Abstract

See full text

A method and apparatus for providing uninterrupted power during transitions between a primary power source and a standby power generator. The method and apparatus includes determining one of a power failure condition and a power return condition of the primary power source, transitioning between the primary power source and the standby power generator, and providing power to a load during the transition, the power being supplied by an uninterruptable power supply (UPS) having a capacitor supplied voltage.
