In the news I read that it's now possible to use n mutual inductors with the spice converter. Which netlist do I need? I tried something like:
.SUBCKT ind4 1 2 3 4
MUTX:K12K13K14K23K24K34 1 _ref 2 _ref 3 _ref 4 _ref L1=1.3uH L2=1.3uH L3=1.3uH L4=1.3uH k12=0.1 k13=0.019 k14=0.013 k23=0.1 k24=0.019 k34=0.1
but I am not very familiar with spice netlists.
The qucsconv program is able to translate something like this:
* mutual inductances
L1 1 2 1n
L2 3 4 1n
L3 5 6 1n
L4 7 8 1n
K12 L1 L2 0.1
K13 L1 L3 0.2
K14 L1 L4 0.3
K23 L2 L3 0.4
K24 L2 L4 0.5
K34 L3 L4 0.6
But also for an arbitrary number of inductors and coupling coefficients.
Does this solution use the MUTX compponent?
If you pipe it through the qucsconv (SPICE to Qucs converter), then: yes.
$ qucsconv -if spice -of qucs < infile > outfile
You will see in the result the MUTX component of Qucs.
I see, it does indeed use the mutx component, but if I compare the MUT2 and the MUTX (both with 3 inductors) it doesn't actually give the same results.
Unfortunately I can't place any screenshots on this forum so I will put it in the bug-reports.
I've just responded to your bug-report request. You made one apparent mistake while comparing them...
Ok, it's my fault!
Thank you very much for your quick response!
So now the results are identical? Can I close the bug again?
Yes, it's perfect now, I start liking the program more every day!
