ABSTRACT
This project carried out is the construction of 2KVA inverter. It is an Electrical /Electronic device that is used to convert direct current (DC) to alternating current AC, which possible lead to power supply enhancement to the society.
This project was constructed to over come the failure of electricity in the society and also help in protecting electrical and electronic equipment that is used in the home or company. The converted AC can be at any required voltage and frequency with the use of appropriate transformer, switching, control circuit, multivibrators.
Inverters are commonly use to supply AC power from DC source, such as solar panels or batteries but in this construction battery was used. The arm of the construction of the inverter is that when there is power or failure interruption from the power generating Authority, the inverter will trigger from the dc to AC source where by giving steady electricity.
CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND OF THE PROJECT
It is a well know fact today that electrical power is not reliable. All over the world, there is significant electrical power supply interruption. Because of these electrical power interruption many electrical equipments have either developed problem or even stopped working entirely. Hence this has crippled many business thereby affecting even the economy of many countries as Nigeria. Also there is increase in occurrence of power disturbance, which can be viewed as a form pollution. High voltage spikes and momentary voltage drops are therefore common. These power disturbance may affect the performance of sensitive equipment in private and corporate organization causing critical loss of data and even damage to equipment.
In Nigeria today, it is not an over-statement to talk about the epileptic supply of electric power. This has become the order of the day such that many Nigerians now view these power outages as “Normal” and part of their daily life. A wide range of factors have been identified for this problem. They include natural disasters vandalism, maintainability sustainability inadequacies and lack of Local content. The problem of poor quality power supply can not be properly addressed without a review of other factors such as lack of political will to invest adequately in power sector, absence of replacement policy resulting in absolute equipment, unsustainable human capacity building and inadequate reward and remuneration system to motivate human resources term to perform well.
