Re: Changing the mutual inductance coefficient of K statements with time


 

I have a feeling you should explicit the leakage inductances (i.e.
making them visible components in the schemo) and apply the statement to
them.

Hello,

I am an electronics engineer and I work on wireless power supplies.
For one of my simulations, I want to couple two inductors and I would
like to simulate the design for various values of K.

Could someone please let me know why I can not use the following
syntax as an LTSPICE directive?

K L1 L2 V(Var)

Where Var is a voltage source I have specified in the simulation
circuit and it is a PWL (ramp function).

This syntax works for a variable resistor. I am wondering whether it
is actually possible to apply the same logic to a coupling coefficient
of the K statement.

Please help !!

Thank you.

Falcon
