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 switch bridge arm and a capacitor bridge arm. The switch bridge arm includes four switches serially connected. A node between the first and second switches is connected to the first secondary terminal, a node between the third and fourth switches is connected to the second secondary terminal, and a node between the second and third switches is connected between two capacitors of the capacitor bridge arm. In two consecutive periods of the first voltage, the first and fourth switches are in an on state for a preset time length after two falling edges respectively, and the second and third switches are in the on state for the preset time length after two rising edges respectively.
