You can now model a frequency-dependent inductor in PSpice in three simple steps:
To model the inductance, you will use the GFREQ_FILE component, which supports entries from a CSV file. This component has the following format as entries in a CSV file.
Frequency, Magnitude, Phase
You can extract the frequency vs. inductance data from the graph provided in the inductor’s datasheet and the magnitude can be calculated using the following formula:
Phase for inductance is 90 degrees. Following are the CSV table entries with the magnitude derived using this equation. Save the CSV file on the disk.
Select the GFREQ_FILE component and open its properties to enter the location of your csv file against the FREQ_FILE property as shown below:
Create a circuit and using AC sweep analysis, you can plot the behavior.
