    Guillaume Vigneau received a Master degree in electronics and radiocommunications from the french UPS University (Université Paul Sabatier) in 2012 and is currently doing his Ph.D. studies in wireless power transfer. His main research interests are on the improvement of wireless power transfer for low power devices, antenna and circuit design, applied in automotive environments.
    Mohamed Cheikh received a Master degree in electronics from ENSEEIHT engineering school in 2007 and received his Ph.D. degree in wireless communication in 2010. He now works on wireless car access and radiofrequency subjects in automotive environments.
    Rachid Benbouhout has Master degree in electronic engineering. After working on radiofrequency subjects as wireless car access, he is now the manager of the radiofrequency department at Continental Automotive France.
    Alexandru Takacs received his engineer diploma in Electronic Engineering from Military Technical Academy, Bucharest, Romania in 1999, Master (2000) and Ph. D. degree (2004) in Microwave and Optical Communications from National Polytechnic Institute of Toulouse, France. From 2004 to 2007 Dr. Takacs was Lecturer at Military Technical Academy of Bucharest and Associate Researcher at Microtechnology Institute of Bucharest. During 2011 he works as R & D RF engineer at Continental Automotive SAS France charged with antenna design and automotive electromagnetic simulation. Since 2012, Dr. Takacs is Associate Professor at University (Paul Sabatier) of Toulouse performing his Research within CNRS, LAAS Toulouse. His research interests include: design of microwave and RF circuits, energy harvesting and wireless power transfer, MEMS circuits and systems, small antenna design and optimization methods. He has authored or co-authored one book, 1 book chapter, and 15 papers in peer-review journals and over 70 communications in International Symposium Proceedings

  • This article presents a modeling and parametric investigation of printed circuit board (PCB) coils used in inductive power charging systems by using intensive full-wave electromagnetic simulations. Low frequencies applications (below 1 MHz) are targeted. The proposed modeling approach and design methodology are validated for wireless power transfer systems including transmitting (Tx) and receiving (Rx) coils. The impact of ferrite materials used for shielding and efficiency improvement is also analyzed. Optimized PCB coils allowing a theoretical efficiency of 88.7% at 100 kHz and 98.5% at 1 MHz confirms that PCB coils are appropriate for wireless power transfer at such frequencies.
