Abstract :
In this paper it is shown that conducted interference from a power converter differs when measured with and without a Line Impedance Stabilization Network (LISN). This is problematic as the true Electromagnetic Interference (EMI) of a converter is therefore difficult to characterize. Possible reasons for this difference are discussed showing to the influence of a LISN on measurements.
