SIMPLIS Technologies will attend APEC 2025 in Atlanta, GA, on March 16-20, 2025.
Please visit us at Booth #822 on the Main Exhibition Hall Floor.
We will be presenting an Exhibitor Seminar session on the topic of "Simulating the Conducted EMI Performance of a Switching Power Supply":
Using the new LISN block (available in SIMetrix/SIMPLIS v9.20b+), we show how to measure the conducted EMI performance of a switching power supply. A comparison of the measured results against an EMI specification is performed using a Design Verification Module (DVM) post-processing script implemented in Python, the results of which are used to determine the attenuation requirements for an EMI filter. With those requirements, we calculate the EMI filter component values utilizing the optimizer function in SIMetrix/SIMPLIS. We then measure the EMI performance of the resulting combination of power supply and EMI filter to verify that the performance meets the EMI specification. Finally, we verify that the power supply with EMI filter meets system stability requirements.
More information on the time and location of the session will be provided when available.
