To provide a bi-directional DC-DC converter for achieving high efficiency, by reducing the recovery of a diode, even at electric power regeration.
The bi-directional DC-DC converter has: a first series circuit, connected to both ends of a first DC power source Vi and consisting of a first winding 1a of a first reactor LT and a first switch Tr1; a second series circuit, connected to both ends of the first switch and consisting of a second winding 1b of the first reactor, a second reactor Lr, a second switch Tr2, a third switch Tr3, and a second DC power source Vo; a third series circuit, connected to both the ends of the first switch and consisting of a fourth switch Tr4 and the second DC power source Vo; and a control circuit 10 for turning on/off the switches, and thereby carrying out step-up and step-down operations between the first and second DC power sources.
