Fyuluta yotsika yaying'ono yofananira ndi coil yokhazikika | KHALANI BWINO

Njira zofananira , zomwe zimadziwika kuti choko wamba, zimagwiritsidwa ntchito pofalitsa ma kompyuta pamakompyuta kuti athe kunyalanyaza zofananira. Mu kapangidwe ka gulu lowongolera, chizolowezi chofala chimagwiranso ntchito ndi fyuluta ya EMI, yomwe imatha pewani mafunde amagetsi amagetsi omwe amayamba chifukwa cha mzere wothamanga kwambiri kuti asatumize kuzinthu zakunja kwa radioactive.

Chifukwa chiyani njira zodziwika bwino zimatsutsana ndi EMI?

Kuti mumvetse izi bwino, ndikofunikira kuti muyambe kusanthula kapangidwe kazomwe zimakhazikika.

Zosefera zaposachedwa kwambiri zodzipanikiza ndi USB wamba, La ndi Lb ndizomwe zimapangidwira. Ma coil awiri amangiriridwa pa coil yofananira yomwe ili ndi kuchuluka kofanana kotembenukira ndimayendedwe am'mbali (kubwerera kwa koyilo inductor). dera limadutsa njira yodziwika bwino, mafunde oterewa amapanga maginito mosakanikirana ndi coil ya inductor yomwe ili ndi gawo limodzi la Angle ndikutsutsana. Pakadali pano, mayendedwe onse azizindikiro a data amakhala ndi ma coil resistors (ndi ochepa of the absorption shock chifukwa cha kuyenda inductance); Pamene njira wamba yomwe ikuyenda ikadutsa koyilo, chifukwa njira wamba yomwe ili munjira imodzimodzi, koyiloyo imapanga maginito mbali yomweyo, komanso kuyiyika koyipa kwa koyilo Idzakulirakulira, ndikupangitsa kuti koyiloyo ikhale ngati mphindikati yayikulu, motero kumapangitsa kuti mayamwidwe amveke mwamphamvu.

Chifukwa chake, mawonekedwe owoneka bwino apano adzachepetsedwa ndi koyefishienti kuti ikwaniritse zomwe zosefera ziliri, Pamenepo, ngati mathero amodzi a fyuluta yotsika yolumikizidwa ndi chizindikiritso choloza ndipo mathero ena alumikizidwa ndi chida chomwe chakhudzidwa ndipo makina, La ndi C1, Lb ndi C2 apanga ma fyuluta awiri otsika omwe amatha kugwiritsa ntchito zizindikiritso zamagetsi zamagetsi panjira yopita kuzizindikiro zotsika kwambiri.

Dera silingathe kupondereza kufalikira kwa ma elekitiroma akunja, koma limathandiziranso kuchepetsa mphamvu yamagetsi yamagetsi yamagetsi yomwe imayambitsidwa ndi mzere woonekera pakugwira ntchito kwa koyefishienti, potero amachepetsa kuwonongeka kwa chizindikiritso chotsutsana ndi mphamvu yolimba.

Pakadali pano, njira yodziwikiratu yopangidwa ndi kampaniyo ili ndiubwino wopondereza phokoso pafupipafupi komanso njira zopewera, njira yofananira, kutsika kozungulira kozungulira, kukula kocheperako, kosavuta kugwiritsa ntchito, kukhazikika bwino, kosavuta kugwiritsa ntchito komanso mtundu wapamwamba Amagwiritsidwa ntchito kwambiri pakupanga zida zamagetsi zamagetsi, ma frequency angapo osinthira, chosinthira chosinthira, chosinthira chosasunthika, etc.

Palinso USB ndi ferrite pachimake wamba-mode-kutsamwa koyilo / EMI fyuluta inductance, kukhala ndi mndandanda wambiri wokutira, kubisa phokoso kwabwino komanso njira zothanirana, magwiridwe anthawi zonse amtundu wa phokoso komanso chizindikiritso chotsika cha phokoso, kulepheretsa chizindikirocho kusokonekera phokoso laphokoso, siginecha ya data yothamanga osati mapindikidwe, kukula pang'ono, kukhazikika bwino, kugwiritsa ntchito bwino, maubwino apamwamba.

Zingwe za USB zamakompyuta anu ndi zotumphukira, zingwe za IEEE1394 zama DVC ndi ma TV oyikapo mabokosi, ndi ma sign a zomvera zamagetsi opangira ma LCD ndi ma voltages ogwirira ntchito pansi.

Ndiko kuyambitsa kwa fyuluta yotsika yapazomwe zimafikira anthu wamba. Ndife oyembekezera , ngati mukufuna kugula kapena kusintha, landirani kukafunsira ~
