Research on Conducted EMI Modeling and Simulation for Automotive DC-DC Converters
In vehicular power systems, DC-DC converters are one of the primary sources of electromagnetic interference (EMI), making their EMI characteristics a subject of significant concern. This paper presents a conducted EMI modeling study for a specific automotive DC-DC converter. High-frequency circuit models of MOSFETs, capacitors, and transformers are established, and parasitic parameters of PCB traces are extracted to develop a system-level conducted EMI simulation circuit model. The study demonstrates that modeling and simulation analysis can effectively predict the EMC characteristics of DC-DC converters, providing theoretical support for the design and optimization of power systems.
