  • Power supply device for supplying power to a load by combining a secondary battery and a capacitor
    Patent number: 9520806
    Abstract: A power supply device for supplying power to a load by combining a secondary battery and a capacitor connected in parallel to the secondary battery includes an insulation type DC-DC converter with a primary coil connected in parallel to the secondary battery and configured to accumulate energy by a current supplied from the secondary battery and a secondary coil connected in series to the capacitor and configured such that an induction current flows therein by the accumulated energy from the primary coil.
    Type: Grant
    Filed: December 4, 2012
    Date of Patent: December 13, 2016
    Assignee: Volvo Truck Corporation
