The “solver configuration” block in the model has the sample time as 0.001 sec. So, the “scope” block will observe the value of current at the interval of 0.001 seconds I.e., the frequency of the “scope” block is 1000 Hz. The “scope” block will be accurate if the frequency of “scope” block is more than frequency of “current source” block.
To get the accurate results for the 40 KHz frequncy of current source kindly set the frequency of “scope” block more than 40 KHz. This can be done by setting the “Sample time” block parameter of the “solver configuration” block as lower than 0.000025 seconds.
Hope this helps.
