A study on electromagnetic interference analysis and suppression method for traction system of high-speed EMU
According to the complexity of electromagnetic interference of traction system of high-speed EMU
and in combination with the design of the vehicle system
the EMI coupling paths of traction system were analyzed. Based on the equivalent interference source method
a calculation model for the common-mode interference of the system was established. The high-frequency test and modeling of the EMU traction system and the simulation prediction of the interference current were completed
and the accuracy of the theoretical model was verified by the measured results. Finally
according to the analysis of the influencing factors of electromagnetic interference of traction system
an interference suppression method was proposed
and the effectiveness of each suppression measure was verified by simulation or test.
