Patent abstract

There is a disadvantage that a loss generated in a charging apparatus becomes large. It is determined whether a link voltage Vo is equal to or higher than a predetermined value Va. If the link voltage Vo is less than the predetermined value Va, a control unit activates a DC-DC converter in a boosting operation. That is, by turning on/off the switching element, the voltage boosted from the storage battery is supplied to the link voltage Vo. The control unit determines whether the link voltage Vo is equal to or higher than the predetermined value Va. If the link voltage Vo is less than the predetermined value Va, the operation is continued. When the link voltage Vo rises due to the boosting operation of the DC-DC converter and becomes equal to or higher than the predetermined value Va, the boosting operation of the DC-DC converter is stopped.
