  • Publication number: 20260048664
    Abstract: A power supply apparatus is provided. The apparatus includes a first converter configured to convert a voltage of power supplied from a power supply source into a first voltage, a first power distributor configured to distribute a current of the first voltage to first voltage loads, and a redundant power system configured to supply power to the first power distributor. The first power distributor includes a first switch configured to switch on or off an output when a current output to the first voltage loads is greater than or equal to a first reference value.

  • Patent number: 9242570
    Abstract: A charging system for a hybrid vehicle which prevents a super capacitor from being reverse charged. In the illustrative charging system a DC-DC converter is connected to the inverter and configured to receive the DC electricity from the inverter and drop voltage. A battery is configured to receive the DC electricity from the DC-DC converter and to be charged by the DC electricity. Finally, a means for preventing reverse charging is mounted on a path between the super capacitor and the battery and is configured to prevent energy from flowing from the battery to the super capacitor.
