How to set the circuit to simulate an inductance

Hello,

I have a model of an UI inductance and I dont know how to set up the circuit to put all the current harmonics the inductor will suffer.The first thing I thought is to put different current sources and change the frequency of the current sources, putting them in parallel and connected with the two series coil. I am not able to follow my idea because I dont know how I can change the frequency of each current source. Furthermore, I would like to put DC current source as one of the harmonic. What would you do?

I would put the model attached if you want to take look.

Thank you,

Iñigo Izaguirre

Thank you for your help. How would you do the simulation in transient application?

In Transient application, there is two ways to do it:

You can create for each harmonic a current source and you put all the current source in parallel. Each harmonic is defined by a formal (for example harmonic N)1, I_1(t)=i_1*sqrt(2)*sin(2*pi()*f_1*t), I_5(t)=i_5*sqrt(2)*sin(2*pi()*f_5*t)) you do the same thing for all harmonics
You can use one current source and in the current source you define the current using I/O parameter
- I_T= I_1(t)+ I_5(t)+ I_7(t) I_11(t)+….

For the frequency you can use also I/O parameter for each value

Thanks.

Hi,

I checked your project and the application used is steady state. In your case you can use a multi-frequency by creating an I/O parameter (you can change this parameter during the solving scenario) but for one current source. You can’t not several current source with different values of the frequency.

The second way is to create a separate project for each frequency.

If you use a transient application, in this case you cand do the multi frequency in the same project.

Thanks.
