ABSTRACT:
A power supply system and method provides for smooth transitions between a utility power, transitory instantaneous power, and backup power in the event of a utility power failure of a utility supplying power to a load. As the utility power weakens due to a failure of the normal utility power supply, a synchronous machine becomes immediately a generator and supplies the required instantaneous power to the load. In order to maintain a constant speed on the synchronous machine, a high speed flywheel rotating faster than the synchronous machine provide kinetic energy that is magnetically coupled to the synchronous machine through an electromagnetic clutch to provide the synchronous machine with the required energy until the utility recovers from its failure. The control means enable smooth transitions by phase synchronization when transiting between utility power, instantaneous power and backup power.
