Incorporating field non-uniformity and anhysteretic field calculation in the core loss characterization of ferrimagnetic materials
Abstract
Accurate core loss characterization of ferrimagnetic materials is important in the design of high-frequency power magnetic devices. In this thesis, two improvements to the process of core loss characterization of ferrimagnetic materials are made. First, the characterization is made based on the anhysteretic rather than hysteretic (actual) flux density. This makes design predictions of losses more accurate, as such predictions are based on the anhysteretic fields. Second, the effects of test sample flux density nonuniformity on the characterization process are accounted for.
