Abstract:
1. A fuel-control system for regulating the administration of power to a controller, comprising: a DC bus for distributing electrical power to various components of the fuel-control system; a primary source of electrical power that supplies the electrical power to the DC bus; an independent backup system that includes a secondary source of electrical power; a controller adapted to consume the electrical power from either the primary source or the secondary source in a mutually exclusive manner; a breaker adapted to selectively isolate the controller and the independent backup system from the DC bus according to signals from the controller, wherein, when a voltage read from the DC bus falls below a predetermined minimum voltage level, the controller causes the breaker to interrupt power-supply capability between the DC bus and the controller, and wherein, when the voltage read from the DC bus overcomes the predetermined minimum voltage level, the controller causes the breaker to restore connectivity between the DC bus and the controller.
