The present invention provides a bi-directional DC/DC converter and a control method thereof. The bi-directional DC/DC converter comprises a push-pull circuit, a chargeable and dischargeable device, a transformer, a half bridge circuit, a rectifying and filtering circuit and a first switch. The primary side of the transformer is connected to an output of the push-pull circuit. The output of the rectifying and filtering circuit is connected across a bridge arm of the half bridge circuit. The first switch is configured to connect the secondary side of the transformer to an input of the rectifying and filtering circuit, or to connect a part of windings of the secondary side of the transformer to an output of the half bridge circuit while disconnecting the part of windings of the secondary side of the transformer from two terminals of the input of the rectifying and filtering circuit. The bi-directional DC/DC converter of the present invention has fewer components and is low in cost.
