Abstract
In first power transmission in which power is transmitted from a first DC power source to a second DC power source, a control circuit performs on/off drive control of a positive electrode-side switching element and a negative electrode-side switching element in a first bridge circuit and a second bridge circuit and stops on/off drive of a positive electrode-side switching element and a negative electrode-side switching element in a third bridge. For a positive electrode-side switching element and a negative electrode-side switching element of a fourth bridge circuit, when a first power transmission amount by the first power transmission is greater than a predetermined first reference value, the control circuit performs on/off drive control, whereas when the first power transmission amount is smaller than the first reference value, the control circuit stops on/off drive.
