Advances in Wireless Power Transfer (WPT) Technology
Abstract: Wireless Power Transfer (WPT) systems, based on inductive power transfer (IPT) technology, are becoming increasing popular in many applications. As research in this area is progressing at a rapid rate, this seminar introduces some of the recent advances in IPT based WPT technology. The seminar discusses new circuit and magnetic modelling techniques that can be employed to investigate different types of compensation circuits and coil structures of WPT systems. This is followed by an introduction to the bi-directional wireless power transfer (BD-WPT) technology, which has been developed for V2X applications, and presentation of its latest advances. This includes the optimal control strategies, based on impedance matching, that allow for regulation of power transfer in both direction at maximum efficiency, regardless of large variations in coupling and load. .
Bio: Udaya K. Madawala graduated with
a B.Sc. (Electrical Engineering) (Hons) degree from The University of Moratuwa,
Sri Lanka in 1987, and received his PhD (Power Electronics) from The University
of Auckland, New Zealand in 1993 as a Commonwealth Doctoral Scholar. At the
completion of his PhD, he was employed by Fisher & Paykel Ltd, New Zealand, as a
Research and Development Engineer to develop new technologies for motor drives.
In 1997 he joined the Department of Electrical and Computer Engineering at The
University of Auckland and, at present as a Full Professor, he focuses on a
number of power electronics projects related to planning of EV charging
infrastructure, and bi-directional wireless EV charging systems for V2X
