LTSPICE好像没有官方的询问渠道,真诚的希望在这里能够找到可执行的答案,谢谢!
想要仿真一个可饱和电感,类似与现实世界。(当通过电感的电流,或伏秒积超过一个值时,电感量会开始急剧下降,或者变为一个很小的电感值。)
想到的实现思路:
①是否有语句可以实现,用查表的方式,当电流在不同的区间,变为不同的电感量(5A>I>0A , L=100UH ; I>=5A , L=0.5UH)。之前在网上查到过可变电阻的仿真方式,如下。但是电感用同样的方法不能实现,仿真会报错。
②能够导入更为专业的磁芯模型,根据实际的B-H曲线,来实现饱和电感。

There appears to be no official inquiry channel dedicated to LTspice, and we sincerely anticipate finding practical and actionable solutions in this community. Thank you for your assistance.
I want to simulate a saturable inductor that is similar to the real world. (When the current through the inductor or the volt-second product exceeds a certain value, the inductance will start to drop sharply or become a very small inductance value.)
Proposed implementation ideas:
① Is there a statement to achieve this by using a lookup table, where the inductance changes to different values when the current is in different ranges? (5A>I>0A , L=100UH ; I>=5A , L=0.5UH)I previously found a simulation method for variable resistors online, as shown below.
However, this method cannot be applied to inductors, and the simulation will report an error.
② It is possible to import more professional magnetic core models and implement the saturable inductor based on actual B-H curves.
