For this purpose, multi-stranded cables with litz structure are often used in induction heating applications. This paper presents an analysis and optimization of the efficiency of induction heating systems focusing on the optimal copper volume of the winding with respect to different constraints. The analysis is based on the concept of a one-strand one-turn coil, which captures the dissipative effects of an induction heating system and reduces the number of variables of the analysis. An expression for the efficiency of the induction heating system is derived. It is found that, with the geometry and the other parameters of the system fixed, efficiency depends on the copper volume of the windings. In order to use this result to optimize the efficiency of an application, volume restrictions, the packing factor and the window utilization factor are also considered. The optimum frequency for an induction heating system is also studied in this work. An experimental verification for both planar and solenoidal cases is also presented. 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-2014-TEC-08 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 7.151 2016 ENGINEERING, ELECTRICAL & ELECTRONIC 13 / 260 = 0.05 2016 Q1 T1 2.254 2016 Electrical and Electronic Engineering 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Acero, Jesús Universidad de Zaragoza (orcid)0000-0001-7207-5536 Carretero, Claudio Universidad de Zaragoza (orcid)0000-0001-7901-9174 2002 385 Universidad de Zaragoza Dpto.
