CHAPTER ONE

INTRODUCTION

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 country 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.

Answer of the day goes to Samuel Noah Ramrajkar, for answering the questoin,

"What is the reason for not using

diodes in parallel?"Answer: "It is because no diode can have the exact same characteristics. This makes on of the diodes conduct more. This gives more electron-hole pairs leading to even better conduction, and the process repeats till the point entire current flows thru one diode. In few cases it may destroy it. Thus the process of current hogging repeats on the next diode. Eventually all the diodes will blow out. Same is the condition for MOS,BJT,SCR not being connected in parallel."
