FOREWORD

It is my great pleasure to present this laboratory manual for third year ELECTRICAL ELECTRONIC & POWER engineering students for the subject of Power Electronics. Keeping in view the vast coverage required for visualization of concepts of power electronic circuit simulations. As a student, many of you may be wondering with some of the questions in

your mind regarding the subject and exactly what has been tried is to answer

through this manual.

Faculty members are also advised that covering these aspects in initial stage itself, will greatly relive them in future as much of the load will be taken care by the enthusiasm energies of the students once they are conceptually clear.

LABORATORY MANUAL CONTENTS

This manual is intended for the third year students of ELECTRICAL

ELECTRONIC & POWER engineering branch in the subject of Microcontroller Applications. This manual typically contains practical/Lab Sessions related to Microprocessor 8085 and Microcontroller 8051 covering various aspects related to the subject to enhance understanding. Although, as per the syllabus, only descriptive treatment is prescribed, we have made the efforts to cover various aspects of microcontroller subject covering types of different aspects of 8051 Microcontroller Applications to make it meaningful, elaborative understandable concepts and conceptual visualization.

Students are advised to thoroughly go through this manual rather than only

topics mentioned in the syllabus as practical aspects are the key to

understanding and conceptual visualization of theoretical aspects covered in

the books.

Good Luck for your Enjoyable Laboratory Sessions
