高磁导率铁氧体及其变压器性质的频率依赖关系(英文)

Frequency Dependence of The Properties about High Permeability Ferrite and Transformer

研究了高起始磁导率（６０００～２００００）铁氧体和由该磁芯制成的变压器的电感频率依赖关系。当驱动频率由１００Ｈｚ增加到３００ｋＨｚ时，电感呈现Ｖ形Ｌ－ｆ曲线。详细讨论了形成Ｖ形曲线的原因。

The research of the high initial permeability( 6000 ～ 20000 )ferrite and the frequency dependence of inductance of the ferrite transformer made by high permeability ferrite core are presented.When the driving frequency increases from 100Hz to 300kHz the inductance shows a V shape L f curve.The reasons forming such a V shape curve are discussed in detail.
