1.4 SCOPE OF THE PROJECT
The scope of this project based on the design and construction of a 2KVA inverter and its operation, with the output power rating of 2KVA an maximum 7.27A and output voltage of 220V AC sources from a 12v inbuilt battery. This project is basically designed for single phase domestic loads.
1.5 METHODOLOGY
• To study of the previous work on the project so as to improve it efficiency
• Draw a block diagram
• Studying of various components of charge controller and inverter circuit
• Constructs an inverter circuit
1.6 MOTIVATION
With the obvious advantages of the inverter being a cheaper [in the long term] and cleaner source of energy, it is a device that can power essential leads. In the absence of supply from power supply utilities in the country. Inverter are the best when it comes to back-up since they can come up very fast and they generate little or no noise unlike generators. Even in an area with constant power supply, power outage due to natural cause and fault are usually unannounced. It therefore very important to prevent causality and loss of good will by having a reliable back-up power installed (OYETUNJITOBI,S. (2015), construction of 2KVA inverter Electrical/Electronic Engineering Project Power Option HND II Final Year Unpublished).
1.7 LIMITATION OF THE PROJECT
The major limitation of this project is that it cannot operate equipment or an electronic device that is above its rated current.
• Also the used of bulky transformer instead of copper transformer which is lighter and smaller in size but more expensive is another limitation.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTThis project presents the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices/homes in the absence of power supply from National Supply Authority.It is designed in such a way that it will take up to 12V DC from battery and inverts it to an output of 220V, 50Hz AC. It makes no noise during operation and not hazardous like carbon monoxide is generated to the surrounding. This is the feature makes it safe to used anywhere whe ... Continue reading---

It used the smartness of advanced control technology with the efficient conversion of electric power into the precise from required to control a function or process. In a industrial and commercial products, it is gaining ground mostly visible among inverters which converts direct current (DC) into a single or poly phase AC voltage at a desire aptitu ...

CHAPTER THREE - [ Total Page(s): 9 ]There are two main categories of transistor:1. Bipolar junction transistor (BJT): it also divided into NPN and PNP transistors.2. Field effect transistor (FET): it has three terminal unipolar solid state device in which current is controlled by an electric field as is done in vaccum tubes (http://www.amplifieredparts.com/2017/05/27 product/transistor.tip416-npn-epitaxial-transistors).There are two types of FETs.a. Junction field effect transistor (JFET)Metal-oxide semi- ... Continue reading---
