초록 ▼

An UPS (uninterruptible power system) includes an UPS power conditioning unit that provides conditioned AC power to a critical load. The UPS power conditioning unit includes a variable speed drive that operates in response to AC utility power or to a standby DC input by providing a motor drive signal. The UPS power conditioning unit further includes a motor-generator that operates in response to the motor drive output by providing the conditioned AC power to the critical load. In response to an outage in the utility AC power, standby DC power is provided by a standby DC power source that includes a variable speed drive and a flywheel motor-generator connected to the variable speed drive. Both the UPS power conditioning unit and the standby DC power source are initially operated in response to the utility AC power, the flywheel motor-generator storing kinetic energy in a rotating flywheel. When an outage occurs, the rotating flywheel continues to operate the flywheel motor-generator of the standby DC power source, causing the production of AC power which is rectified and provided as standby DC power to operate the variable speed drive of the UPS power conditioning unit until either the utility AC power outage is over or a standby emergency generator is brought on line.

대표청구항 ▼

An uninterruptible power system, including: a first connection for receiving utility AC power; an uninterruptible power system (UPS) power conditioning unit connected to the first connection; a critical load connection on the UPS power conditioning unit for providing conditioned AC power to a critical load; a standby DC power connection on the UPS power conditioning unit; a standby DC power source coupled to the standby DC power connection for providing standby DC power to drive the UPS power conditioning unit during interruptions in utility AC power; a first variable speed drive in the standby DC power source with a first motor driven output; a flywheel-motor generator in the standby power source for generating AC power; the flywheel-motor generator having a motor drive input connected to the first motor drive output; and a rectifier connected to the flywheel motor-generator and to the standby power connection for producing the standby DC power by rectifying the AC power generated by the flywheel motor-generator.
