  • Battery charger with high frequency transformer
    Patent number: 8188708
    Abstract: A battery-charging system includes a power supply having a high-frequency transformer and is configured to deliver a battery charging power to charge at least one battery. The high-frequency transformer has a bobbin including an elongated top and bottom surfaces and first and second substantially semi-circular end surfaces connecting the top surface with the bottom surface to form an elongated first coil winding surface having a central axis. A first coil is wound around the first coil winding surface, and a second coil is magnetically coupled to the first coil and wound thereto.
    Type: Grant

  • Battery charger with wind tunnel cooling
    Patent number: 7868588
    Abstract: A battery charging system which includes a main housing with a main chamber defined by a base, an end panel mounted on each end of the base, and a cover enclosing the end panels. At least one battery charging connector is connected to the housing. A power supply is connected to the at least one battery charging connector, where the power supply provides a battery charging electrical power to the at least one battery charging connector. The power supply has at least one heat generating electrical device. A tunnel is formed at least partially within the main chamber and extends between the end panels in the main chamber. At least one heat generating electrical device at least partially extends into the tunnel to be exposed to air in the tunnel to cool the heat generating electrical device.
