The　electromagnetic　interference　of　power　converters　is　developing　towards　high　frequency.　As　an　important　part　of　the　converter,　the　near　field　coupling　of　magnetic　components　is　more　complicated　at　high　frequencies,　which　is　a　major　and　difficult　research　topic.　Traditional　analyses　show　that　the　near　field　coupling　between　magnetic　components　is　mainly　magnetic　coupling,　but　experiments　and　analyses　show　that　the　electric　field　coupling　between　magnetic　components　has　a　prominent　influence　in　the　high　frequency　of　conducted　emission　(CE).　A　new　near　field　coupling　circuit　model　for　magnetic　components　was　proposed,　and　the　electric　field　coupling,　magnetic　field　coupling　and　field　coupling　loss　were　considered　at　the　same　time,　and　the　parameter　extraction　method　of　the　near　field　coupling　model　was　also　given.　The　measurement　and　the　calculated　results　of　the　established　near　field　coupling　model　were　in　good　concordance　with　the　CE　frequency　band,　which　verified　the　effectiveness　and　accuracy　of　the　proposed　near　field　model.　©　2022　Chin.Soc.for　Elec.Eng.
