Description
Summary:Energy regenerative single-phase AC electronic load is a power electronic device that simulates resistive loads and inductive and capacitive loads of arbitrary power factors, and feeds the absorbed energy back to the power grid. The traditional proportional integral control method has low accuracy, slow dynamic response, and cannot achieve static tracking of current. Therefore, a composite control strategy based on fuzzy PI and quasi-PR control is proposed. Fuzzy PI improves the speed and robustness of the controller, and quasi-PR control enables static tracking of current. The designed control method is simulated and verified by Matlab/Simulink. The experimental results show the correctness and effectiveness of the control scheme.
