Abstract：The design in this paper used PWM converter instead of diode rectifier, which not only reduced the harmonic pollution to the grid but also can realized two-way flow of energy. Double closed loop control of voltage and current ensures the stability of DC voltage and the tracking of AC current to the voltage. The inverter adopts current forecast control, which is a fixed switching frequency control method in direct current control. The current loop adopted the proportional adjustment to improved the current response. Voltage feedback loop using PI control of voltage RMS to ensure the stable and reliable control of the inverter’s output voltage. The output voltage of inverter is compensating voltage. It is series with the voltage stabilizer input voltage to obtain the output voltage. Using the Simulink, the design of power supply can be simulated. Finally the design results are verified by experiments.
