Variable mutual inductance implementation

[RetoChristen]

Hi @Behnam
Yes, this is possible, as also mentioned in this forum post:

Can we simulate a coupled inductor with variable coupling coefficient or self inductances, varying with time?

The Variable Inductor component supports multiple phases and inductive coupling of the phases. Refer to the documentation of the Variable Inductor for a more detailed description on how this functionality is implemented. You will need to set the parameter “Inductive coupling” to “on”.

In your simulation it appears to be a rather fast change, so modeling it directly within the simulation is appropriate.

If the change were slow or simply a step, another option could be to stop the simulation at certain points and update the parameters before continuing.
