BIDIRECTIONAL DC/DC CONVERTER AND CONTROL METHOD THEREFOR, AND VEHICLE

WIPO Patent Application WO/2022/160234

A1

Provided are a bidirectional DC/DC converter and a control method therefor, and a vehicle power supply system and a vehicle. The bidirectional DC/DC converter comprises a first terminal circuit, a transformer, a second terminal circuit and a reset circuit, wherein the transformer comprises 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. During 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 means of the second winding and the first winding; and during a second time period in which the bidirectional DC/DC converter is in the second working state, the reset circuit is in a turned-on state and resets the second winding, and at this time, the second terminal circuit stops transmitting the second alternating current to the first terminal circuit. By means of implementing the present application, bidirectional energy transmission of a DC/DC converter can be realized.
