt Active Power Filter using Periodic Sampling Modulation Technique was assessed first through several computer simulations, and then through the analysis of experimental results obtained with a developed laboratory prototype. Thereby, in this paper are presented several obtained results that show the correct operation of a Current-Source Three-Phase Shunt Active Power Filter using the Periodic-Sampling Modulation Technique.
