摘要
This letter reports characterization of the novel nanocrystalline flake ribbon (NFR) soft magnetic material. 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.
