Acknowledgement
It would be great pleasure to write a few words, which would although not suffice as
acknowledgement of this long cherish effort, but in the absence of which, this report would
necessary be incomplete. So these words of acknowledgement come as a small gesture towards
all those people, without whom the successful completion of our project would not have been
possible.
With great respect and humble regards I would like to acknowledge the valuable guidance and
suggestion given to me by my major advisor Dr. R.R. Joshi Professor & Head, Department of
Electrical Engineering, College of Technology & Engineering. While doing simulation work and
preparing this report, Dr. R.R.Joshi showed their special interest and always favoured me by
giving his invaluable time and advice. His rich and varied experience as an academician
immensely helped me in understanding the project clearly.
I would like to express gratitude to Sh. Vinod Kumar, Assistant Professor, Department of
Electrical Engineering, College of Technology & Engineering, Udaipur for providing valuable
guidance . Without his kind co-operation and guide this task was tedious.
I also wish to express my gratitude to Sh. Jai Kumar Maherchandani, Associate Professor,
Department of Electrical Engineering, C.T.A.E, for his supervision and guidance.
I am privileged to express my deep sense of gratitude to Dr. B.P.Nandwana, Dean, College of
Technology & Engineering, Udaipur for his due attention and encouragement during the study
and also providing me the necessary facilities during the course of research.
I am gratified to record sincere thanks to the members of the advisory committee,
Words are insufficient to express my profound sense of gratitude to my guides, parents, and
friends whose encouragement gave me great physical and moral strength.
