The electromagnetic field coupling at low frequency between electromagnetic interference (EMI) sources of switched-mode power supplies (SMPS) and a victim circuit is represented by two-port networks. The mutual impedance between source and victim circuit is calculated by the induced EMF method. The two-port representation of the field coupling allows the noise voltage on a circuit victim to be predicted. As a reference victim circuit circular loops outside the source are considered. The approach is applied to a SMPS and validated through experimental measurements.

Abstract
The electromagnetic field coupling at low frequency between electromagnetic interference (EMI) sources of switched-mode power supplies (SMPS) and a victim circuit is represented by two-port networks. The mutual impedance between source and victim circuit is calculated by the induced EMF method. The two-port representation of the field coupling allows the noise voltage on a circuit victim to be predicted. As a reference victim circuit circular loops outside the source are considered. The approach is applied to a SMPS and validated through experimental measurements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
