Alireza Khaligh, of the University of Maryland, will discuss “Advanced Power Electronics for Transportation Electrification” as part of the 2018/2019 Highlight Seminar Series.
Power electronics has emerged as an enabling technology in deployment of next generation of systems including transportation systems, energy harvesting applications, robotics, industrial systems, smart grids and data centers, among many others. The demand for higher efficiency, higher power density, specific power and better thermal management poses stringent challenges for these power electronic converters to accommodate. This presentation will put forward some of the current research areas, which are being pursued in the Maryland Power Electronics Laboratory (MPEL) with the emphasis on next generation onboard charging solutions for electric vehicles. The presentation will focus on developing highly efficient onboard chargers for plug-in electric vehicles. New techniques to enhance the efficiency of onboard chargers over the wide ranges of battery voltages will be discussed. It will also outline various configurations for integrated onboard chargers. It will introduce an innovative topology to combine an onboard charger and an auxiliary power module with the objective of enhancing the performance, while adding extra functionalities. This integration substantially increases the gravimetric and volumetric power densities, while enhancing the operation efficiency in light and medium loads. Furthermore, another onboard integrated charging strategy using the propulsion system of the vehicle will be outlined, which enables high-power fast charging with addition of a minimal onboard interface.
Alireza Khaligh is the Director of the Maryland Power Electronics Laboratory (MPEL) at the Department of Electrical and Computer Engineering (ECE) and the Institute for Systems Research (ISR) in the University of Maryland at College Park (UMD). He is also an Expert (Part time Program Manager) at the Energy, Power, Control and Networks (EPCN) Program at the U.S. National Science Foundation. His major research interests include modeling, design, and control of power electronic converters for transportation electrification, renewable energies, energy harvesting, and microrobotics. Khaligh is a recipient of various awards and recognitions including the 2018 Physical Sciences and the Overall Invention of the Year Award from UMD, the 2018-2017 Jimmy Lin Award for Innovation from ECE at UMD, 2017 Outstanding Young Alumnus Award from Illinois Institute of Technology, the 2016 E. Robert Kent Junior Faculty Teaching Award, the 2016 Junior Faculty Outstanding Research Award from Clark School of Engineering at UMD, 2015 Inaugural ISR Junior Faculty Fellowship from ISR at UMD, 2013 George Corcoran Memorial Award from ECE at UMD, 2010 Ralph R. Teetor Educational Award from Society of Automotive Engineers, and three Best IEEE Transaction paper awards. He is the Area Editor for of IEEE Transactions on Vehicular Technology, an Associate Editor of IEEE Transactions on Power Electronics, an Associate Editor of IEEE Journal of Emerging and Selected Topics in Power Electronics, and an Associate Editor of IEEE Transactions on Transportation Electrification. Khaligh is an author/co-author of over 180 Journal and conference technical papers, a Distinguished Lecturer of the IEEE Vehicular Technology Society (VTS) and also a Distinguished Lecturer of the IEEE Industry Applications Society (IAS).
The 2018/2019 Highlight Seminars Series will be held on Thursdays from 12:30 p.m. – 1:30 p.m. in Maeder Hall at the Andlinger Center. Lunch will be served at 12:00 noon in the auditorium lobby of Maeder Hall.
