The paper deals with the EMI filter models for the calculation of the insertion loss characteristics. The insertion loss is in fact the basic EMI filter property. Unfortunately it is not easy to precisely define and measure this parameter in a wide frequency range due to variability of terminating impedances. The uncertainty of the potential impedance termination really complicates the measurements and also comparison of the performance of filters. A model with spurious components is introduced in this paper. The procedure model design is also added up. The spurious components make together with the real ones form resonant circuits. The resonance frequencies make breakages in the insertion loss characteristic. Their resonance frequencies were identified by the analysis of equivalent circuits of the filter for different measuring systems. The calculation of the values of spurious components, based on knowledge of resonance frequencies, is mentioned at the end of the paper. |
