Design of an Uninterruptible Power Supply ( UPS )

Abstract

An uninterruptible power supply (UPS) is an electrical device which convert the electrical current from alternative current into direct current to charge the batters until the power is on, and when the power is off it start to covert the direct current continuosly. This project will introduce the basic requirement of uninterruptible power supply design , and will show a single phase uninterruptible power supply work will be implemented.
