Method and device for providing a behavior model for the simulation of electromagnetic interference emissions from an electrical or electronic component

摘要

The invention relates to a method for providing a behavior model, in particular an EMC behavior model, in the form of model data for the simulation of an electrical or electronic component (1) described by the behavior model in a simulation device, the behavior model showing the behavior at one or more electrical connections (A1, A2) of component (1) describes the electrical behavior at each of the connections (A1, A2) of the component by a connection equivalent circuit as the effect of complex, frequency-dependent electrical quantities of passive electrical components, in particular admittances or impedances , and a source element, in particular a voltage and / or a current source, is described, the behavior model by measuring (S1) an impedance / admittance matrix in the passive, unloaded state of the connections using a network analyzer (2) and by determining (S2) the complex n, frequency-dependent electrical quantities of the source elements is determined by measuring the currents and / or voltages at the connections under a single load condition.
