This　paper　presents　a　hybrid　full-bridge　DC-DC　converter　for　a　wide　output　voltage　range　in　high　efficiency,　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　the　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　the　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.　IEEE
