Universidad de Zaragoza Analysis and design of tubular coils for wireless inductive power transfer systems 2017 Access copy available to the general public Unrestricted We evaluate copper tubes as alternative of litz wire for planar coils of inductive power transfer (IPT) systems. For this purpose, a design methodology focused on maximizing the product of the magnetic coupling and the quality factor is proposed. The methodology is based on a combination of FEA simulations and analytical calculations of the skin and proximity losses in the tube. Analytical calculations are based on solutions of Maxwell''s equations for a tubular geometry. These solutions are oriented to extract both skin and proximity losses in the tube. Performance of a prototype of 1.5 kW is evaluated and compared with a conventional litz-wire implementation. info:eu-repo/grantAgreement/ES/MINECO/CSD2009-00046 info:eu-repo/grantAgreement/ES/MINECO/RTC-2014-1847-6 info:eu-repo/grantAgreement/ES/MINECO/TEC2013-42937-R info:eu-repo/grantAgreement/ES/UZ/JIUZ-2015-TEC-12 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-6683-744X Serrano, J.
