1.2 OBJECTIVES OF THE PROJECT
In this project, a
5KVA D.C. to A.C inverter will be constructed and analyzed. The primary
objective of undertaking this project is for the following reasons:
1.
To design an electrical system capable of producing power from a 12v
D.C. battery that will be used to produce an output of 5KVA 50Hz – 240v
which will be used to drive electrical appliances.
2. The project is also aimed at exposing the HND students to simple electrical design and building electrical circuit.
3.
The project (5KVA, 220 – 240v inverter) will also help the student to
understand the basic principles of operation of an inverter circuit and
its relevance in the society.
4. The project is also aimed at introducing the principle circuit of analysis
1.3 SCOPE OF THE STUDY
The project has been undertaken i.e 5KVA, 220 – 240 volt inverter has four stages or units.
These units includes
i. Supply unit
ii. Inverter unit
iii. Step-up transformer unit
iv. Triggering unit.
The
scope of this project is primarily to show how the low voltage DC power
supplied is used to energize the circuit. It will also show how the
inverter unit convert he low voltage DC into a low voltage AC in form of
square wave. The triggering unit provides the trigging pulse needed by
MOSFET to operate.
1.4 LIMITATION OF THE STUDY
In spite of
the base of construction of an inverter and it’s noiseless and pollution
free native unlike other alternative source of the generating
electricity, there is a need for charging and recharging the battery
form time to time.
Also the use of the bulky transformer instead of
copper transformer which is lighter and smaller in size, but more
expensive amitation.
Another limitation is the inability of the
circuit to provide a pure sine wave output wave form. This is because it
is quite expensive to design a pure sine wave inverter circuit.
1.5 ORGANIZATION OF THE PROJECT
The
5KVA, 220 – 240v, 50Hz inverter is constructed using the following
components: Resistor capacitors, semiconductor diode, transistors,
(MOSFET), integrated circuit (ICS), transformer. The MOSFET is the major
component used in the inversion of Direct Current (DC) to Alternating
current (A.C)
This 5KVA inverter project report is arranged in the following sequence.
-
Chapter one discusses a general introduction to the project. It gives
us a background of the project Helping us to see the relevance of this
inverter project in the world today, it also discusses the objectives of
an inverter as well as type.

ABSRACT - [ Total Page(s): 1 ]This project review the conformability of uninterrupted power supply through the use of power inverter, However, inverter is of different categories base on power rating such as 1KVA, 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 oil, fuel and maintenance of plant is over. ... Continue reading---
