Imo yesiqhelo yangoku: Ipere yemiqondiso (okanye ingxolo) enobukhulu obufanayo kunye nesalathiso kwiperi yemigca yophawu olwahlukileyo. Kwisekethe. Ngokuqhelekileyo, ingxolo yomhlaba ihanjiswa ngokubanzi ngendlela eqhelekileyo yangoku, ngoko ikwabizwa ngokuba yingxolo yemowudi eqhelekileyo.

Zininzi iindlela zokucinezela ingxolo yendlela eqhelekileyo. Ukongeza ekunciphiseni ingxolo yendlela eqhelekileyo evela kumthombo, eyona ndlela ixhaphakileyo yokucinezela ingxolo yendlela eqhelekileyo kukusebenzisa ii-inductors zemowudi eqhelekileyo ukuhluza ingxolo yendlela eqhelekileyo, oko kukuthi, ukuvala ingxolo yendlela eqhelekileyo esuka kwithagethi. isiphaluka. . Oko kukuthi, isixhobo sokuminxeka esiqhelekileyo sidityaniswe kuthotho kumgca. Injongo yale nto kukunyusa i-impedance ye-common-mode loop ukwenzela ukuba i-common-mode current ichithwa kwaye ivalwe (ibonakaliswe) yi-coke, ngaloo ndlela icinezela ingxolo yendlela eqhelekileyo kumgca.

 
Imigaqo yeNdlela eQhelekileyo yokuchoks okanye i-Inductors

Ukuba ipere yeekhoyili kwicala elifanayo linxeba kwindandatho yamagnetic eyenziwe yinto ethile yamagnetic, xa i-alternating current idlula, i-flux magnetic yenziwa kwiikhoyili ngenxa yokungeniswa kwe-electromagnetic. Kwimiqondiso yemowudi yokwahlula, iifluxes ezivelisiweyo zemagnethi zinobukhulu obufanayo kwaye zichasene kwicala, kwaye ziyacima enye kwenye, ngoko ke indlela yokwahlula-hlula eveliswa ngumsesane wemagnethi incinci kakhulu; ngelixa imiqondiso yemowudi eqhelekileyo, ubukhulu kunye nolwalathiso lwee-fluxes eziveliswayo zemagneti ziyafana, kwaye ezi zimbini zibekwe phezulu kwenye. Umsesane wamagnetic unendlela enkulu yokuthintela. Eli nqaku lenza i-inductor yemowudi eqhelekileyo inempembelelo encinci kwisignali yemowudi yokwahlula kwaye inomsebenzi olungileyo wokucoca ingxolo yemowudi eqhelekileyo.
(1) Indlela yokwahlula yangoku idlula kwikhoyili yemowudi eqhelekileyo, isalathiso semigca yemagnethi ichasene, kwaye indawo enemagnethi eyenziwe buthathaka. Inokubonwa ukusuka kwicala lemigca yamagnetic kulo mzobo ulandelayo - utolo oluqinileyo lubonisa isalathiso sangoku, kwaye umgca onamachaphaza ubonisa ulwalathiso lwentsimi yamagnetic.

(2) Imowudi eqhelekileyo yangoku idlula kwikhoyili yemowudi eqhelekileyo, isalathiso semigca yemagnethi iyafana, kwaye intsimi yamagnetic eyomeleziweyo iqiniswa. Inokubonwa ukusuka kwicala lemigca yamagnetic kumfanekiso olandelayo - utolo oluqinileyo lubonisa isalathiso sangoku, kwaye umgca onamachaphaza ubonisa indlela yombane.

I-inductance yekhoyili yemowudi eqhelekileyo ikwabizwa ngokuba yi-self-inductance coefficient. Siyazi ukuba i-inductance kukukwazi ukuvelisa intsimi yamagnetic. Kwi-coil yendlela eqhelekileyo okanye i-inductance ye-common mode, xa imowudi eqhelekileyo yangoku ihamba nge-coil, ekubeni isalathiso semigca yamagnetic iyafana, ukuvuza ukuvuza akuqwalaselwa. Kwimeko ye-, i-magnetic flux ibekwe phezulu, kwaye umgaqo-siseko uhambelana. Imigca yamandla kazibuthe eveliswa yikhoyili ebomvu kumzobo ongezantsi idlula kwikhoyili eluhlaza okwesibhakabhaka, kwaye imigca yemagnethi eveliswa yicoil eluhlaza nayo idlula kwikhoyili ebomvu kwaye ikhuthazane.

Ukususela kumbono we-inductance, i-inductance iphinda iphindwe kabini, kwaye i-flux linkage imele i-total magnetic flux. Kwi-inductors yemowudi eqhelekileyo, xa i-flux magnetic iphindwe kabini kwi-original, inani lokujika alitshintshi, kwaye langoku alitshintshi, ngoko kuthetha ukuba Njengoko i-inductance inyuswa ngamaxesha angama-2, ithetha ukuba ukulingana kwamagnetic permeability. iphindwe kabini.

Kutheni le nto imagnethi elinganayo ingena iphindwe kabini? Ukusuka kule fomula ilandelayo ye-inductance, kuba inani lokujika N alitshintshi, isekethe yamagnetic kunye nommandla onqamlezayo we-magnetic core imiselwa bubungakanani bomzimba we-core magnetic, ngoko ayitshintshi, kuphela. into yimagnetic permeability. u uphindwe kabini, ngoko ke ukuguquguquka kwamagnetic kunokuveliswa

Ke ngoko, xa imowudi eqhelekileyo yangoku idlula, i-inductance yemowudi eqhelekileyo isebenza kwimowudi ye-mutual inductance. Ngaphantsi kwesenzo se-inductance yokubambisana, i-inductance elinganayo inyuswe ngeendleko, ngoko i-inductance yendlela eqhelekileyo iya kuphinda iphindwe kabini, ngoko ibe nefuthe elihle kwisignali yendlela eqhelekileyo. Umphumo wokucoca ukuthintela isignali yemowudi eqhelekileyo kunye ne-impedance enkulu kwaye uyithintele ukuba idlule kwi-inductor yemodi eqhelekileyo, oko kukuthi, ukukhusela isignali ukuba idluliselwe kwinqanaba elilandelayo lesekethe. Oku kulandelayo yi-inductive reactance ZL eyenziwa yi-inductor.

Ukuqonda i-inductance ye-inductors yemowudi eqhelekileyo kwimo yemowudi eqhelekileyo, eyona nto iphambili kukuqonda inductance efanayo, onke amacandelo omagnetic, nokuba yintoni na igama, okoko nje ubamba ifom yotshintsho yemagnethi kwaye ubone ubume bemagnethi. intsimi yamagnetic itshintsha nge-phenomenon, kuya kuba lula ukuyiqonda, kwaye ke kufuneka sisoloko sibamba umgca wemagnethi, eyona ndlela i-intuitive yokuqonda kwethu intsimi yamagnetic. Khawucinge ukuba kungakhathaliseki ukuba ingcamango yegama elifanayo okanye igama elihlukeneyo okanye i-inductance mutual okanye i-magnetic field phenomenon, sihlala sidonsa umgca wemagnethi ukuze sibazi - inkosi "intonga yamagnetic" echazwe ngaphambili. Indlela yokuphelisa".
