Fesial energy storage inductor

Why is fesial a good insulator?

The soft magnetic performance is superior to that of other FeSiAl cores that have been mechanically crushed. Furthermore, the ability to tune the insulating layer also highlights an effective strategy for optimizing the soft magnetic properties of FeSiAl cores.

How to optimize soft magnetic performance of fesial cores?

Cheng, H., Zhang, L., Liu, X. et al. Optimizing Soft Magnetic Performance of FeSiAl Cores by Tailoring the Al 2 O 3 /SiO 2 Insulating Layer in Ethanol/Aqueous Mixed Solvents. J. Electron.

What is fesial based soft magnetic composite (SMC)?

FeSiAl-based soft magnetic composites (SMCs), prepared from insulated FeSiAl powders, are widely applied in electronic devices. However, it is still challenging to achieve high magnetic and mechanical properties simultaneously due to the undesirable insulation layer. Here, double Al 2 O 3 insulation layers are prepared for FeSiAl SMC.

How can fesicr soft magnetic composites improve thermal conductivity?

FeSiCr soft magnetic composites (SMCs) based on powder coated with an Al 2 O 3 /resin insulation layer by the sol-gel method were fabricated. Al 2 O 3 /resin insulation treatment not only effectively optimized the core loss, resistivity, and quality factor Q of SMCs, but it also improved their thermal conductivity.

How to fabricate fesial SMC?

Here, we succeed in fabricating FeSiAl SMC by confined solid-state reaction between TiO 2 and FeSiAl matrix, which leads to the formation of homogeneous and lattice-matched Al 2 O 3 layer and brings about effective electrical insulation of FeSiAl particles.

Is fesial a good energy saving device?

Meanwhile fast domain wall displacement and small hysteresis loss are directly observed by in-situ Lorenz TEM. The obtained FeSiAl SMC exhibits low power loss of 130 mW·cm −3 (50 mT, 100 kHz) and high effective permeability of 143, which shows great application potential in energy-saving and high-efficiency devices.
