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.

ABSTRACT This project review the conformability of uninterrupted power supply through the use of inverter. An inverter is a system that converts a direct current to an alternating current. However, inverter is of different categories base on power rating such as 1KVA, 1.5KVA,2KVA, 5KVA etc. Moreover, since the invention of inverter, some... Continue Reading
ABSTRACT This inverter is designed to convert ac power from higher capacity dc batteries to A.C voltage (power) for systems that use ac only. It uses 24v battery D.C times 2, which is converted by the MOSFET to A.C. it is used I.C. with the model number SG3525 where the four MOSFET is connected to it. It consists winding which enable to determine... Continue Reading

ABSTRACT This project is titled the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices and in homes in the absence of power supply from the national supply authority, NEPA. In order words the device / item serves as a substitute for NEPA which almost monopolises the power supply to... Continue Reading
ABSTRACT 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,... Continue Reading
ABSTRACT/CONCEPT It is a statement of fact that power plays a significant role in our daily life. However, Nigeria as a developing country has a lot of challenge in the area of electric power supply. The challenges include inadequate of electric power generating which causes instability of electric power supply in Nigeria. This problem is the... Continue Reading
CHAPTER ONE INTRODUCTION 1.1 THE BACKGROUND Welding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. It can simply be defined as the process of joining two or more pieces of metal to make the act as a single piece. This is often... Continue Reading
