Kodi pali kusiyana kotani pakati pa njira yodziwika bwino Choke ndi masiyanidwe amachitidwe modutsa? Gvey akatswiri opanga ma inductor kuti anene mwachidule.
Chokonda wamba, chomwe chimadziwikanso kuti Common mode Choke, chimagwiritsidwa ntchito kusefa Zizindikiro za EMI posintha magetsi pamakompyuta.Pakapangidwe ka makhadi, opangira mawonekedwe amachitidwe amtundu wa fyuluta ya EMI, yomwe imagwiritsidwa ntchito kupondereza mawonekedwe amagetsi opangidwa ndi mzere wothamanga kwambiri.
Kusiyanitsa mawonekedwe inductance ndi mtundu wa inductance yomwe imatha kukana kusokonekera kwapafupipafupi kwamachitidwe a masiyanidwe, otchedwanso masiyanidwe amachitidwe kutsamwa koyilo.Pali mitundu itatu yazida zapakati pazosiyanitsa mitundu ya ma inductors. Mtengo wake wagawo lililonse la Fe-Si-Al maginito ufa pakati ndi yotsika kwambiri, chifukwa chake ndioyenera kupanga ma inductors apachiweniweni. Mtengo wa Fe-Ni 50 ndi Fe-Ni Mo maginito ufa pachimake ndiwokwera kwambiri kuposa Fe-Si Al maginito ufa pachimake, womwe uli woyenera kwambiri zogwiritsa ntchito zankhondo komanso nthawi zina zokhala ndi mphamvu yayikulu komanso magwiridwe antchito.
Kusiyanitsa pakati pamafupipafupi amachitidwe ndikusiyanitsa kwamachitidwe inductance
1.Common mumalowedwe inductance kumulowetsa amakhala kawiri waya bidirectional; masiyanidwe mode inductors ali chilonda mbali imodzi.
2.Fyuluta inductor yomwe imapondereza kusokonekera kwamachitidwe wamba amatchedwa wamba-modelo inductor; Fyuluta inductor yomwe imaletsa masiyanidwe amachitidwe osokoneza amatchedwa masiyanidwe amachitidwe inductor.
3.Kufalikira kwamachitidwe kwamagulu awiri am coil okhala ndi ma coil ofanana, m'mimba mwake momwemo mawaya ndi kupingasa komwe kumayambira pachimodzi chimodzimodzi; Kusiyanitsa kwamachitidwe inductance ndi bala la koyilo kuzungulira pachimake.
4.Common mode sign: manambala awiri ofanana amapangidwa pamzere wa zero ndi mzere wamoto motsatana; Chizindikiro chazosiyana: choyenera kugwiritsidwa ntchito mdera lofananira.
Makhalidwe a 5.Common mode inductance: chifukwa magulu awiri am coil pachimake chimavulazidwa mbali zosiyana, ndiye kuti pachimake saopa machulukitsidwe.High conductance ferrite zakuthupi ndizomwe zimagwiritsidwa ntchito kwambiri pamagetsi pamsika.
Pamwambapa ndi njira yodziwika bwino yomwe imatsamwitsidwa komanso kusiyanasiyana kwamachitidwe inductance, chiyembekezo chitha kukuthandizani.Ndife akatswiri opanga ma inductor ochokera ku China, takulandirani kuti mufunse!
Chithunzi cha njira yodziwika bwino yatsamwa:
