摘要

The UPS (uninterruptible power supplies) are essential power infrastructure components of systems designed for critical application, including data centers. High availability achievement is a very important factor related to UPS performance, consequently to proper critical application functionality. Generally, UPS have a limited input voltage window, referring to the nominal input voltage value. Goal of this paper is to prove larger voltage window, without affecting normal UPS operation. Larger window will result on less commutation, backup and normal mode reduction, and consequently duty time of batteries reduction, too. Thus, under these conditions, it is to be expected availability improvement. The stabilizing node model, applied at UPS's control part through this paper is presented. UPS's behavior with an implemented stabilizing node is observed at few sites. In order to analyze and conclude about UPS's performance under these technical conditions, simulation results are further presented.
