Hi I am trying to use Nonlinear Transformer function. The web document indicates following parameters, which makes sense to me.
On the other hand, when open the model setting, the parameters are different from above. What am I missing. Thanks.

Hello Yoshi
From what I gather, you are working with Nonlinear Transformer and are trying to calculate the core magnetization characteristic.
The parameters listed in the MATLAB Documentation page linked below are describing the fundamental parameters used to calculate the core characteristics.
https://www.mathworks.com/help/sps/ug/nonlinear-transformer-characteristics.html
Some of these are parameters of the “Nonlinear Transformer” Simscape block. The Simulink example sets the values of these parameters with variables that have the same name as the ones listed in the linked example. Some other parameters listed in the example ‘Operational amplifier input resistance’, ‘Operational amplifier feedback resistance’, ‘Operational amplifier feedback capacitance’ etc. are parameters of separate blocks in the model used to calculate the characteristics.
Kindly refer to the linked documentation page of the ‘Nonlinear Transformer’ block to understand the parameters of the block:

I hope you find the above explanation and suggestions useful!

Hi Garmit, thank you for your response. I will try to include the opamp and other functions to run this as suggested. One more question if you dont mind is I tried to use the "Copy Command" to learn further though it returned following. Any idea what I am missing. Again appreciate your support. Yoshi

The documentation page you are referencing is for the most recent MATLAB release. The command to open the example you ran is from the latest MATLAB release.
Occasionally, updates made to the documentation and software lead to errors when updated commands are run in older MATLAB versions.
So check which MATLAB release you are using and go to that particular documentation and use that command, that should fix the issue.

Hi Manikanata,
Thanks. I am using the 2024a but still does not work.
One last question is for the page
https://www.mathworks.com/help/sps/ug/custom-transformer-b-h-curve.html
there is a picture below. How can I get actual links instead of picture.

Hi @Yoshi,
Check with 2024a doc command and see if you can open the example.
Regarding getting the links, you cannot open from the documentation page, copy the example command and open it from MATLAB command window and then simulink window opens up, there you can see the model and below you will see these links, you can hover over them and click on them to open.
Thanks!
