Aiming at the LCL grid connected inverter link of the rear stage of the energy fed electronic load,the limiting fuzzy PI controller with power function as the quantization factor of the fuzzy control in-put is introduced to control the voltage outer loop,and the passive controller is used as the current inner loop to improve the grid connected performance of the system.The simulation results show that the con-trol method in this paper reduces the overshoot and fluctuation amplitude of the intermediate bus voltage,reduces the harmonic distortion rate of the grid connected current,and improves the overall performance of the system.
