Thesis Abstract
The general objective of the system is to provide efficiency in the use of power suppliances by ensuring continuous availability of power supply in the absence of NEPA. Uninterruptability of the system made it possible to eliminate all suspense arising from NEPA outage during the execution of an important and urgent assignment requiring
The use of power especially with computer PC system. The fundamentals purpose of a UPS is to provide an interrupted source of power for the equipment it protects.
For better production of the system it is advisable to operate the system of a fully charged condition of the battery. Also the problem due to excessive heating could be eliminated by the use of a hat sink with a thick and a large surface area for sufficient absorption of heat. This project is rated 200W of 220V and 50H2. It is expected at all condition favourable to carry load of higher power factor of the approximation of the power stated. Loads of low power factor are always not helpful overloading is not potent to provide zero changeover time and has audio helper which indicates mains fail and battery discharge. It provides 100% protection against live noise, swages all radio frequency interference.
