Provided is a bidirectional DC/DC converter which can control a boost voltage in a wide range. The DC/DC converter includes: three series circuits formed by a first to a sixth switch, each two of which are connected in series between a plus terminal and a minus terminal of a high voltage side; two transformers in which primary windings are connected in series and input terminals of the primary windings are connected to connection points of the switching elements; and a seventh to a tenth switch. The transformers have secondary windings, each of which is divided at the middle point. The middle points are connected to a minus terminal of a low voltage side. Respective terminals of the secondary windings are connected to a plus terminal of the low voltage side by the seventh to the tenth swithes. |
