1.2 OBJECTIVE OF THE PROJECT
The
purpose of this project is to design and construct a circuit that will
take a 24V dc input from battery and produce a 200VA (AC) output at 200V
– 220V, 50Hz with under voltage and over voltage protection. The study
intends:
i) To design an electrical system that converts d.c. power
to a.c. power to drive various appliances used in the laboratories,
theatres, rural areas etc.
ii) To have a source of generating electricity that has no negative effect on the environment (i.e. no greenhouse effect).
iii) To provide an exposition to the HND students to simple electrical design, analysis and building of circuits.
iv) To provide a noiseless and weightless source of electricity generation.
v)
The study will also serve as a means of impacting practical knowledge
and skills to students, lecturers and other who may wish to acquaint
themselves with the principles of operation of an inverter system.
1.3 THE SCOPE OF STUDY
The
scope of this study is to design and construct of an inverter system
with an output power rating of 1.5KVA, maximum output current rating of
9.09A, and output voltage of 200V a.c. at 50Hz from a 24V dc input. A
few most widely used applications of inverter include running of
computers, microwaves and electrical power tools etc.
The scope of
this project shows how low voltage d.c power supply is used to energized
an inverter circuit. It also show how low a.c. voltage obtain from the
oscillator output is being amplified and step up to a required output
voltage.
1.4 LIMITATION OF THE STUDY
In spite of the construction
of an inverter and its noiseless and pollution free nature unlike other
alternative sources of the generating electricity, there is a need for
charging and recharging the battery from time to time.
The inability
of the circuit to provide a pure sine wave output from gives room for
further improvement. This is because it is quite expensive to design a
pure wave inverter circuit.
Again, lack of financial assistance
incapacitated the project to achieve its accuracy and reliability as
well its appearance (packaging).

ABSRACT - [ Total Page(s): 1 ]This project review the conformability of uninterrupted power supply through the use of inverter. An inverter is a system that converts a direct current to an alternating current. However, inverter is of different categories base on power rating such as 1KVA, 1.5KVA,1.5KVA, 5KVA etc. Moreover, since the invention of inverter, some problem associated with alternative power supply had been drastically reduced. Meanwhile, the problems such as: noise, production of fumes, cost of procurement of oi ... Continue reading---
