Alternative title: Effect of nanostructure on the core loss of soft magnetic materials

Description:

Soft magnets are important components in high-frequency power electronic devices, significantly contributing to efficient energy conversion. They are commonly utilized in transformers, inductors, and magnetic cores within high-frequency power converters. However, cutting-edge power electronics technologies demand soft magnets with minimal core loss at high frequencies. This study demonstrates that high-frequency core losses in Fe-based soft magnetic ribbons can be reduced through nanostructure engineering. We present the optimal microstructure designed to minimize core losses in the 10-20 kHz frequency range.
