In power powertrain, DC–DC converters, the selection of suitable magnetic core materials is a critical design consideration. It ensures weight and volume reduction and performance enhancement of such types of converters. 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. 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. 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. This study aims at providing a quick reference for designers to ease the selection of suitable magnetic core material for powertrain DC–DC converters.
