M.Printed circuit board coil design with reduced series resistance for high power inductive wireless power transmission systemsART-2022-132446Due to the growing use of the popular wireless power transmission (WPT) technology, an innovative method of coil design and optimization is presented in this paper. This method has been applied to develop spiral printed circuit board (PCB) coils with litz-wire structure. From the geometry definition, the design process is carried out by means of finite element analysis (FEA). In addition, as a complement to the design process, some prototypes of spiral PCB coils were built to contrast the simulation results and experimental measurements by means of the small-signal characterization, which reflects the success of the applied method.2022http://zaguan.unizar.es/record/12934910.1109/IECON49645.2022.9968891http://zaguan.unizar.es/record/129349oai:zaguan.unizar.es:129349info:eu-repo/grantAgreement/ES/MICINN-AEI/PDC2021-120898-I00info:eu-repo/grantAgreement/ES/MICINN/PID2019-103939RB-I00Annual conference of the IEEE Industrial Electronics Society 48th (2022), 22363114[6 pp.]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
