Project Abstract

Abstract
This project focuses on the design and construction of a 2KVA power inverter. Power inverters are essential devices that convert direct current (DC) power from a battery or solar panels into alternating current (AC) power that can be used to run various household and industrial appliances. The growing demand for reliable and efficient power sources has led to increased interest in developing power inverters with higher power capacity. The project aims to design a 2KVA power inverter that can efficiently convert DC power to AC power for powering small household appliances or serving as a backup power source. The inverter's design involves selecting suitable electronic components such as MOSFETs, capacitors, transformers, and control circuitry to achieve the desired power output. The inverter will also include protection circuits to safeguard the device and connected appliances from overloads, short circuits, and other electrical faults. The construction phase of the project involves assembling the selected components on a printed circuit board (PCB) according to the design specifications. Careful attention will be paid to the layout and wiring of the components to ensure proper functionality and efficiency. The construction process will also involve testing the inverter under various load conditions to evaluate its performance and efficiency. The completed 2KVA power inverter will undergo rigorous testing to assess its reliability, efficiency, and overall performance. The inverter will be tested for its ability to provide stable AC power output at the rated capacity and under varying load conditions. Efficiency tests will be conducted to evaluate the inverter's energy conversion efficiency and its performance in converting DC power to AC power. Overall, this project aims to design and construct a 2KVA power inverter that can serve as a reliable and efficient power source for small-scale applications. The successful completion of this project will contribute to the advancement of power inverter technology and provide a practical solution for addressing power supply challenges in various settings.

Project Overview

INTRODUCTION

BACKGROUND OF THE PROJECT

Electrical/Electronic Engineering is a very important element that cannot be neglected in the society as it is deeply sewn into the fabric of the society. It is an important element in homes to power household devices like electric bulbs, electric cooker, refrigerator, television set, etc. It also finds applications in various work places/offices to power devices like light bulbs, air conditioners, computers, etc. In fact electronic/electrical engineering is the foundation of careers of many people doing both white-collar and blue-collar jobs.

Despite the development, the power generation and distribution across the country is abysmally low and is very far from being enough. This is a problem that has provoked so many alternative power solutions to cater for the increasing power needs.

The popular solution is the generator set. There are sets of different sizes and ratings; they also use fuel like petrol or diesel. However the generating set has disadvantages like noise pollution, air pollution (it has led to the death of many people in Nigeria), and an expensive alternative power solution.

That is why an alternative, the power inverter is advocated for homes since the load is small compared to industrial setups. It must be noted however that a generating set is still advisable for an industrial setup despite its disadvantages. The power inverter solves most of the disadvantages of the generating set regarding cost of fuel, noise pollution, and air pollution.

The power inverter is an able alternative power supply source for homes with bad electricity supply from electricity utility companies.

PROBLEM STATEMENT

Faced with the problem of abysmal power supply from supply authorities, noise pollution, air pollution, cost of the popular alternative: generator sets, there is a need for a less noisy, pollution free and cheap solution to power problems in the houses of individuals and families in Nigeria.

AIM AND OBJECTIVES

AIM

The aim of this project is to design and construct a 2kVA power inverter with an inbuilt charging system that will be charged when there is supply from mains and supply the inverter when there is no supply from the mains.

OBJECTIVES

1. To design and construct an inverter that will be able to power essential loads in a house.
2. To design and construct an automatic switching circuit for changing power between the battery and the mains power supply.
3. To design and construct an electromechanical switch for altering power supply and cutting battery supply when it is low.
4. To design and construct an alarm circuit that beeps when the load on the iverter is beyond the inverter capacity.

SCOPE OF THE STUDY

The scope of this study is based on the design and construction of a 2kVA power inverter and its process of operation.

 SIGNIFICANCE OF THE STUDY

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 loads in the absence of supply from power supply utilities in the country.
