Practical Simulation Methods Considering Characteristic Variations of Wires for CISPR 25 Conducted Emission

A method to predict the test results about CISPR 25 without detailed information is proposed. This method could be adaptable for changes of wire types, numbers, and placement topologies. It was confirmed that this method can correspond to the filter difference of DUTs. The average error between simulation and measurements were 4.07 dB with coupled transmission line wire model and 1.28 dB with extracted from measurements wire model in the FM radio band, respectively. This wire modeling methods could be adapted to other tests.
