Uninterruptible Power Supply (UPS) is increasingly becoming popular as a means of providing conditioned and uninterrupted power supply to sensitive and non-sensitive loads at critical and non-critical times.Sensitive modern equipment with very low tolerance for power fluctuation and failures are on the increase due to advancement in science and technology, theseequipment however require power backed up if they are to perform optimally. This study focuses on modification of the UPS in order to extend its running time.A used and dumped UPS working at a back-up time of between 0 to 10mins was modified to accommodate two, 75AH Lead acid batteries, using 1400VA Zinox UPS. An extended backup time of between 2hrs to 8hrs on the same UPS using Lead Acid/Deep Cycle batteries was achieved which at the same time operating within a very low budget.

Uninterruptible Power

The major purpose of uninterruptible power supply (UPS) systems is to supply regulated sinusoidal voltage at constant frequency and amplitude. UPS systems are gaining much popularity as a means of providing clean and continuous electricity to critical loads during any disturbances in main grid. Modern equipment is sensitive to power fluctuation and requires back up power supply for optimal performance. This chapter introduces a set of possible solutions so that uninterrupted power supply can be provided to emergency feeders and critical loads such as hospitals and communication systems. Different network configurations can be applied to micro-grid system for obtaining an uninterrupted power supply. Various hybrid energy and modern UPS systems for micro-grid along with their control techniques have been elucidated. A comparative assessment of all UPS technologies on the basis of cost, performance, and efficiency of the system has been presented.
