中文摘要
纳米晶磁芯因高饱和磁通密度和轻量化优势在无线电能传输(IPT)中应用广泛,但其高导电性带来的涡流损耗限制了高频应用。本文提出了一种集成电感-电容纳米晶磁芯的新概念,旨在优化磁性元件设计,提升高频下的功率密度与效率。
English Abstract
Nanocrystalline magnetic cores have been increasingly adopted in inductive power transfer (IPT) systems, due to their high saturation flux density, lightweight, and design flexibility. However, the high conductivity of nanocrystalline materials leads to increased eddy current losses, which has been a drawback in high-frequency applications. This letter proposes a novel concept of the integrated in...
