Passive components, in particular capacitors and coupled inductors, are the most important parts of electromagnetic interference (EMI) filters. The parasitic elements of these components and the impact of temperature on their frequency behavior are very significant and should not be neglected; these unwanted effects have a major impact on EMI filter performances. In this paper, characterization test-benches...
This paper proposes a black box approach which synthesizes lumped circuit model of the Foster type for a frequency-dependent characteristic element by the least squares method systematically. However there are two numerical difficulties to model them. One is the numerical stability problem which comes from limitation of effective numerical digits of data especially for wide frequency band ranges....
