Funda inani lokungeniswa kwe-inductance ejwayelekile yemodi . Landela umkhiqizi we-inductance (okunikezwe ngobuchwepheshe: i- inductor Axial, i- inductor osabalalayo) ukuze ufunde:
Imodi yokuhlukahluka kwamanje: Izimpawu ezimbili zosayizi ofanayo nokuqondiswa okuphambene kulayini wolayini abahlukene, ovame ukusetshenziselwa isifunda
Okwamanje, kolayini wesiginali, ukugeleza kwamanje phakathi kolayini wesiginali nomhlabathi wesiginali.
Imodi ejwayelekile yamanje: Isiginali yamasiginali (noma imisindo) yobukhulu obufanayo nesiqondisi kumugqa wolayini wokuhlukanisa.
Ngokuvamile, umsindo womhlabathi udluliswa yimodi ejwayelekile yamanje, ngakho-ke ubizwa nangokuthi imodi ejwayelekile yomsindo.
Kunezindlela eziningi zokucindezela umsindo wemodi ejwayelekile. Ngokungeziwe ekunciphiseni umsindo wemodi ejwayelekile emthonjeni, imodi ejwayelekile ye-inductance ivame ukusetshenziselwa ukuhlunga umsindo wemodi ejwayelekile, okungukuthi, ukuvimba umsindo wemodi ejwayelekile ngaphandle kwesekethi eqondisiwe. Inhloso ukukhulisa ukuvinjelwa kwesifunda semodi ejwayelekile ukuze i-current-mode yamanje idliwe futhi ivinjwe (ivezwe) ukuminyaniswa, ngaleyo ndlela icindezele umsindo wemodi ejwayelekile esifundeni.
Umgomo wokuminyanisa imodi ejwayelekile noma i-inductor
Uma amakhoyili amabili elinyazwa ohlangothini olufanayo kwindandatho kazibuthe yento ethile kazibuthe, amandla kazibuthe akhiqizwa kwikhoyili ngenxa yokungeniswa kwamandla kagesi lapho amandla ashintshanayo edlula kwekhoyili. iringi kazibuthe iyalingana ngosayizi ohlukile, futhi bobabili bayakhanselana, ngakho-ke impedance yemodi ehlukile eyenziwe iringi kazibuthe incane kakhulu.Ngokwesiginali yemodi ejwayelekile, amandla kazibuthe akhiqizwayo anobukhulu obufanayo ukuqondiswa, futhi lezi zibili zibekwe phezu komunye nomunye ukukhiqiza impedance enkulu ejwayelekile yemodi yamagnetic ring.Lesi sici senza ukwehliswa kwemodi ejwayelekile kube nethonya elincane kusiginali yemodi ehlukile futhi kunokusefa okungcono kunomsindo wemodi ejwayelekile.
(1) Lapho imodi yokuhlukahluka idlula kwekhoyili yemodi ejwayelekile, ulayini kazibuthe uqonde kolunye uhlangothi futhi amandla kazibuthe abangelwa ayenziwa buthakathaka. Kungabonakala kusuka ekuqondeni komugqa wensimu kazibuthe kusibalo esingezansi ukuthi umcibisholo womugqa oqinile umele ukuqondiswa komugqa wamanje futhi umugqa odonswe umele inkomba yensimu kazibuthe
(2) Okwamanje imodi ejwayelekile idlula kwikhoyili yemodi ejwayelekile, futhi amandla kazibuthe ayaqiniswa ngenxa yesiqondiso esifanayo sentambo kazibuthe. Kungabonakala kusuka ekuqondeni komugqa wensimu kazibuthe kusibalo esingezansi ukuthi umcibisholo womugqa oqinile umele ukuqondiswa komugqa wamanje futhi umugqa odonswe umele inkomba yensimu kazibuthe
Ukwehliswa kwemodi ejwayelekile kwekhoyili noma okubizwa ngokuthi yi-self-induction coefficient, siyazi ukuthi i-inductance ikhiqiza amandla kazibuthe, imodi ejwayelekile noma ikhoyili ye-inductor ejwayelekile, lapho imodi ejwayelekile yemodi igeleza ngekhoyili, ngenxa ulayini kazibuthe ohlangothini olufanayo, ngaphandle kokucatshangelwa ngaphansi kwesimo sokungenzi kahle kokuvuza, ukugeleza kukazibuthe, umgomo wayo ukungahambisani, ngaphansi kwemigqa yekhoyili kazibuthe kazibuthe ngokusebenzisa imigqa yensimbi kazibuthe ehlaza okwesibhakabhaka, ebomvu noluhlaza okwesibhakabhaka futhi ngokusebenzisa ikhoyili ebomvu, ukufakwa komunye nomunye.
From the point of view of inductance, inductance is multiplied, magnetic chain represents the total magnetic flux, the common-mode inductor, when magnetic flux is doubled, circle number has not changed, the current didn't also did not change, so mean increased inductance for 2 times, means that the equivalent permeability into 2 times.
Ngabe ukuphindaphindwa okulinganayo kungaphindwa kanjani? Kusuka kwifomula yokungenisa elandelayo, njengoba inani lamaphuzu N engashintshi, isekethe kazibuthe nendawo enqamulelayo yomgogodla kunqunywa ngosayizi womzimba wensimbi kazibuthe, ngakho-ke alukho ushintsho. Isizathu kuphela ukuthi ukungena kwe-U kuphindwe kabili, ngakho-ke amandla amaningi kazibuthe angenziwa
Common-mode inductor in common mode, therefore, when an electric current passes through, work under the mutual inductance model, under the effect of mutual inductance, the equivalent inductance is cost increase, therefore common mode impedance will be multiplied, and the common mode signal has good filtering effect, also is the common mode signal with large impedance block, don't let it pass the common-mode inductor, also is not to let this signal transmission to the next level of the circuit, the following is the inductive reactance ZL.
Know common-mode inductor under the mode of common mode inductance, is the main clue to know mutual inductance, magnetic components of all, no matter what name as long as mastering the form of the change of the magnetic field, magnetic field changes through the phenomenon to essence, also easy to understand, moreover we always grasp the magnetic field lines, it is our understanding the visual form of the magnetic field, consider whether the same side or different name or concept of the mutual inductance phenomenon or magnetic field, we are drawing the lines of magnetic force to realize their - master "magnet winding method" is explained before.
