Concurrent eddy current loss suppression and sustained permeability using trace amounts of highly insulating magnetic integranular inclusions

INV-18034 Background One approach to reduce eddy current loss is to restrict the flow of eddy currents by increasing the resistivity of the material. For this purpose, insulating oxide particles (e.g., CaO, SiO2, Nb2O5, Ta2O5, HfO2, ZrO2, and V2O5) have been shown to preferentially increase the grain boundary resistance of polycrystalline ferrite...
