Thewamba mode inductorimagwiritsidwa ntchito mudera la CAN, ngakhale silingasinthidwe bwino mu EMC. Mainjiniya ambiri amawonjezera mabwalo ozungulira CAN. CAN chip ili ndi mphamvu yotsutsa-static komanso yanthawi yochepa. Kaya ndiwamba mode inductorziyenera kuwonjezeredwa ku CAN Circuit imaganiziridwa makamaka kuchokera ku mawonekedwe a electromagnetic

Pali mabwalo awiri otseguka mu CAN, omwe amatha kuyendetsa basi kupita pamlingo wokulirapo, pomwe mulingo wocheperako umazindikirika kudzera pakutulutsa koletsa ma terminal.

Kupatsirana kosiyana kwa basi kumakhala ndi luso loletsa kusokoneza wamba, Kusokoneza wamba kuchokera kunja kumatha kuthetsedwa bwino ndikuchotsa mabwalo awiri amkati otseguka. Komabe, mabwalo awiri otsegukawa sali ofananira bwino ndipo akukwera mwachangu, zomwe zimabweretsa zovuta zama electromagnetic kukhudzana ndi EMC.

Titha kuwona kuchokera ku oscilloscope kuti mawonekedwe a basi ndi ofanana kwambiri, ndipo mafunde, magetsi osasunthika, gulu la EFT lopumira komanso chitetezo chokwanira ndizabwinobwino. Komabe, poyesa kufalitsa, ziwonetsa zolakwika. Basi yomwe imawoneka bwino imatumiza zosokoneza kunja.

Mu dera la CAN, ngati mukufuna kuti kuyankhulana kwa basi kukhale kodalirika komanso kuthetsa vuto la EMC la mawonekedwe, kuwonjezera pa CAN transceiver chip, njira ina ndiyo kuwonjezera zotumphukira ku mawonekedwe a CAN.Common mode inductorndi chisankho chabwino. Ma transceivers ambiri a CAN adzadutsa malire osokoneza.

Common mode inductorimatha kuchepetsa chipwirikiti, koma mabasi kuphatikiza makina ojambulira wamba angayambitse vuto la ma resonance ndi kanthawi kochepa. Common mode inductor adzakhala ndi parasitic inductance, kukana ndi zinthu zina zomwe zingakhudze khalidwe la chizindikiro cha basi, zomwe zimabweretsa kuwonongeka kwa chizindikiro. The inductor wamba ali ndi inductance yayikulu. Ikagwiritsidwa ntchito pa mawonekedwe a transceiver, plug yotentha ndi zina zogwirira ntchito, malekezero awiri a inductor yamtundu wamba amapanga magetsi apamwamba, omwe angawononge CAN transceiver. Chifukwa chake, mphamvu ya resonance ndi yanthawi yochepa yomwe idayambitsidwa chifukwa chake iyenera kuganiziridwabe pakugwiritsa ntchito.

Ngati muli ndi chidwi, chonde omasukakulumikizana ndi MingDakuti mumve zambiri.
