  • Buck Circuit, Buck Apparatus, and Circuit Control Method
    Publication number: 20230106017
    Abstract: The buck circuit includes a first switch component, a second switch component, a first freewheeling component, a second freewheeling component, an inductor, a first capacitor, and an over voltage protection OVP module. The first switch component and the first freewheeling component constitute a bridge arm. A first end of the inductor is connected to a midpoint of the bridge arm, and a second end of the inductor is connected to the second switch component. A first end of the second freewheeling component is connected to the second end of the inductor. A first end of the first capacitor is connected to the second switch component. The first capacitor is connected in parallel to the OVP module and a load of the buck circuit. The OVP module detects an output voltage of the buck circuit, and the output voltage of the buck circuit is an input voltage of the load.
