Relying on information digital technology, a new type of double loop grid current control method for single phase double Buck grid connected inverter is proposed. The intelligent electric frequency intensity control technology （VNDS）, wave protection algorithm （BVUS） and dynamic pulse width control technology（BDZT）are used to solve the problems existing in the traditional double Buck inverter current control method. The simulation results show that the proposed method is better than the traditional double loop current control method of single phase double Buck grid-connected inverter, and the test values are better than that of the traditional dual Buck grid-connected inverter current control method.
