Thesis Abstract

Abstract
Inverters play a crucial role in converting direct current (DC) into alternating current (AC) for various applications, such as powering electronic devices and solar energy systems. This research project focuses on the design and construction of an inverter that can efficiently and reliably convert DC power to AC power. The inverter design incorporates key components such as transistors, capacitors, and diodes to facilitate the conversion process. The project involves detailed research into the principles of inverter operation, including pulse width modulation (PWM) techniques to control the output waveform and voltage regulation mechanisms. By optimizing the design parameters and component selection, the inverter aims to achieve high efficiency and performance in converting DC to AC power. The construction phase of the project involves the assembly of the designed circuit on a printed circuit board (PCB) using appropriate soldering techniques. Careful attention is given to the layout of components to minimize interference and ensure proper functioning of the inverter. Testing procedures are implemented to verify the functionality and efficiency of the constructed inverter. Additionally, the project explores the potential for expanding the inverter design to accommodate higher power ratings and support a broader range of applications. By evaluating the scalability of the design, the research aims to provide insights into adapting the inverter for commercial and industrial use. Overall, this research project contributes to the understanding of inverter technology and provides practical insights into the design and construction processes. The developed inverter prototype serves as a valuable platform for experimentation and further optimization in the field of power electronics. The project findings offer valuable implications for enhancing the efficiency and reliability of DC to AC power conversion systems, with potential applications in renewable energy systems, backup power supplies, and electronic devices.

Thesis Overview

INTRODUCTION

BACKGROUND OF THE STUDY

All modern engineering system includes certain aspects of control system at some point in their broadcast scenes, control engineering and the associated theory are concerned with the means of making system to behave in a desired may. The system on this thesis is a DC " AC inverter which is an apparatus used in the conversion of direct current (DC) to alternating current (AC). In our contry today, this equipment is not all that in use not because it is not important but because people never give it a thought as per the construction and design. It is meant for use with a 12volts leadacid battery of it’s in a car for example a suitable output voltage of 240volts AC obtainable.

This output voltage of 240volts AC can be used for powering small electrical appliances such as lights, electrical tools radio, soldering iron, fan etc. However, it is with mentioning that the DC generated with this appliance is nothing comparable to the AC generated by big generation duration. This appliance is therefore suitable for short time replacement for the real AC generation especially in the remote areas and it is install where electrical appliances are sold and the need might arise for it to be tested and certified good. Another main area where this equipment can be of great utility is in communication system. In a situation where there is a constant AC power supply failure example in offices DC " AC inverter is needed and such cases, inverter can be used as a source of light.

Most industries in the country do not make use of DC " AC inverter because the are through to be costly with respect to the task they perform. However, putting into consideration the task, this appliance can perform. It can be concluded that it is cheaper. The construction is simple, cheaper, easy to operate and portable. The usefulness of this device and the function cannot be over emphasized especially now that our country is passage through a very sensitive era in our power generating Authority (NEPA) has been dubbed NEVER EXPECT POWER ALWAYS. In these times when control and monitor of complex field operations have based in computer, a failure of AC, power supply to communication equipment means work stoppage and to some small scale industries a lot of economic and materials losses is avoidable.
