Kubera kwa maginito kumakhala ndi mawonekedwe osiyanasiyana a impedance pama frequency osiyanasiyana.Nthawi zambiri, impedance ndi yaying'ono kwambiri pama frequency otsika, ndipo impedance imakwera kwambiri pama frequency apamwamba.Kukwera kwa ma siginecha, kumakhala kosavuta kuti maginito atuluke.Nthawi zambiri, mizere yazizindikiro siyitetezedwa.Mwachitsanzo, basi ya CAN yomwe ndimagwiritsa ntchito pano.Mizere yazizindikiroyi imakhala tinyanga.Antenna iyi imalandira mosalekeza mazizindikiro ozungulira kwambiri.Superposition imasintha chizindikiro chenicheni kuti chitumizidwe.Mphete ya maginito imatha kutulutsa ma siginecha othandiza bwino ndikupondereza ma siginecha osokoneza kwambiri.

Pamaulendo apamwamba kwambiri, inductive reactance imakhalabe yaying'ono, pamene impedance ndi yaikulu, kotero kuti pamene mphamvu ya chizindikiro chapamwamba kwambiri imadutsa maginito, imasandulika kutentha ndi kutulutsa, zomwe zimalepheretsa kupita kwapamwamba. -chizindikiro chafupipafupi ndikupondereza kusokoneza kwa chizindikiro chapamwamba..Kawirikawiri kuponderezedwa kwafupipafupi kumagwirizana ndi chinthu cha ferrite kupondereza.Nthawi zambiri, kutsika kwa maginito permeability, kumachepetsa kupondereza pafupipafupi.Kukula kwakukulu kwa ferrite, kumakhala bwino kupondereza zotsatira.Pamene voliyumu imakhala yosasinthasintha, yaitali ndi yocheperapo imakhala yaitali kuposa yaifupi ndi yowonjezereka.Zopondereza zotsatira zabwino, zing'onozing'ono mphamvu mkati, ndi bwino kupondereza zotsatira.

Mukapondereza kusokonezedwa kwa ma siginoloji wamba, mutha kudutsa siginecha kapena chingwe chamagetsi kudzera pa mphete yathyathyathya ya maginito nthawi yomweyo.Kuti muwonjezere zotsatira, mutha kutembenukira pang'ono pa mphete ya maginito kuti muonjezere ma inductance ndikuwonjezera kuyamwa kwa siginecha wamba.Chizindikiro choipa chilibe mphamvu.

Huizhou Mingda Precise Electronics Co., Ltd. kukhala ndi wopanga okhazikika kupanga EMI odana kusokoneza maginito mphete.Tili ndi mainjiniya omwe ali ndi zaka 20 za TDK R&D komanso luso lopanga.Titha kusintha mphete zamaginito ndi magwiridwe antchito ndi kukula kwapadera malinga ndi zosowa zosiyanasiyana za makasitomala a EMI odana ndi kusokoneza maginito mphete.mankhwala.
