doi:10.1109/TIE.2018.2880721engSerrano, JavierLope, IgnacioAcero, JesúsNon-planar overlapped inductors applied to domestic induction heating appliancesART-2019-110858Domestic induction heating appliances are evolving from surfaces with three to five fixed cooking areas to flexible cooking zones. These are able to adapt to a number of vessels of any size and shape by using multiple coils. Some state-of-the-art induction systems make use of overlapped inductors in two layers, which combine the high efficiency of large inductors with the high flexibility of small adjacent coils. The main drawback of this concept is the unequal distance between different coils and the vessel, which implies that each coil presents a different impedance depending on its layer. This paper presents an induction system conformed by non-planar inductors. These inductors are designed in such a way that they can be assembled in overlapping structures while preserving equivalence among them, i.e. they all present the same impedance. The paper includes the FEM modeling of the non-planar coil, an analysis on the conductor''s losses and an experimental verification.2019http://zaguan.unizar.es/record/13094810.1109/TIE.2018.2880721http://zaguan.unizar.es/record/130948oai:zaguan.unizar.es:130948info:eu-repo/grantAgreement/ES/MINECO/PTQ-12-06713info:eu-repo/grantAgreement/ES/MINECO/RTC-2014-1847-6info:eu-repo/grantAgreement/ES/MINECO/TEC2016-78358-RIEEE Transactions on Industrial Electronics 66, 9 (2019), 6916 - 6924All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
