Improved permeability of Fe based amorphous magnetic powder cores by adding Permalloy

Journal of Magnetism and Magnetic Materials, 2017
Abstract This paper focuses on improving the permeability of Fe-Si-B based amorphous magnetic powder cores by addition of micron-sized ferromagnetic crystalline metal particles (Permalloy). The effects of Permalloy content, size and the amount of insulation on magnetic properties and density were investigated.

Novel Fe-based amorphous and nanocrystalline powder cores for high-frequency power conversion

Journal of Magnetism and Magnetic Materials, 2020
Abstract The present work demonstrates the high-frequency core loss performance of Fe-based amorphous and nanocrystalline powder cores, initially produced by gas atomised powder, consolidated using sieved particles ≤20 µm, and isolated by a precise insulating layer of polymer to limit the inter- and intra-particle eddy currents to attain enhanced ...

Novel Fe-based amorphous compound powder cores with enhanced DC bias performance by adding FeCo alloy powder

Journal of Magnetism and Magnetic Materials, 2020
Abstract Novel amorphous magnetic-compound powder cores (AMPCs) composed of a mixture of water-atomized FeSiBPNbCr amorphous powder and FeCo alloy powder were successfully fabricated through cold pressing. FeCo alloy powder, which exhibits a high magnetic flux density (Bs) of 2.35 T, can improve the Bs and DC bias performance of the AMPCs.

Low core loss combined with high permeability for Fe-based amorphous powder cores produced by gas atomization powders

Journal of Alloys and Compounds, 2018
Abstract Toroid-shaped Fe-based soft magnetic amorphous powder cores were prepared from Fe76Si9B10P5 (at.%) amorphous powder by gas atomization and subsequent cold pressing with epoxy resin as a binder and insulation. The influence of epoxy resin content and annealing temperature on the magnetic properties of the amorphous soft magnetic powder cores ...
