Abstract: An uninterruptible power supply (200) provides improved reliability by supplying temporary standby power to a critical load (104) and startup power to a backup power source (112) from a single energy storag e system (230). In the preferred embodiment, a flywheel energy storage device that produces three-phase AC voltage is used to provid e temporary power to a critical load while a backup power supply, such as a diesel generator set (GENSET) (112), is accelerated to ful l speed. The startup power for the GENSET is also provided from the flywheel energy storage device through a circuit that converts the AC voltage at one level to DC voltage at a lower level (e.g., 12 or 24 volts). Therefore, backup power will be provided from the GENSET unles s a catastrophic failure occurs in the GENSET itself.
