The invention relates to a switching power supply method and relates to an automatic charging circuit suitable for different electric vehicle battery voltage specifications based on the method. The circuit at least comprises a pulse width regulation and control circuit for controlling pulse width regulation and a high-frequency transformer, and is characterized in that the high-frequency transformer comprises a primary coil winding and a secondary coil winding, and the primary coil winding and the secondary coil winding are wound on a magnetic core and are fixed through a transformer support frame; and the pulse width regulation and control circuit comprises a second controller for detecting the secondary voltage and the load state, a first controller for controlling the primary coil winding to be switched on and off, and a switching tube. According to the switching power supply method, high-frequency transformer windings are reduced, the size of the high-frequency transformer is reduced, and the utilization of non-renewable resources is reduced.

    本发明涉及一种开关电源方法,同时涉及基于这种方法使用于适应不同电动车电池电压规格的自动充电电路,至少包括:控制调脉宽的脉宽调控电路和高频变压器,其特征是:所述的高频变压器包括一个初线线圈绕组和一个次线线圈绕组,初线线圈绕组和次线线圈绕组绕在磁芯上,并通过变压器支撑架固定;所述的脉宽调控电路包括检测次级电压和负载状态的第二控制器,控制初线线圈绕组接通和关闭的第一控制器和开关管。它提供一种减少高频变压器绕组,降低高频变压器体积,减少不可再生资源使用的一种开关电源方法。
