Determination of a relevant criterion to characterize differential conducted perturbations generated by low frequency converters

This paper demonstrates that the slope is not an appropriate parameter to characterize a waveform regarding conducted electromagnetic perturbations. On the other hand, a relevant criterion is made conspicuous: it defines the maximum slope deviation between two segments forming a signal. This criterion is validated by a waveform with a maximum slope of 400 mA//spl mu/s.
