摘要：

The loss density of the nanocrystalline material is experimentally characterized up to 500 kHz and above 1 Tesla in this paper. Flux density and loss density of the material under high operating temperature (150 degrees C) are calibrated and reported. The core preparing effect on magnetic loss density is also identified by experiments, which provides information necessary to practical magnetic designs. A new empirical core loss calculation method has been proposed and verified for the nanocrystalline material under resonant operations that are popular in high-frequency power converter applications.
