This　article　presents　a　hybrid　full-bridge　for　high　efficiency　in　a　wide　output　voltage　range,　especially　for　pulsed　output　current　applications.　For　the　conventional　phase-shift　full-bridge　dc-dc　converter,　the　hard　switching　and　circulating　current　lower　the　efficiency　in　the　wide　output　conversion　ratio.　To　improve　the　efficiency　of　the　dc-dc　power　supply　for　the　pulsed　output　current,　a　hybrid　dc-dc　converter　is　proposed.　On　the　primary　side,　two　full　bridges　are　integrated　by　sharing　a　bridge　leg.　The　circuit　on　the　secondary　side　is　a　hybrid　rectifier　stage.　For　the　pulsed　output　current　with　a　constant　load　resistor,　a　single　full　bridge　works　in　a　low　output　current.　For　the　large　output　current,　the　hybrid　two　full　bridges　work　together.　The　circulating　current　in　the　hybrid　working　mode　is　reduced　by　a　blocking　capacitor.　The　converter　is　controlled　by　phase　shift　and　duty　cycle　control.　All　the　switches　work　in　zero-voltage　switching.　A　prototype　is　built　to　verify　the　performance　and　control　strategy　of　the　converter.
