Coil enhancements for high efficiency wireless power transfer applications
Sampath, J.P.K., Alphones, A., Vilathgamuwa, D. Mahinda, Ong, Andrew, & Nguyen, X.B. (2014) Coil enhancements for high efficiency wireless power transfer applications. In Proceedings of the 40th Annual Conference of IEEE Industrial Electronics Society (IECON 2014), IEEE, Sheraton Hotel Dallas, Dallas, Texas, USA, pp. 2978-2983.
Achieving high efficiency with improved power transfer range and misalignment tolerance is the major design challenge in realizing Wireless Power Transfer (WPT) systems for industrial applications. Resonant coils must be carefully designed to achieve highest possible system performance by fully utilizing the available space. High quality factor and enhanced electromagnetic coupling are key indices which determine the system performance. In this paper, design parameter extraction and quality factor optimization of multi layered helical coils are presented using finite element analysis (FEA) simulations. In addition, a novel Toroidal Shaped Spiral (TSS) coil is proposed to increase power transfer range and misalignment tolerance. The proposed shapes and recommendations can be used to design high efficiency WPT resonator in a limited space.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
