In this paper, a three-phase shunt active power filter (SAPF) is introduced for compensation of harmonic currents caused by non-linear loads in the distributed power system. A SAPF is a power electronic device which has been developed to improve power quality. The current control of shunt power filters is critical since poor control can reinforce existing harmonic problems. Various control strategies have been proposed by many researchers. In this paper, a comparison evaluation of the performance of three current control algorithms, proportional plus resonant (PR), predictive based controller and iterative learning based controller, is presented with an identical system specification. The design procedure and principle of these current control methods are also presented in details. Simulation results show the comparison of transient response, steady state control and performance in the presence of variation of supply impedance between these control techniques.
