Hi,
I have a question regarding PSIM Signal Analyzer. Does it give the measurements in Quasi peak or average? If not, what would be way to convert the peak measurement into QP/average using PSIM.
Any help/comment will be appreciated.
@NikosDimitrakopoulos any insight on this will be helpful
Dear @ashikamineee08, Thanks for reaching out! I believe you are referring the Signal Analyzer block for Conducted EMI measurements:
The outputs of this block are actually time domain signals:
You have the option from within Simview to directly apply an FFT. However, the FFT is neither a peak nor a quasi‑peak algorithm. It is a signal‑processing method used to transform time‑domain data into the frequency domain. FFT is not the best method to investigate EMI results as it often suffers form spectral leakage. This is why windowed-FFT methods are preferred instead and this where the concept of peak/quasi peak/average detection applies. Unfortunately, PSIM doesn't offer an inherent windowed-FFT algorithm. That said, you can connect PSIM simulations and PSIM results with Python to post process as needed: PSIM & Python Hope this helps! BR Nikos Dimitrakopoulos
