How to establish a nonlinear current source in simulink?

The circuit model I built in the simulink module contains a current source with a non-linear I-V relationship. How do I build this non-linear function? Is there any such module or reference case or solution? Thank you very much. How to establish a nonlinear current source in simulink?

Hi,

I understand that you want to establish a nonlinear current source in Simulink. For this, you can follow the below approach:

• Add a “voltage source” block to your Simulink model.
• Connect the “voltage source” block to the input of a “MATLAB function” block.
• Define the non-linear relationship you want to implement inside the “MATLAB function” block.
• Connect the output of the “MATLAB function” block to the input of a “current source” block in your model.

Hope this helps!
