Common Mode Inductor kapena Choke
Ngati ma koyilo olowera mbali imodzi azunguliridwa mozungulira mphete ya maginito yopangidwa kuchokera ku chinthu china cha maginito, magetsi akamadutsa, maginito amapangidwa mu koyilo chifukwa cha kulowetsa kwamagetsi.Pazizindikiro zamitundu yosiyanasiyana, maginito otuluka amafanana kukula kwake komanso kosiyana kolowera, ndipo awiriwo amathamangitsana, zomwe zimapangitsa kuti pakhale kusiyana kochepa kwambiri kopangidwa ndi mphete ya maginito.Kwa ma siginecha wamba, kukula ndi komwe kumachokera ku maginito komwe kumapangidwa kumakhala kofanana, ndipo kukwera kwakukulu kwa ziwirizi kumapangitsa kuti maginito amphete kwambiri.Khalidweli limachepetsa kukhudzika kwa ma inductance wamba pamasigino osiyanitsira ndipo limakhala ndi kusefa kwabwino polimbana ndi phokoso wamba.
Inductor wamba wamba kwenikweni ndi fyuluta ya bidirectional: mbali imodzi, imayenera kusefa njira wamba yosokoneza ma elekitiroma pa mzere wa siginecha, ndipo mbali inayi, imayeneranso kupondereza kusokoneza kwa ma elekitirodi kuti isatulutse kunja kuti ipewe. kukhudza magwiridwe antchito anthawi zonse pazida zina zamagetsi pamalo omwewo amagetsi.
Ubwino watsatanetsatane wawonetsedwa pansipa:
(1) Annular maginito pachimake ali wabwino maginito coupling, kapangidwe yosavuta ndi mkulu kupanga bwino;
(2) High ntchito pafupipafupi, mkulu mphamvu kachulukidwe, pafupipafupi pakati pa 50kHz ~ 300kHz.
(3) Makhalidwe abwino kwambiri otenthetsera kutentha, okhala ndi malo okwera kwambiri mpaka kuchuluka kwa voliyumu, njira yayifupi kwambiri yotenthetsera, yabwino kutulutsa kutentha.
(4) Kutayika kotsika kwambiri kolowera;
(5) Makhalidwe apamwamba a impedance ya high-frequency inductance;
(6) Ubwino wabwino wokhala ndi mtengo wokwanira;
(7) Chikhalidwe chokhazikika.
(1) Kugwiritsa ntchito ma frequency apamwamba a ferrite pachimake, kupendekera koyima kwa waya wathyathyathya;
(2) magawo ogawa yunifolomu ndi kusasinthika kwabwino kwa magawo;
(3) Kupanga zodziwikiratu ndi inductance yayikulu komanso yayikulu zitha kukwaniritsidwa;
(4) Ndi ntchito zapamwamba zamakono komanso zabwino kwambiri zotsutsana ndi EMI;
(5) Kugwirizana kwa magawo omwe amagawidwa;
(6) Kuchulukira kwakukulu kwamakono, mafupipafupi, kuthamanga kwakukulu;
(7) Kutentha kwakukulu kwa Curie;
(8) Kutsika kwa kutentha kwapansi, kutayika kochepa, etc.
Nthawi zambiri amagwiritsidwa ntchito posinthira magetsi pamakompyuta kuti azisefa ma siginecha amtundu wa electromagnetic interference.Pamapangidwe a board, ma inductors wamba amagwiranso ntchito ngati zosefera za EMI kuti zithetse ma radiation ndi kutulutsa kwa mafunde amagetsi opangidwa ndi mizere yothamanga kwambiri.
Amagwiritsidwa ntchito kwambiri pamagetsi a air conditioner, magetsi a TV, magetsi a UPS, etc.
