Imikhiqizo
I-Common Mode Inductor noma Choke
Uma ipheya yamakhoyili asendleleni efanayo ezungeza iringi kazibuthe eyenziwe ngento ethile kazibuthe, lapho ukushintshana kwamandla kudlula, ukugeleza kazibuthe kukhiqizwa kukhoyili ngenxa yokungeniswa kukazibuthe.Kumasignali emodi yokuhlukanisa, ukuguquguquka kazibuthe okukhiqizwayo kuyefana ngobukhulu futhi kuphambene ngalapho kuya ngakhona, futhi okubili kuyakhanselana, okuholela ekuphazamisekeni kwemodi encane kakhulu yokuhluka okukhiqizwa indandatho kazibuthe.Kumasignali emodi evamile, ubukhulu nesiqondiso se-flux kazibuthe ekhiqizwayo kuyafana, futhi ukuphakama kwakho kokubili kuphumela ekuvinjweni okukhulu kwemodi evamile yendandatho kazibuthe.Lesi sici sinciphisa umthelela wemodi evamile yokungena kumasignali emodi yokuhlukanisa futhi sisebenza kahle ngokuhlunga ngokumelene nomsindo wemodi evamile.
I-inductor yemodi evamile empeleni iyisihlungi se-bidirectional: ngakolunye uhlangothi, idinga ukuhlunga imodi evamile yokuphazanyiswa kozibuthe emugqeni wesignali, futhi ngakolunye uhlangothi, idinga futhi ukucindezela ukugxambukela kwe-electromagnetic ngokwayo ekuphumeni ngaphandle ukugwema. ezithinta ukusebenza okuvamile kwamanye amadivaysi e-elekthronikhi endaweni efanayo ye-electromagnetic.
Izinzuzo ezinemininingwane ziboniswa ngezansi:
(1) I-annular magnetic core inokuhlangana okuhle kwe-electromagnetic, isakhiwo esilula nokusebenza kahle kokukhiqiza okuphezulu;
(2) Imvamisa yokusebenza ephezulu, ukuminyana kwamandla aphezulu, imvamisa phakathi kwe-50kHz ~ 300kHz.
(3) Izici ezinhle kakhulu zokukhipha ukushisa, enendawo ephezulu ukuya kusilinganiso sevolumu, isiteshi sokushisa esifushane kakhulu, esilungele ukuqeda ukushisa.
(4) Ukulahlekelwa kokufaka okuphansi kakhulu;
(5) Isici esiphezulu se-impedance ye-high-frequency inductance;
(6) Ikhwalithi enhle enezindleko ezifanele;
(7) Isakhiwo esizinzile.
(1) Ukusebenzisa i-high frequency ferrite core, ukuma okuqondile kocingo oluyisicaba;
(2) Imingcele yokusabalalisa okufanayo kanye nokuvumelana okuhle kwamapharamitha;
(3) Ukukhiqizwa okuzenzakalelayo nge-inductance enkulu yamanje kanye nephezulu kungafinyelelwa;
(4) Ngokusebenza okuphezulu kwamanje nokuhle kakhulu kwe-anti-EMI;
(5) Ukuhambisana kwemingcele esabalalisiwe;
(6) Ukuminyana okuphezulu kwamanje, imvamisa ephezulu, i-impedance ephezulu;
(7) Izinga lokushisa eliphezulu leCurie;
(8) Ukukhuphuka kwezinga lokushisa eliphansi, ukulahlekelwa okuphansi, njll.
Okuvame ukusetshenziswa ekushintsheni kwamandla ekhompyutha ukuhlunga amasiginali wokuphazamiseka kagesi wemodi evamile.Ekwakhiweni kwebhodi, ama-inductors emodi evamile aphinde asebenze njengezihlungi ze-EMI ukucindezela imisebe kanye nokukhishwa kwamagagasi kagesi akhiqizwa imigqa yesiginali yesivinini esikhulu.
Isetshenziswa kakhulu ekunikezeni amandla kagesi we-air conditioner, ugesi we-TV, ukunikezwa kwamandla kwe-UPS, njll.
