I'm still relatively new to comsol but have some exercises through. Now to my task. I want to simulate an inductive transformer.
N1= 21
N2=18
f=140kHz
R1 R2

V1 N001 0 SINE(0 330 140000)
R1 N002 N001 1
L1 N002 0 L ---canget to
R2 N003 0 1
L2 N003 0 L

.end
As example, i have oriented me during my model to the ecore transformer which can be found here on the website.
Now the model
Primary coil is a multi-turn coil domain modeled, secondary coil is also modeled as a multi-turn coil domain second
I have the netlist for LTspice imported and the inductivitäten replaced with I vr U.
Now to evaluate and the calculations
Study 1
cc calc
cc calc2
FD direct and full coupled
results
1. no current flows through R1
2. Z = 111 +79i Ohm is much too large, the R real must not exceed 3Ohm
I not looked at the values on the secondary side. Since the values on the primary side are not correct.
I also upload my model was easy someone can help me here.
perhaps someone can help me here.
Best regards Viktor
