Abstract

In this study, a simple conducted noise modeling method based on classical frequency domain modeling concept is developed. Compared with conventional methods, the accuracy of noise source model in the proposed modeling method is improved by using S-shape waveform model with the consideration of high frequency ringing waveforms. The parameters of noise source model are extracted on the basis of experimental measured waveforms. Finally, the accuracy of the proposed conducted noise modeling method is validated on a DC-DC boost converter, the comparison between measured and calculated conducted noise spectra show that the low frequency (0.15 MHz-2 MHz) noise peaks as well as high frequency (10 MHz-30MHz) peak can be accurately predicted.
