Alpha-Core Intros New Amorphous Magnetic C-Cores
Amorphous magnetic C-cores.
Shelton, CT — Alpha-Core, a division of Bridgeport Magnetics Group Inc., is introducing a new line of Magnetic Amorphous C-Cores. With superior magnetic properties, Amorphous Cores offer several advantages over cores made of Silicon Steel, Ferrite and Powdered Iron, such as almost 50 percent size and weight reduction due to its much higher saturation induction. Its ultra-thin lamination thickness of one mil (25µm) results in much lower core losses.
Amorphous Cores can operate at higher frequencies at the same flux level while conventional steel cores as the frequency increases must operate at lower flux densities and to compensate the designer must use larger size cores. Another advantage is a wide operating temperature range from -55 to +130°C.
The properties of Amorphous C-cores make them highly suitable for transformers in switching mode power supplies, operating at frequencies from 400Hz to 20kHz and inverters in welding equipment, wind turbines and solar panels. Other uses that benefit from amorphous cores include output filter chokes in large SMPS, power factor correction chokes in UPS systems and high power lamp ballasts. The amorphous magnetic alloy is made in a process in which molten metal is cast into thin ribbons.
