When a calculated duty obtained through a feedback operation is within a specific range, a duty outside the specific range is adopted without increasing a difference from the operation result. When a calculated duty obtained through a feedback operation is within a modification target range, an arithmetic unit of a DC-DC converter selects a predetermined value as a substitute and determines a usage duty based on the substitute. Whenever the calculated duty within the modification target range is obtained, the arithmetic unit updates a cumulative value by accumulating a value indicating a difference between the usage duty based on the substitute and the calculated duty. When a predetermined condition is met, the arithmetic unit modifies the usage duty by performing addition or subtraction on a part or whole of the cumulative value, and updates the cumulative value by subtracting the value used for modifying the usage duty.
