Abstract The high-frequency model of the various parts and the specific common mode conducted interference transmission path of the high power three-level dual frequency control system are studied.First the high-frequency models of common mode interference sources,DC busbars,cables,and induction motor are established respectively and the common mode conducted interference transmission path is analyzed in detail.Then Matlab is used to simulate the high-frequency model of the frequency control system,and the experimental platform within the engineering center is used to complete the relevant test.The correctness of the theoretical analysis and the models is verified by the results of the simulation and experiment.Finally a filter is designed to significantly suppress the interference.

Key words： Dual three-level common mode interference double Fourier high-frequency model
