In the first place, this article analyzes the principles of electro magnetic interference (EMI) power filter from the aspects of the differential mode and the common mode disturbance. Afterwards, the design requirements of key components in the EMI power filter and the layout principles of filter is investigated. Next, the influence of layout of EMI power filter on the measurement of mains terminal disturbance voltage has been studied experimentally by the lap quality of the filter onto the equipment under test, the distance between the input and output power line of filter, as well as the input cable length of EMI power filter. Finally, we draw the conclusion that the layout quality of power filter has important impact on the measurement of mains terminal disturbance voltage. It means that the related rules should be strictly abided by when the EMI power filter is used to restrain the conducted disturbance.
