With the rapid development of electric vehicles, the charging station has become the focus of the development of the automobile industry and the energy industry. However, the overall performance of the existing charging stations is average, the circuit is unstable, and generally adopts The voltage of the power supply is boosted to the charging voltage of the electric vehicle, and then the power battery of the electric vehicle is charged by the constant current and constant voltage control circuit, which generally has the following defects: the efficiency of the power boost circuit topology is relatively low, which wastes energy; The small signal transfer function of the boost circuit topology has a right-half-plane zero point, the power is not easy to increase, and the reliability and safety performance are poor; the isolation application of the power boost circuit topology is more difficult and costly
