This letter reports the characterization of a new nanocrystalline flake ribbon (NFR) soft magnetic material. Comparative analysis between ferrite N87, N27, and NFR was conducted at different temperature, frequency, and peak magnetic flux density. Experimental results demonstrated that the NFR exhibited lower loss density, higher magnetic flux density saturation, and better temperature stability in the range of 85 to 300 kHz. A LCL resonant tank-based circuit was employed for large signal characterization, and the mass-based stacking factor was used to describe the core structure of NFR. This letter suggests that NFR is a promising alternative to ferrite for high power magnetic cores due to its superior performance and flexible structures.

The comparative analysis among the ferrite N87, N27, and the NFR is presented at different temperature, frequency, and peak magnetic flux density, respectively. Experimental results prove that the NFR has lower loss density, higher magnetic flux density saturation, and better temperature stability from 85 to 300 kHz. A LCL resonant tank based circuit is employed for large signal characterization. The mass-based stacking factor of the NFR core is adopted to describe the core structure. This letter suggests that the NFR is a good alternative to the ferrite for high power magnetic cores due to its superior performance and flexibility structures.
