Abstract
This paper introduces a method to design the external electromagnetic interference (EMI) filters for switching power supplies. The thesis expounds theory and calculates the filter insertion loss, then analyses the impact of the source impedance and the components model on insertion loss. According to the conducted EMI waveform of switching power supply, we make the corresponding EMI filter, and verify the feasibility of design method with experiments.
