An Introduction to Wireless Power Transfer: Past, Present and Future Directions
Grant Covic, University of Auckland
Jürgen Meins, Technical University in Braunschweig
This tutorial will provide useful background information to those new to the field of Wireless Power Transfer. The overview will include:
- Background of inductive systems, understanding of why resonance and options for tuning, common magnetic topologies for stationary and compatibility with dynamic charging
- Aspects of both stationary and roadway multiphase systems with examples of commercial developments
University of Auckland
Grant A. Covic (Senior Member IEEE) received his BE (Hons), and PhD degrees in Electrical and Electronic Engineering from The University of Auckland (UoA), New Zealand in 1986 and 1993 respectively. He was appointed as a full time Lecturer in 1992, a Senior lecturer in 2000, an Associate Professor in 2007 and to Professor in 2013 within the Electrical and Computer Engineering Department at the UoA, New Zealand.
In 2010 he co-founded (with Prof. John Boys) a new global start-up company “HaloIPT” focusing on electric vehicle (EV) wireless charging infrastructure, which was sold in late 2011.
Presently he heads power electronics research at the UoA and co-leads the interoperability sub-team within the SAE J2954 wireless charging standard for EVs.
Today his research and consulting interests include power electronics, electric vehicle battery charging and inductive (contact-less) power transfer (IPT) from which he has published more than 100 refereed papers in international journals and conferences.
He also holds a number of US patents with many more pending, from which licenses in specialized application areas of IPT have been granted around the world.
Technical University of Braunschweig
Since 1994 Dr. Meins has been a Professor at the Institut for Electrical Machines, Traction and Drives (IMAB) at the Technical University of Braunschweig.
His professional focus over the years has included Development of maglev technologies, new rotating machines, electromechanical systems as well as Contactless Power Supply Technologies for Transport and Traffic Systems, Transrapid Maglev Systems and Urban Transport Systems.
He holds patents in the field of Maglev Technologies, Electrical Machines, and Contactless Power Transfer.
Dr. Meins earned both his BS and PhD in Electrical Engineering from the University of Braunschweig.
