| Summary: | In this dissertation, we designed an electromagnetic interference (EMI) filter by
combining PCB onboard coils with an E-shaped magnetic core, and experimen
tally validated its performance in both low-frequency and high-frequency ranges.
The reflection coe cient curves indicated that the proposed filter e↵ectively at
tenuates high-frequency noise. Furthermore, we developed a simplified model of
the EMI filter and conducted theoretical simulations, confirming its e↵ectiveness.
Additionally, experimental comparisons were performed across di↵erent configu
rations, and we analyzed the relationship between filter performance and these
configurations. The results provided insights into how various design settings
influence the filter’s behavior, o↵ering subjective interpretations of the observed
phenomena |
