The mechanism of conducted EMI noise and the characteristics of different modal noise are analyzed in this paper. In order to overcome the difficulty that the traditional method of conducted EMI noise measurement can＇ t diag- nose the EMI noise comprehensively, the conducted noise analyzer is introduced. And its structure and principles are analyzed in detail. In addition, the issue of the conducted noise of a certain type of car navigation system is diagnosed by using it, and the corresponding EMI filter is designed to suppress the conducted EMI noise. The result of experiment verifies the validity of the diagnosis of the conducted noise analyzer.
