REO TSS reactor with iron core
Description
The buck converter chokes 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 choke refers to the complete, ready-to-use unit consisting of a choke, cooling air duct, suspension, and connections. The chokes can be equipped with various cores, thus enabling individual use depending on the requirements. In addition to the iron-based core material, the amorphous alloy is now increasingly used as the core, which is processed into toroidal cores, cut cores, or special customized 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

- Can be used in the kHz region
- Equal or higher power ranges with smaller components
- significantly lower weight
- High flux densities
- Usable up to temperature class H (180°C)
- Protection class IP 65
