Abstract: This application provides a bidirectional DC/DC converter, a control method thereof, a vehicle power supply system, and a vehicle. The bidirectional DC/DC converter includes a first terminal circuit, a transformer, a second terminal circuit, and a reset circuit, and the transformer includes a first winding and a second winding. The first terminal circuit is coupled to the first winding, and the second terminal circuit and the reset circuit are coupled to the second winding. In a first time period in which the bidirectional DC/DC converter is in a second working state, the second terminal circuit transmits a second alternating current to the first terminal circuit by using the second winding and the first winding; and 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, to reset the second winding. In this case, the second terminal circuit stops transmitting the second alternating current to the first terminal circuit. By implementing this application, bidirectional energy transmission of a DC/DC converter can be implemented.
