Abstract

The invention provides a bidirectional DC-DC converter and a control method thereof. The bidirectional DC-DC converter comprises a full-bridge converter or a push-pull converter including a rechargeable battery and a transformer, a first winding, a second winding, a controllable one-way conductive device, a rectification filter circuit, a first capacitor, a second capacitor, a first switch tube, a second switch tube and a switch device, wherein the first capacitor and the second capacitor are connected; and the first switch tube and the second switch tube are connected. The switch device is used for making the rectification filter circuit, the first capacitor and the second capacitor form a discharging path in a discharging mode and making the first capacitor, the second capacitor, the first switch tube and the second switch tube form a half-bridge inverter capable of charging the rechargeable battery in a charging mode. Cost of the bidirectional DC-DC converter is low.
