Construction Of Uninterruptible Power Supply

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 sources, UPS provides an immediate and continuous supply of power to a device, hence protecting it from power interruption and allowing time for auxiliary or emergency powers, to kick in equipment to be safely shut down or utility power restored.
The major aim of this was to design a system which will be able to convert battery voltage(12v) to 220v, which is equivalent to wall outlet and secondly able to charge the battery.
The chapter one of this work, gives the over-view of UPS, it’s importance, uses, and application and some of its special features like its ability to correct frequency instability and many more.
Secondly, this work dealt with all components used in the construction of the device, there working condition and uses. Some basic abstract phenomenon were also treated like wave forms and electronic switching.
The chapter three, basically dealt on all electrical measuring instrument used in and on the device, how they are used, why and where.
The fourth chapter explains how the components where assembled into section and the sectional connection used to form the device.
The last chapter is a simple conclusion with honest recommendation.

CHAPTER ONE - [ Total Page(s): 3 ]Inverters allow the user to
provide AC power in areas where only batteries can be made available,
allowing portability and freeing the user of long power cords. However,
most UPS units are also capable in varying degrees of correcting common
utility power problems like:1. Power failure: defined as a total loss of input voltage.2. Surge: defined as a momentary or sustained increase in the mains voltage.3. Sag: defined as a moment ... Continue reading---
