Abstract

See full text

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 two clamping switches, a switch bridge arm, and a capacitor bridge arm. The switch bridge arm includes four switches serially connected. The two clamping switches are connected in series between a node between the first and second switches and a node 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. A node between the two clamping switches is connected between the two output capacitors. The second and third switches are at least in an on state for a preset time length after falling and rising edges in a period of the first voltage respectively.
