Variable Impedance in Measuring EMI Filter's Insertion Loss

Original language description

This paper deals with measuring EMI supply filters. There is explained the measuring configuration which is now design for the measuring of insertion loss of EMI filters. The main problem in this type of measuring is that the filter is normally designedfor the constant input and output impedances which is usually 50 ohms. But the main question is what does it happen if we connect this filter into the low-voltage power supply network. So I designed the simple circuits which try to simulate the impedancee of the low-voltage power supply network. And these circuits were used in measuring of the EMI supply filter. Now these circuits are designed only for measuring the asymmetric insertion loss and the life cycle of the output impedance is design in harmony with output impedance of the circuits which is very often called LISN (Line Impedance Stabilising Network). This circuit we can find in the measuring devices which are able to measure the interference that is circulated in network's wir

Využití proměnné impedance při měření vložného útlumu odrušovacích filtrů

Czech description

Článek se zabývá návrhem specifických podmínek pro měření napájecích odrušovacích filtrů. Jde o podmínky, které simulují chování impedance napájecí nízkonapěťové rozvodné sítě. Ke konstrukci takovéhoto články byly použity poznatky z obvodů LISN (umělá síť), které jsou používány při měření rušení šířícímu se po vedení.
