A series resonant converter includes a switching circuit, a resonant tank, a transformer and a rectifier circuit. The switch circuit has a power supply connected to the primary side upper bridge switch and the primary side lower bridge switch, which are configured to control the input voltage and the input current of the power supply. The resonant tank is coupled to the switch circuit and includes a resonant inductor, a resonant capacitor, and a magnetizing inductor connected in series. The transformer is coupled to the resonant tank and includes a core, a primary winding, and at least four groups of secondary windings. The core has a center column, the primary winding is wound on the center column, and at least four secondary windings are wound on the center column. The number of equivalent windings added by the at least four groups of secondary windings is 1.
