Abstract：

In　many　cases,　EMI　filter　plays　a　key　role　in　EMC　design.　However,　the　performance　of　EMI　filters,　especially　in　high　frequency,　is　often　different　from　previous　estimates.　Based　on　this　situation,　this　paper　first　theoretically　calculates　the　performance　of　EMI　filter,　and　then　analyzes　the　effect　of　the　parasitic　parameters　of　each　component　of　the　filter　and　its　near-field　coupling　on　the　filter　performance.　Based　on　these　analyses,　high　frequency　equivalent　model　of　the　first-order　π　filter　is　completed,　which　verifies　the　rationality　of　the　analysis.　©　2021　IEEE.
