利用二维磁芯和折纸绕组将纳米晶共模电感的首谐振频率提升至10 MHz以上并改善性能

The first resonant frequency (fR) is usually believed to be mainly determined by material properties. Therefore, nanocrystalline common-mode inductors are typically used at frequencies below several tens of kilohertz. This letter proposes an inductor with a 2-D core and origami winding to increase the first fR without changing the material. Especially, for nanocrystalline, the proposed 2-D structu...
