This paper deals with the modeling of the EMC filter in wide frequency range. The filter model is created from the models of the EMI filter components. At higher frequencies spurious elements of the components have large influence, which is necessary to describe in the models. EMI filter is composed of the LC low pass structures. Spurious elements of the individual components have a significant effect on the attenuation characteristics.
