PROBLEM TO BE SOLVED: To provide a power supply device which can suppress an increased loss in a period when contact charging is performed.SOLUTION: An electric path from the junction side of a first and a second switching element 16a, 16b out of both ends of a first electric path L1 to the low potential electric path NL side out of both ends of a second electric path L2 through an output capacitor 24 is defined to be a target electric path. Then, on the first electric path L1, a relay 26 is provided for electrically switching, to an open state, the target electric path to the potential electric path NL side out of both the ends of the second electric path L2, in a period in which power is transmitted between an AC power 50 and a power storage device 40 in a contact power supply mode. |
