Abstract: This paper deals with the approximate worst-case test method for testing the insertion loss of the EMI filters. The systems with 0.1 Ω and 100 Ω and vice versa impedances are usually used for this testing. These measuring systems are required by the international CISPR 17 standard. The main disadvantage of this system is the 0.1 Ω impedance transformer. The dynamic range for the transformation from the 50 Ω, which is most common matched impedance for the measurement setups, to 0.1 Ω is very large. It is not easy to produce such transformers with this high impedance transformation ratio. These transformers have usually very narrow bandwidth and require the several of these transformers for one filter measurement. This paper discusses the alternative system with 1 Ω and 100 Ω impedances and also vice versa for the measuring the performance of the RFI filters. The modification itself was done according to the mathematical model for t!
he first estimation of the filters' performance and the optimal configuration with 1 Ω and 100 Ω impedances was chosen according the calculated results as the optimal compromise. The performance of this system was tested on several filters and the obtained data are depicted, too. The performance comparison of several filters in the asymmetrical and symmetrical systems is also included. The performance of alternate worst-case system is discussed in the conclusion.
