dc.description.abstract-translatedPurpose–The purpose of this paper is the presentation of an electrical equivalent circuit for inductivecomponents as well as the methodology for electrical parameter extraction by using a 3 Dfinite elementanalysis (FEA) tool.Design/methodology/approach–A parameter extraction based on energies has been modified forthree dimensions. Some simplifications are needed in a real model to make the 3 Dfinite element method(FEM) analysis operative for design engineers. Material properties for the components are modified atthe pre-modeling step and a corrector factor is usedat the post-modeling step to achieve the desiredaccuracy.Findings–The current hardware computational limitations do not allow the 3 D FEA for every magneticcomponent, and due to the component asymmetries, the 2 D analysis are not precise enough. The applicationof the new methodology for three dimensions to several actual components has shown its usefulness andaccuracy. Details concerning model parameters extration are presented with simulation and measurementresults at different operation frequencies from 1 kHz to 1 GHz being the range of switching frequencies usedby power electronic converters based on Si, SiC or GaN semiconductors.Practical implications–This new model includes the high-frequency effects (skin effect, proximityeffect, interleaving and core gap) and other effects can be only analyzed in 3 D analysis for non-symmetriccomponents. The electrical parameters like resistance and inductance (self and mutual ones) are frequency-dependent; thus, the model represents the frequency behavior of windings in detail. These parametersdetermine the efficiency for the inductive component and operation capabilities for the power converters (as inthe voltage boost factor), which define their success on the market.Originality/value–The user can develop 3 Dfinite element method (FEM)-based analyses withgeometrical simplifications, reducing the CPU time and extracting electrical parameters. The corrector factorpresented in this paper allows obtaining the electrical parameters when 3D FE simulation would have developed without any geometry simplications. The contribution permits that the simulations do not need ahigh computational resource, and the simulation times are reduced drastically. Also, the reduced CPU timeneeded per simulation gives a potential tool to optimize the non-symmetric components with 3 D FEManalysis.en
