Abstract: Development of electric vehicles is promoted by the increasing problems about the severe shortage of oil resources and serious environment pollution at present. The interference produced by the new high-power electronic equipment in electric vehicles will have influence on the equipment that is attached to it, especially the effect it has on the control circuit cannot be ignored. In this paper, in the four typical working states of electric vehicles, research on the conducted interference current features on the control line of DC converter system is done, reasons for interference coupling to the control line are analysed, and the conclusion is drawn that the value of interference current on the control line in starting state and charging state is the maximum and that value decreases in high-speed state and idle-speed state.
