Buck converter reactor NTT AMCC 400
REO TSS reactor with amorphous core
Description
As a passive inductive component in power supplies and in power electronics, the buck-converter reactor is used for attenuating undesirable frequencies or for saving and storing energy.
The term buck-converter reactor indicates the complete ready-for-use unit containing the reactor, air cooling, mounting and connections. The reactors are available with different cores, which enables individual selection depending on the requirement of the application. In addition to iron-based cores, chokes with cores of amorphous alloy are becoming more common, in the form of toroidal cores, cut strip-wound cores or special custom solutions.
The use of amorphous materials offers an exceptional combination of high saturation flux density (1.56 T) and a high permeability. In addition to the high temperature class, further features of amorphous alloy include low hysteresis and eddy-current losses, suitability for the medium-frequency range (<20 kHz) and use for high powers up to 500 kVA.
Advantages
