Abstract

The invention discloses a coupling and decoupling characteristic determining method of a V-type line impedance stabilization network and belongs to the electromagnetic compatibility conducted emission testing technical field. According to the method, the coupling and decoupling characteristics of the V-type line impedance stabilization network can be calculated and analyzed; and as for a line impedance stabilization network (LISN) of which the component parameters are known, whether the coupling and decoupling characteristics of the LISN satisfy work requirements can be predicted in the aspect of trend. The method can predict and judge the coupling and decoupling characteristics of the LISN according to which a third party metering check unit does not carry out metering, and plays a role of guiding the design and development of novel LISN which can better satisfy requirements.

Description

technical field

[0001] The invention relates to a method for determining the coupling and decoupling characteristics of a V-shaped linear impedance stabilization network, through which the coupling and decoupling characteristics of a V-type linear impedance stabilization network can be analyzed, and the correctness and reliability of the analysis method are verified by experiments , belongs to the technical field of electromagnetic compatibility conduction emission. Background technique

[0002] In the electromagnetic compatibility conduction emission test, due to the different types of connections of the tested product, the power supply impedance at different positions varies greatly, resulting in drastic changes in the load terminal impedance of the tested product, which directly affects the test results of the tested product’s power line conducted emission . In order to make the conducted emission test results of power lines measured in different sites comparable, a line...
