Abstract

See full text

Provided herein is a relay architecture for selecting between multiple power sources. In one approach, a first relay and first power source are electrically coupled to a first terminal. A second relay and second power source are electrically coupleable to a second terminal and to the first relay. A load is electrically coupled with at least one of the following in the case that a load voltage is below a predetermined threshold: the first terminal, the second terminal, and a third power source, wherein a power supply is provided to the load by the first power source in the case that the first power source is coupled to the first terminal. The power supply is provided to the load by the second power source when the second power source is coupled to the second terminal and the first power source is disconnected from the first terminal.
