Title:
UNIVERSAL UNINTERRUPTIBLE POWER SUPPLY INPUT CIRCUITRY AND METHODS FOR CONFIGURING SAME
Document Type and Number:
WIPO Patent Application WO2003073582
Kind Code:
A3
Abstract:
Systems and methods of universal uninterruptible power supply (UPS) input circuitry are provided. The input circuitry of the present invention enables a UPS system to simply connect and operate in conjunction with any suitable backup power system. In particular, once a user indicates what backup system is attached to the input circuitry, a software unit automatically configures the input circuitry to operate with the coupled backup system. Once configured, the software unit may control portions of the input circuitry such that power is continuously provided to a load. For example, once a user indicates that a flywheel based backup system is attached, the software unit may instruct the input circuitry to maintain a predetermined flywheel speed (e.g., RPM) to ensure that the system is in constant ready state to deliver backup power.
