  • Auto charger for system including a high voltage supply and a low voltage supply
    Patent number: 6455951
    Abstract: A power supply system having a simple arrangement of connections between a load connected to a positive terminal of a high voltage battery via a pulse modulation control circuit and to and a positive terminal of a low voltage battery permits loading to be controlled throughout the system without damage or electromagnetic interference. The power supply system can accommodate low voltage loads on the high voltage subsystem to reduce conversion requirements for any DC/DC converter that is included in the power supply system. A charging controller regulates the amount of charge supplied to the high voltage and low voltage batteries.
