The proposed filter characterization method makes it useful to predict EMI filter performance when the filter is used in a practical power supply. High frequency parasitic effects can also be predicted using this method. An impedance/gain-phase analyzer is needed for this approach.read more

Systematic design of EMI-filters for power converters
A. Nagel,R.W. De Doncker +1 more
TL;DR: In this article, a systematic approach is described to take guesswork out of filter design, which is divided into three steps: (1) measurement of the impedance and amplitude spectrum of the noise source; (2) determination of the sink impedance; (3) calculation of the filter component values to fulfil a given limit curve with least costs for the overall filter.
