Claim 4:
5. The resonant converter of claim 1, wherein the secondary winding comprises: a first terminal, a second terminal and a center-tapped terminal; and
the plurality of secondary switches comprises: a first switch and a second switch;
wherein a first terminal of the first switch is coupled to the first terminal of the secondary winding;
a first terminal of the second switch is coupled to the second terminal of the secondary winding, a second terminal of the second switch is coupled to the second terminal of the first switch;
wherein the second terminal of the first switch is coupled to a first output terminal of the resonant converter and the center-tapped terminal is coupled to a second output terminal of the resonant converter, and the control circuit is configured to control the second switch to be turned on during the first time interval, such that the secondary winding is clamped by the preset voltage, the current of the resonant network is increased in the first flowing direction and the output current is increased in the second flowing direction; or
the second terminal of the first switch is coupled to the second output terminal of the resonant converter and the center-tapped terminal is coupled to the first output terminal of the resonant converter, and the control circuit is configured to control the first switch to be turned on during the first time interval, such that the secondary winding is clamped by the preset voltage, the current of the resonant network is increased in the first flowing direction and the output current is increased in the second flowing direction.
