Mode decomposition of conducted noise voltage with synchronized vector signal measurement

抄録

This paper proposes an evaluation method for common mode (CM) and differential mode (DM) of conducted emission in the power line measured with a Vector signal analyzer (VSA). The termination disturbance voltage of the two LISN (line impedance stabilization network) are synchronously measured with a 2ch VSA. The results of vector signal processing in the proposed method in experimentally validation by comparing with the results of conventional method for noise mode separation by using CMDM switch.
