Abstract :
Two shunt active power filter configurations are analyzed in this paper in order to define new control methods characterized by simple control algorithms and minimum voltage and current transducer requirements. The transfer functions for the two control schemes are determined and analyzed to emphasize the active filter behavior in both steady-state and transient conditions. The performance obtained by the proposed control schemes is similar to that of standard solutions. The experimental results substantially confirm the numerical results obtained by Simulink of Matlab
