Abstract
A fully regulated multiple source power bus subsystem for a satellite having at least a solar panel array and a battery providing unregulated sources of electrical power. The battery and solar panel array are connected to one or more multiple source bus regulators to produce a fully regulated bus output at one or more preselected voltages. Each multiple source bus regulator automatically switches between the battery and solar panel array and may produce either a positive or a negative bus voltage. A battery charge controller controls the charging of the battery when the output voltage of the solar panel array is greater than the output voltage of the battery.
