Abstract
In a DAB circuit including a first bridge and a second bridge, a boost circuit is shared by connecting reactors between a storage battery and the first bridge. In each leg of the first bridge, in order to increase an absolute value of a reactor current, an ON period of one switching element of a switching element on a high voltage side and a switching element on a low voltage side is provided, and then, an ON period of the other switching element is provided. An ON period length of the one switching element is set according to a control command value of a DC voltage input to the first bridge. An ON period length of the other switching element is set to a time length until an absolute value of the reactor current that has increased during the ON period of the one switching element returns to zero.
