ABSTRACT As new ideas unfold and technology become advanced with business increasingly being dependent on technology for their fundamental operation; the need for system availability is of paramount importance. Uninterruptible power supply maintain continuous supply of electric power to certain essential equipment that cannot be shut down unexpectedly. They are generally associated with telecommunication equipment, computer system and other facilities such as airport traffic controls system where even brief commercial ...

ABSTRACT   This uninterruptible power supplies device has the capability of converting from 12volts D.C to 220volts alternating current at the frequency of 50Hz with the help of a step-up transformer. The main importance of this device is its ability to ensure absolute continuity of power to the computerized control system thereby protecting a critical equipment from electrical supply failure. Ups system achieve this by rectifying the mains supply, using ...
