The present application provides a bipolar-output resonant DC-DC converter, relating to the field of power electronics. An output terminal of a control circuit is respectively connected to control terminals of an input half-bridge and an output half-bridge. An input terminal of the input half-bridge receives an input signal; a first output terminal of the input half-bridge is connected to one end of a resonant network, and a second output terminal of the input half-bridge is grounded. The other end of the resonant network is connected to an input terminal of the output half-bridge. Both a first output terminal and a second output terminal of the output half-bridge are connected to an external load, and are respectively configured to output a positive-polarity voltage and a negative-polarity voltage. The resonant network is configured to transfer energy between the input half-bridge and the output half-bridge. Under control signals output by the control circuit, the input half-bridge and the output half-bridge are cyclically turned on or off within a predetermined operating period, thereby enabling bidirectional energy transfer through the resonant network. The present application can improve the reliability, conversion efficiency, and power density of a bipolar-output power supply.
