Modeling of EMI filters

Nova days one from very important solved problems in practise there is an increasing of immunity of electronic systems. The paper deals with method of model synthesis, which is useful in area of EMC frequency filter design and optimization. Different types of EMC equivalent models here are discussed. The method of synthesis and optimization of equivalent model with required transfer response is declared in example of EMC power filter. The resulting influence of mismatched conditions on filter performance in entire working frequency range is discussed in some details
