Uninterruptible power supply (UPS) system of 600VA / Siti Morni Jalil

This project is concerned on the development of a '600VA Uninterruptible Power Supply (UPS) System'. The work is based on improvements made on existing UPS manufactured in the industry with the objective of studying existing design and improvements made to be more commercially competitive. Improvements made in this project are emphasized in terms of making the design more compact through the use of double sided PCB arrangement as against the existing single sided PCB. This could later be used for further improvements through continous development. The project begins with a study on the existing UPS sample and comparisons are made in terms of theoritical design requirements; relating to the type of UPS system that exist, major subsystem, its function and operation This follows with descriptive on the implementation of double sided PCB and studies that have been made on eachsubsystem that have been used on the board. Operation procedures and relevant information that should be possesed by any design that are initially obtained. These inculdes the type of system being used , characteristic of the system, the components that were being used, the operation of each major subsystem and protection scheme that have been applied
