High-Frequency Soft-Switching PWM and Resonant DC/DC Converter Topologies for Solar/Fuel Cell Applications

Distinguished Lecture by Dr. Akshay K. Rathore (Senior Member, IEEE) from Department of Electrical and Computer Engineering, Concordia University, Montreal, Canada on the topic “High-Frequency Soft-Switching PWM and Resonant DC/DC Converter Topologies for Solar/Fuel Cell Applications”, scheduled on 16^th December 2017, at Krishna Hall, E-Block, Amrita School of Engineering, Bangalore starting at 10:00 hrs.

High-frequency operation is desired to realize a low cost, light weight and compact power electronics system. However, efficiency is major concern owing to hard-switching of the semiconductor devices at high device switching frequency. To mitigate the switching losses and achieve high efficiency, soft-switching is necessary. Soft-switching can be implemented in several ways, (1) Modulation technique, (2) Resonant tank leading to development of resonant converters, and (3) Auxiliary Transition Circuit. These types have their own merits and demerits based on the applications and specifications. Detailed analysis and results justify how to select and choose a type of soft-switching converter and topology for given source/load profiles and specifications.

Agenda

Biography:Dr. Akshay K. Rathore (Senior Member, IEEE) is an Associate Professor at Department of Electrical and Computer Engineering, Concordia University, Montreal, Canada since 2016. He received his Masters degree in Electrical Machines and Drives from Indian Institute of Technology, BHU, Varanasi, India in 2003 and was awarded Gold Medal for securing highest standing among all electrical engineering specializations. He received his PhD degree in Power Electronics from University of Victoria, BC, Canada in 2008. He was a recipient of NSERC Research Assistantship, University PhD full Fellowship, and Thouvenelle Graduate Scholarship. From Sept 2008- Oct. 2010, he had two subsequent postdoctoral appointments with University of Wuppertal, Germany, and University of Illinois at Chicago, USA.Presently, he invented a novel and innovative modulation technique to achieve snubberless zero current commutation and natural device voltage clamping of current-fed converters (single-phase and three-phase topologies) solving their traditional problem of turn-off voltage spike and opening its market for industries. Recently, he designed and developed other class Impulse Commutated Current-fed Converters (single-phase and three-phase) with soft-switching or semiconductor devices and solving classical turn-off device voltage overshoot problem.In addition, he contributed to development of synchronous optimal PWM (SOP) techniques for low switching frequency of medium voltage multilevel inverter topologies for high power industrial ac drives and common mode elimination. He has 1 patent, commercialized by WEG Brazil. At NUS Singapore, he was responsible for teaching and course revamp on Smart Grids, Modeling and Control of Advanced Power Converters, and Modeling and Control of Electric Drives. He has been listed in Marquis Who's Who in Science and Engineering in 2006, Who's Who in the World, and Who's Who in America in 2008. He was a consultant to WEG, Brazil, Crenergy Systems Pvt Ltd, Singapore and Robert Bosch (SEA) vt Ltd, Singapore. He has published over 130 research papers in reputed journals including 45 IEEE Transactions and IEEE international conferences, has 1 patent, and contributed to one book chapter.Dr. Rathore is Vice-Chair of IAS Industrial Automation and Control Committee (IACC), and Secretary of IAS Renewable and Sustainable Energy Conversion Systems Committee for 2016-17. He is an Associate Editor of IEEE Transactions on Industry Applications, IEEE Transactions on Industrial Electronics, IEEE Transactions on Transportation Electrification, IEEE Transactions on Sustainable Energy, IEEE Journal of Emerging Selected Topics in Power Electronics, and IET Power Electronics. He has edited 3 special issues on Transportation Electrification on various IEEE Journals.

Abstract:  “High-Frequency Soft-Switching PWM and Resonant DC/DC Converter Topologies for Solar/Fuel Cell Applications”

His Topic of discussion will mainly concentrate on the following points: High-frequency operation is desired to realize a low cost, light weight and compact power electronics system. However, efficiency is major concern owing to hard-switching of the semiconductor devices at high device switching frequency. To mitigate the switching losses and achieve high efficiency, soft-switching is necessary. Soft-switching can be implemented in several ways, (1) Modulation technique, (2) Resonant tank leading to development of resonant converters, and (3) Auxiliary Transition Circuit. These types have their own merits and demerits based on the applications and specifications. Detailed analysis and results justify how to select and choose a type of soft-switching converter and topology for given source/load profiles and specifications.

Thanks and with best regards.
