Power Electronics - Past, Present & Future
Speaker: Professor Ajit K Chattopadhyay, Fellow, IEEE
When: 2003-09-01 18:00:00
Venue: Room 119, B - block, Queensland University of Technology, Gardens Point Campus, Brisbane
Host: (seminar host unavailable)
Abstract:Power electronics (PE) has a long history and evolving development
since the beginning of electro-physics in the eighteenth century
with the concept of the 'semiconductor'. Its technology has gone
through an unanticipated rapid growth in the last forty years. This
presentation begins with a plausible definition and goal of power
electronics, emphasizing its key features and application areas to
develop a better understanding of the significance of this
development. It will then trace chronologically the significant
events / major breakthroughs in the history of power electronics
from its beginnings in 1783 until the development of the Silicon
Controlled Rectifiers in 1957, which has shaped the growth of PE as
it is today.
The second part of the presentation will consider the evolution of
modern power electronics as a complex multidisciplinary technology
synthesizing a number of diverse disciplines such as power switching
devices, new materials, microelectronics, converter topologies,
control, integration and packaging technologies, along with its
continuing application to all facets of power processing:
generation, transmission, distribution and utilization (
particularly in drive applications). From this comprehensive review
of the past and the present status of the developments in PE it will
be possible to assess the future trends and challenges presented by
this dynamic technology in the next few years of the 21st Century.
In the highly automated and economically competitive environment
worldwide power electronics (PE) will truly be the key to providing
a necessary interface between various energy sources and electric
loads in every field
Biography:Ajit K. Chattopadhyay (SM'83, F'91) received a in Electrical
Engineering from Calcutta University (B E College), India, the
M. Tech degree in Electrical Machines from the Indian Institute of
Technology (IIT), Kharagpur and his PhD degree from the University
of Manchester (UMIST) England, in 1958, 1963 and 1971 respectively.
He has authored/co-authored over 118 publications (including 40 in
IEEE Transactions/ Conference Records) in the field of Electrical
Machines, Power Electronics and Microprocessor-based control of DC
and AC drives. He has filed 4 patent applications. He has authored
two complete video courses on Machine Drives with Power Electronics,
sponsored by the Center Light refreshments will be provided at the
conclusion of the seminar during which time the speaker will be
available for more informal questions and discussions. of
Educational Technology, IIT Kharagpur and written a Chapter on AC-AC
Converters in Power Electronics Handbook published by Academic Press
(USA), in 2001.
For his outstanding contributions in Power Electronics, Dr
Chattopadhyay received the Bimal Bose Award in 1986 from the
Institution of Electronics and Telecommunication Engineers (IETE),
India. He was elected IEEE Fellow in 1991 for 'leadership in the
development of Power Electronics research and educational programs
in India'. He is a Fellow of the Indian National Academy of
Engineering, a Life Fellow of the Institution of Engineers (IE) (I)
and the IETE (I). He was awarded the Bharatia Cutler Hammer Prize in
1986, the Tata Rao Prize (1993-1994) and a Certificate of Merit
(1992) from IE (I) for his papers. He has served on the Editorial
Boards of the Journals of the IETE (I) and the Electrosoft (UK). He
has served on the program committees of many international
conferences and chaired many technical sessions in India and abroad.
Since his retirement from IIT, Kharagpur, Dr Chattopadhyay has
worked in the Electrical Engineering Department, Bengal Engineering
College (Deemed University), Howrah as an AICTE Emeritus Fellow from
July 1996 to March1999 and as a CSIR Emeritus Scientist from April
1999 to February 2001. He is now working as a UGC Emeritus Fellow
at the same place since 1 January, 2002. He has served as the
IEEE-IAS Calcutta Chair since its establishment in November, 1997
and he has been elected as a Distinguished Lecturer of IEEE Industry
Applications Society for two years, 2002-2003
Type: IEEE Power Engineering Chapter / IEEE Industrial Applications Society seminar
