Error for current/voltage in 3 inductances circuit

Hi,

 

I'm trying to test a circuit with 3 inductances L1, L2 and L3, links like this:

 

L1 <-> L2 with 0.9 coef

L2 <-> L3 with 0.9 coef

 

I add my Multisim file for test it.

But the current and voltage increase very quickly !

 

First I try to understand why voltage and current increase very quickly, I think this come from the flux.

Here some details of signal :

Second, if I'm looking at energy input/output, it's not possible, more output than input. So maybe it'sa problem from the software, or my circuit has not good parameters.

 

I hope you can help me to find my error :smileyhappy:

hello,

What inductance did you take?

Which model did you use?

Hi,

 

The model is in zip file. I understood it's because Multisim don't verify reality of K between 3 or more inductances. K3 must be like K1*K2 not lower.
