The suppression of the new conducted EMI noise which is affected by electromagnetic field is studied in this paper. The difference of normal filters and EMI filters is analyzed specifically, and on the basis of analysis of the typical filter, the new model of conducted EMI filter is proposed, of which the structure and suppression principle are analyzed, and this filter can suppress the new conducted EMI noise. In the end, as for the new conducted noise of a certain type of credit card machines, both of the two kinds of EMI filters are applied to suppress its conducted noise. The result of ex- periments shows that the new model EMI filter proposed in this paper can well suppress the new conducted EMI noise.
