Design/methodology/approach: An electromagnetic description of the inductor system is performed to substitute the effects of the induction load, for a mathematical condition, the so-called impedance boundary condition (IBC). Findings: A significant reduction in the computational cost of electromagnetic simulation has been achieved through the use of the IBC, resulting in a computation time approximately 400 times faster than time domain simulation. Moreover, an alternative method has been developed to experimentally identify the parameters that determine the magnetic behavior of the induction load. Finally, further research has been conducted to understand the relationship between the equivalent impedance of an induction load and the excitation current level. Practical implications: This work is performed to achieve a better understanding of the fundamentals involved in the electromagnetic modeling of an induction heating system. Originality/value: This paper introduces the dependence on the excitation level based on a first harmonic approximation and extends the IBC to nonlinear magnetic materials which allows the identification of the magnetic characteristics of the induction load. info:eu-repo/grantAgreement/EUR/AEI/CPP2021-008938 info:eu-repo/grantAgreement/ES/MICIU/PID2022-136621OB-I00 info:eu-repo/semantics/openAccess by-nc https://creativecommons.org/licenses/by-nc/4.0/deed.es 1.0 2024 MATHEMATICS, APPLIED 192 / 344 = 0.558 2024 Q3 T2 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS 151 / 177 = 0.853 2024 Q4 T3 ENGINEERING, ELECTRICAL & ELECTRONIC 304 / 368 = 0.826 2024 Q4 T3 0.324 2024 Applied Mathematics 2024 Q3 Electrical and Electronic Engineering 2024 Q3 Computer Science Applications 2024 Q3 Computational Theory and Mathematics 2024 Q3 2.2 2024 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Ortega, José Carretero, Claudio Universidad de Zaragoza (orcid)0000-0001-7901-9174 Martínez, Juan Pablo Universidad de Zaragoza (orcid)0000-0001-9221-9306 Acero, Jesús Universidad de Zaragoza (orcid)0000-0001-7207-5536 2002 385 Universidad de Zaragoza Dpto.
