ABSTRACT Uninterruptible power supplies (UPS) are used to provide power when regular utility power is unavailable. Although they are commonly used for providing power in remote locations or emergencies, this is not because they are the same as auxiliary power units, emergency power units or standby generators. Unlike the aforementioned power... Continue Reading
