In order to effectively suppress the conducted electromagnetic interference（EMI） noises,an optimized noise separating network and a noise source impedance extraction method with single current probe were proposed.Decision-making parameter modeling of technical and economic integration and the synthetic apparatus of EMI noise processing were applied for synthetic solution design.Tests were set up for CMRR of noise separating network and noise source impedance extraction using single current probe,and the synthetic system for conducted EMI noise processing was developed.The results show that the synthetic solution scheme is valid and efficient for noise separating and source impedance extraction.Technical and economic optimization are achieved in this scheme.The scheme is well realized in the synthetic system proposed.The results provide references for conductive electromagnetic compatibility.
