Abstract
Power is supplied to a load from either a first power source or a second power source. A transfer switch determines which of the power sources provides the power to the load. A switch control detects a loss in the power provided by a first power source and signals the transfer switch to switch to a second power source. A small energy storage device provides power to the load, during the switch from the first power source to the second power source.
