Current probe method applied in conductive electromagnetic compatibility (EMC)

In this paper, the current probe measurement method applied in conductive EMC for determination of power-line EMI source impedance is presented. The theoretical analysis and experimental example are described in detail. Additionally, processing on how to measure the conductive EMI noise , i.e. common mode (CM) and differential mode (DM) noise is also introduced based on noise discrimination network. Results show that the current probe measurement method in paper is an effective tool for noise source analysis and noise suppression in conductive EMC engineering.
