[0032]Such asfigure 1 As shown, in the topology of the present invention, the back-to-back converter intermediate DC capacitor side is connected in parallel to compensate for the lack of power of the load voltage, and the back-to-back converter connects the output voltage in the power supply line by isolating the transformer. Taking the compensation load voltage tubing, the other end is connected to the inductive filter transformer filter wave winding for back to back the backbrew the charging and load of the battery pack, the topology is filtered in the induction filter transformer. The passive filter reactive power compensation branch in parallel in the winding is reduced to reducing the reactive filter compensation capacity requirements of the active backrest. The entire device fully utilizes the advantages of the induction filter transformer, and incorporates the energy storage device to respond to the electromagnetic potential of the electromagnetic potential of the electromagn...
