研究目的
To predict and analyze conducted EMI noise in an automotive LED driver module with DC/DC converters.
研究成果
The study successfully simulated conducted noise from an automotive LED driver module, observing noise in the frequency band of 50MHz to 80MHz. The results help in predicting and debugging conducted noise in the pre-production stage, saving time and effort.
研究不足
Discrepancy between simulation and measurement results due to differences in physical dimensions and cable shape of the implemented automotive LED driver module. The connector model and temperature/frequency dependent properties were not included.
