Document Type and Number:
WIPO Patent Application WO/2012/002530
Kind Code:
A1
Abstract:
Provided is a DC-DC converter that comprises a control unit for conducting switching control, and supplies power from a storage battery to DC loads connected to a DC bus with the switching control. The control unit is configured such that, upon detecting that the DC bus voltage has become equal to or less than a prescribed voltage when the DC-DC converter is in stopped state, the control unit starts switching control wherein the pulse width of the switching becomes gradually wider, and after detecting that an output current of the DC-DC converter has started flowing, conducts switching control with the pulse width thereof in accordance with a preset output voltage.
