Toroidal magnetic cores are made of a Fe-based thin (20 microns) nanocrystalline ribbon and have low loss, high induction of saturation, high operating temperature (up to 150 C), high magnetic permeability. Magnetic cores have a negative temperature coefficient of losses that provides stabilization mode transformer temperature.
Application in power high- frequency transformers push-pull,bicyclic SMPS, DC-DC converters, audiotransformers.
High permeability provides good electromagnetic connection of windings and low leakage inductance values.
