    • 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 the direct current to charge the standby battery and to produce a “clean” alternating current by passing through an inverter and filter system. The output produced is free of sags of services in the line voltage, frequency variation, spikes and transients.

    • CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONE1.0            INTRODUCTIONA DC-AC Inverter is basically a device which converts direct to a sinusoidal current. There are different ways of doing this conversion to achieve better performance and reliable system.. This system is designed to generate 50Hz sinusoidal and 220volts alternating current and a total power of 200watts to provide power to sensitive equipment like computer, communication equipment, and/or to provide emergency light and power to some es ...
