modeling of non linear effects in ferromagnetic cores of inductive components in high power filters

Pulse power sources, causing high level noise are used in most of modern electronic systems. So modeling and optimization of electronic filters became more important. Diploma thesis contains modeling of non linear effects in ferromagnetic cores of inductive components in high power filters. For this work measurement setup and method were developed, which allows to define dependance between magnetic permeability of toroidal core and magnetic field. Also was constructed second measurement setup which allows to measure filter in active mode, on high current. Analysing modeling results and comparison with measurements helped to develop methodology which allows to predict filter behavior for high current operating conditions .
