Hello ADI Team,
I am trying to replicate the same circuit shown in " How to Get the Best Results Using LTspice for EMC Simulation—Part 1" (https://www.analog.com/en/technical-articles/how-to-get-the-best-results-using-ltspice-part-1.html) for understanding the use of LTspice in EMC simulation. I had successfully made circuit and added plot settings and all other steps but I am getting some different FFT results compare to shown in application note (Result of Figure8/Figure11). I believe there is some ESL/ESR values I need to change in component properties which is not visible in snapshot of the circuit. Please find attached files for the same.
Can you please provide same LTspice circuit shown in the application not so that I can use that for further testing ?
Hello ADI Team,
Have you got a chance to check my above request ?
Hi there,
I'm not the original author of the article but I have played around with the LTspice simulation but with the CM choke added. You can try the ESR/ESL values in the attached. My simulation also includes behavioral sources to get DM and CM noise without needing to type the 500000*... in the plot window.
