1. A bidirectional DC/DC converter, comprising:
a first terminal circuit;
a transformer comprising a first winding and a second winding, wherein the first terminal circuit is coupled to the first winding;
a second terminal circuit; and
a reset circuit, wherein the second terminal circuit and the reset circuit are coupled to the second winding;
wherein when the bidirectional DC/DC converter is in a first working state, the first terminal circuit is configured to transmit a first alternating current to the second terminal circuit through the first winding and the second winding, the second terminal circuit is configured to convert the first alternating current into a first direct current, and the reset circuit is in a broken state;
wherein in a first time period in which the bidirectional DC/DC converter is in a second working state, the second terminal circuit is configured to transmit a second alternating current to the first terminal circuit through the second winding and the first winding, and the first terminal circuit is configured to convert the second alternating current into a second direct current; and
wherein in a second time period in which the bidirectional DC/DC converter is in the second working state, the reset circuit is in a conducted state, the reset circuit is configured to reset the second winding, and the second terminal circuit is configured to stop transmitting the second alternating current to the first terminal circuit.
