  • Patent number: 6509712
    Abstract: A regulating circuit that is coupled to a bus voltage and bus voltage return includes a solar array and a bus voltage limiting circuit electrically coupling the bus to the solar array. A battery is coupled to a battery discharge circuit and a battery charge circuit. The battery discharge circuit and the battery charge circuits are also coupled to the bus. A master bus regulator generates a voltage control signal. The control signal is coupled to the bus voltage limiting circuit, the battery discharge circuit, and the battery charge circuit. The voltage control signal is generated in response to the bus voltage.
