Popis: In this paper, considering the problem of control the full bridge shunt active power filter operating with nonlinear loads. The main control objectives are: (i) compensation of harmonics current and the reactive power caused by the nonlinear load in order to ensure a perfect power factor correction (PFC) at the point of common coupling (PCC); (ii) regulation the DC voltage of inverter. A nonlinear control strategy is proposed to achieve the main objectives taking into account of grid impedance, and of all non negligible parameters of circuit. The inner-loop control is designed, using the Lyapunov technique, to cope with the compensation issue. The outer-loop control ensures the DC voltage regulation of inverter. The control performances are analyzed using the averaging theory. Simulation results show the achievement of above objectives and also the effectiveness of the proposed control.
