Design and Construction of Uninterruptible Power Supply (UPS) System
ABSTRACT
This project presents the design
and construction of Uninterruptible Power Supply (UPS) system with an apparent
power output of 500VA (0.5KVA). This was achieved by the use of transformer,
rectifier, inverter circuit, battery, full wave rectification, change-over
circuit and filtering was implemented by the use of smoothening circuit using
capacitors. We used an inverter that deliver an alternating current (a. c.) of
220V, 50Hz and the output voltage is made to have enough power to drive 4' 4
the load connected to it. The output from the inverter is synchronized in
frequency and magnitude with the external power supply so that at power outage,
the battery back — up inverter then supply power to the load ensuring that the
power supply to the load is uninterrupted. This project provides a clean
dependable supply of alternating current free of surges, frequency variation
and transients and it is also used as back-up for electrical appliances to
maintain a continuous supply of electric power.
