First, the limitations due to extrapolation of the fifth-degree polynomial functions used in the previous work are presented, resulting in inaccurate predictions in certain cases. As a solution, Bézier curves are proposed, which can accurately model the loss transition from low frequency (hysteresis loss) to high frequency (eddy loss), while remaining tangential outside of the parametrization range. The presented approach is not only more robust, but also requires less parameters to define the losses, while retaining similar or better accuracy than the approach. 979-8-3503-6444-6 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=178852 https://hdl.handle.net/20.500.11984/6827 Core loss Magnetic cores Ferrites Curve fitting Numerical analysis ODS 7 Energía asequible y no contaminante ODS 9 Industria, innovación e infraestructura ODS 13 Acción por el clima Alternative Approach Based on Bézier Curves to Model Core Losses With the Composite iGSE Method
