REO TSS reactor with amorphous core
Description
The buck converter reactor as an inductive passive component in the power supply and in power electronics is used to attenuate unwanted frequencies or for saving energy and storage.
The term buck-converter reactor indicates the complete ready-for-use unit containing the choke, 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, reactors 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 a special combination of high saturation induction (1.56 T) and high permeability. Low remagnetization losses as well as the possibility of use in the medium frequency range (< 20 kHz) and at high powers of up to 500 kVA are additional features of amorphous alloys, alongside their high thermal class.
Advantages
