Abstract: 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.

Key words: high permeability ferrite, dependence of the inductance on the frequency

摘要： 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。
