Abstract

The present disclosure provides a three-level rectification DC/DC converter including primary and secondary circuits and a resonant tank circuit. A voltage between two primary terminals is a first voltage. The secondary circuit includes a flying capacitor, a switch bridge arm, and a capacitor bridge arm. The switch bridge arm includes four switches serially connected. Two terminals of the flying capacitor are respectively connected between the first and second switches and connected between the third and fourth switches. Two secondary terminals are respectively connected between the second and third switches and connected between two output capacitors of the capacitor bridge arm. In two consecutive periods of the first voltage, the first and second switches are in an on state for a preset time length after two falling edges respectively, and the third and fourth switches are in the on state for the preset time length after two rising edges respectively.
