Abstract For the measurable electromagnetic interference, supported by experimental data and based on the system identification, a new modeling approach for the interference of electronic devices is presented. It solves the contradiction between model's complexity and accuracy, which exists in the traditional process of modeling the internal circuits of electronic devices. The parameters of filter with designed structure can be optimized by this new model with tolerant error range, and the parasitic parameters of electronic components can be considered at the same time. Therefore this modeling method makes up the drawbacks of the previous electromagnetic susceptibility (EMS) analysis and filter design mainly relies on substantial experiments but lacks system simulation analysis.
