Title

Conducted-Emission Modeling for a Switched-Mode Power Supply (SMPS)

Abstract

This paper is focused on the construction of a conducted-emission model for a switched-mode power supply (SMPS). First, the total voltage source is extracted by measurement. Second, the coupling path between the aggressor and the victim is characterized by both simulation and measurement. Finally, the coupled noise to the victim with respect to the extracted total voltage source can be obtained by both simulation and calculation. Both results match well with the measurement result, which validates the robustness of the constructed model.
