A repetitive control strategy of AC electronic load with energy recycling

The AC electronic load with energy recycling is a new type of test equipment, which can simulate a variety of load characteristics, and test energy can be feedback to the utility power system with little loss and high power factor. Compared to traditional load device, usually more than 80% energy would be saved. It is energy-saving, environment-friendly and convenient in use, and has wide prospect of applications. In this paper, the characteristic of AC electronic load with energy recycling and active power balance of system are introduced, the key technology of AC electronic load is current characteristics simulation, for the requirements of simulating accuracy, A repetitive control strategy of AC electronic load with energy recycling is studied, and repetitive Control of load simulator is analyzed. Simulation based on the MATLAB / Simulink is done, theoretical analysis and simulation results show that the input current precision of load simulator is greatly improved, and then the precision of load simulation.
