A DC/DC converter refers to a device that converts direct current to direct current. The working principle of a DC-DC converter is based on power electronics, which converts input direct current voltage into high-frequency square wave voltage through a combination of switching tubes, inductors, capacitors, and other components. After output rectification and filtering, the required direct current voltage is obtained. This technology has the advantages of high efficiency, wide input voltage range, adjustable output voltage, and fast dynamic response.
