Abstract
Passive EMI filters are commonly used in order to meet the requirements of related standards. In the case in question, the application of passive filters has to ensure the placement of measurement results, taken in normalized arrangement, below limit lines. Often EMI filter design is limited to the selection of the ready-to-use filter of the appropriate rated current, however in this case the solution is usually not cost-effective and might bring about results contrary to those intended. The external electromagnetic compatibility of the equipment at the point of use requires in-depth analysis of the interference current flows as well as knowledge of the frequency characteristics of the real elements constituting the parts of the filter. In this chapter there are presented the results from the measurement of the parameters of real filter components and the analysis of the influence of the inductive filters on various aspects concerning both internal and external compatibility of the system.
