Amorphous cores offer several advantages over cores made of silicon steel, ferrite, and powdered iron. With a higher saturation induction, the cores are half the size and weight. The ultra-thin lamination thickness of one mil (25 um) results in significantly lower core losses. Amorphous cores can operate at higher frequencies at the same flux level ,while conventional steel cores must operate at lower flux densities as the frequency increases. The cores also have a wide operating temperature range from – 55 C to 130 C.
The amorphous magnetic alloy is made in a process in which molten metal is cast into thin ribbons.
The properties of amorphous C-cores make them suitable for transformers in switching mode power supplies operating from 400 Hz to 20 KHz and inverters in welding equipment, wind turbines, and solar panels. Other uses include output filter chokes, power factor correction chokes, and high power lamp ballasts.
