This article studies the mechanism and suppression methods of conducted EMI noise. First, it explains the generation mechanism of conducted noise, analyzes the difference between common mode conduction and differential mode conduction, and establishes a common mode conduction noise model and a differential mode conduction noise model. The methods for suppressing conducted EMI noise in different situations are finally verified through conducted noise suppression experiments to verify the correctness and reliability of the theory. The research in this article provides a theoretical basis for the actual EMC rectification.
