Simulation of response of modeled EMI filters to measured or simulated time domain waveforms

This paper demonstrates a procedure for simulating the response of a modeled EMI filter to the conducted emissions of a system using measured or simulated time domain waveforms. The approach presented here deviates from the usual method of analyzing conducted emissions, in that the analysis starts in the time domain rather than in the frequency domain, as would be obtained through spectrum analyzers or EMI receiver measurements.
