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...
In this paper, a deep bandgap behavior analysis of the vertical cascaded electromagnetic-bandgap (EBG) structure is made. It is shown that the vertical cascaded EBG structure can be decomposed into two EBG structures cascaded horizontally, one with the bigger patches and the other with the smaller patches. The design guidelines of the vertical cascaded EBG structure are drawn. Furthermore, the vertical...
