CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
The
quest to convert D.C. power to A.C power to run some essential
appliances results due to erratic power supply being experience.
Although, between the 19th century to mid 20th century, D.C. to AC power
conversion was accomplished using rotary converters or motor generator
set (M-G set). In early 20th century, vacuum tubes and gas filled tubes
began to be used as switches in inverter circuit. In contrast the early
A.C. to D.C. converters used an induction or synchronous a.c motor
directly connected to a generator (dynomo) so that the generator’s
commutator reverses its connections at exactly the right moments to
produce D.C.
Considering the above reasons, for the study, many
electrical equipments have either developed a problem or even stopped
working entirely. As a result, many businesses have been crippled
thereby affecting the economy as a whole with respect to Nigeria.
Again,
power disturbances occurrence are on increase resulting to high voltage
spikes and momentary voltage drops, this often affect the performance
of sensitive electrical electronics equipment.
Unincessant supply of electric power can not be over-
emphasized
in Nigeria presently, this has become the order of the day and many
Nigerians now presume power outages as a normal routine in the power
sector. There are factors responsible for this ugly situation such as
natural disasters, vandalism, maintainability, sustainability,
inadequacy and lack of vision by the political leaders to invest
adequately in power sector, also absence of replacement policy resulting
in absolute abandon of electrical equipment or project, unsustainable
human capacity and inadequate and remuneration system to motivate human
resources term to perform well on their course.
The progress made
some decades ago in developing alternate source of energy has proved
that independent power system are not only possible but as well
practical. A wide variety of generating equipment is now available to
allow individuals take advantage of any prefer renewable resources of
energy. Most of these systems produce only direct current (DC) for a
number of reasons and at low voltages. However, it is well known that
the alternating current is the greatest and most useful form of current
being generated by the power grid due to its advantages over direct
current. Thus, most of the appliances and equipment are built using a.c.
input source.
Therefore, there arises the need for converting direct
current (DC) to an alternating current (A.C.) having a constant
frequency. This process is known as inverting.

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---
