The comparison of four magnetic materials namely Mega-Flux, JNEX-Core, amorphous, and ferrite cores for a buck–boost inductor for HEVs is provided in. The comparison of several magnetic core materials is provided in. The motivation of this paper is based on the aforementioned challenge and its main objective is to provide a comprehensive comparison of the magnetic materials for powertrain DC–DC converters and to provide a systematic approach for initial selection and ranking of magnetic core materials. All these conflicting requirements and the presence of numerous alternative magnetic core materials make the optimal choice of magnetic material intricate and a real design challenge. Moreover, magnetostriction, coercivity, market availability, the mechanical strength of the material, range of frequency of operation, volume, and cost are essential parameters needed to be considered. To meet these different requirements, designers are required to examine several parameters such as loss density, saturation flux density, and permeability characteristics as a function of temperature and frequency. Furthermore, they should have the good tensile strength to withstand harsh environmental conditions, vibrations, and shock in different environments. For such applications, the core materials are required to have lighter weight, smaller size, lower losses, low cost, high saturation flux density, wider operating temperature, better thermal stability, low acoustic noise, higher reliability, and sound stability across a range of loads at the operating frequency. Hence, the selection of its core material and its geometry are vital. The performance of powertrain DC–DC converters is mainly decided by the type and properties of the magnetic core material. Nanocrystalline (Finement FT-3M, HTX-002) JNEX-non oriented steel sheets of iron and siliconĢ6 kool mu E form, nanocrystalline (Finement) This study aims at providing a quick reference for designers to ease the selection of suitable magnetic core material for powertrain DC–DC converters. Based on the peculiar requirements of powertrain DC–DC converters, the most suitable magnetic core materials are identified and ranked with the help of the cobweb chart and the WPM. The weighted property method (WPM) is used to systematically select and rank the suitability of the magnetic core materials, and a multi-attribute decision-making analytical hierarchy processes is used to calculate the relative weight of different properties. This study provides a comprehensive comparison of magnetic core materials and a simplified cobweb chart that aids in the initial selection of magnetic core materials for powertrain DC–DC converters. It ensures weight and volume reduction and performance enhancement of such types of converters. In power powertrain, DC–DC converters, the selection of suitable magnetic core materials is a critical design consideration.
