FeSi soft magnetic composite, composed of FeSi magnetic powders with inter-particle coating, is the ideal magnetic core used in power inductor of smart meters due to its high saturation magnetization.
This study presents a novel soft magnetic composite powder that is suitable for the preparation of soft magnetic components working at high frequencies, such as inductors or reactors for power electronics.
Most importantly, the core-shell structure and self-conductive nanocrystal-FeSi usage as a robust mechanical skeleton can effectively avoid particle fracture, providing excellent cycling stability with 99.4% capacity retention over 500 cycles at 500 mA g −1 and 86% capacity retention over 1000 cycles at 1 A g −1, which is one of the best
FeSi based inductor core with a Co3O4 coating was prepared by ball milling combined with subsequent molding and annealing. Effects of the Co3O4 content on microstructure and magnetic properties of the FeSi/Co3O4 inductor core were systematically studied.

mposite inductor cores addressing the materials void in VHF and UHF frequency bands. In order to achieve the desired balance between high Bs and low core loss properties,
In this study, a new inductor material has been demonstrated, which utilizes the high magnetic saturation and thermally stable coating material in Somaloy 110i 5P in combination with low coersivity gas atomized FeSi.
The Fe-Si alloy anode and FSO1000 anode show especially poor cycling performance as their discharge capacities quickly decrease to <100 mA h g −1 after several cycles due to their fragile structure during the electrochemical process. In addition, the FSO also demonstrates a high rate performance.
These results clearly show a minimum in the core losses, for both high and low frequencies in both lubrication systems, with around 30-40 wt% FeSi added in the mixture, indicating that this addition renders the optimum composition for this material.
The Fe-Si alloy powders (73.3% Si, 21.4% Fe and other impurities) were obtained from a metallurgical factory. Firstly, the bulk Fe-Si alloy powders were crushed by ball milling (PM200, Retsch GmbH Inc., Germany) in order to obtain sub-micrometer Fe-Si alloy particles.
Compared to pure Fe-6.5% Si, the advantages of this new material arehigher magnetic saturation and high component density similar to that of pure Somaloy 110i 5P, as well as easy manufacturing procedures, i.e., the compaction pressure is low or moderate (800-1200 MPa vs. 1200-2000 MPa for pure FeSi) which reduces production costs.
