English Abstract

Mn-Zn ferrite is widely used as a core material in power electronic applications. However, core-loss modeling is challenging owing to the complexity of core-loss mechanisms and associated factors. The scarcity of experimental data is another significant impediment to the development of Mn-Zn ferrites. In this study, we propose a novel data-driven framework to construct an effective machine learnin...
