Abstract
A DC-DC converter includes a bridge circuit, a resonant tank circuit coupled to an output of the bridge circuit; a rectifier circuit having an input coupled to the resonant tank circuit and an output, and an output filter coupled to the output of the rectifier circuit. A controller is coupled to the bridge circuit, the resonant tank circuit and the output of the DC-DC converter. The controller is configured to control a switching frequency of the bridge circuit to operate the DC-DC converter as a boost converter and a buck converter. When the DC-DC converter is operating as a buck converter, the controller controls the rectifier circuit to selectively block energy transfer from the rectifier circuit to the converter output based upon an output current of the DC-DC converter being greater than current demand thereof, thereby reducing output current of the DC-DC converter and extending an operating range thereof.
