Funda inani lokungeniswa kwendlela eqhelekileyo yokunyanzeliswa . Landela umenzi we-inductance (obonelelwe ngobuchule: i- inductor yezihlunu, i- inductor ziqu) ukuze ufunde:
Imowudi yomahluko okhoyo ngoku: Izibini ezibonisa ubungakanani obufanayo kunye nolwalathiso olwahlukileyo kwimigca yokwahlula imiqondiso, edla ngokusetyenziswa kwisekethe
Okwangoku, kumgca wesiginali, kukuhamba ngoku phakathi komgca wesiginali kunye nomhlaba womqondiso.
Imodi eqhelekileyo yangoku: Izibini zemiqondiso (okanye imisindo) yobukhulu obufanayo kunye nolwalathiso kwimigca yesiginali esahlukileyo.
Ngokubanzi, ingxolo yomhlaba idluliswa yimowudi eqhelekileyo yangoku, ke ikwabizwa ngokuba yingxolo yendlela eqhelekileyo.
Zininzi iindlela zokucinezela ingxolo yendlela eqhelekileyo. Ukongeza ekunciphiseni ingxolo yendlela eqhelekileyo emthonjeni, ukunganyanzeliswa kwendlela eqhelekileyo kuhlala kusetyenziswa ukucoca ingxolo yendlela eqhelekileyo, oko kukuthi, ukuvala ingxolo yemowudi eqhelekileyo kwisekethe ekujoliswe kuyo, oko kukuthi, indlela eqhelekileyo yokutswina kuthotho lweethotho. Injongo kukunyusa ukunganyanzeleki kwendlela ejikelezayo ukuze imo eqhelekileyo igqitywe kwaye ivalwe (ibonakaliswe) kukukrwitshwa, ngaloo ndlela kucinezelwa ingxolo yendlela eqhelekileyo kwisekethe.
Umgaqo wendlela eqhelekileyo yokutswina okanye i-inductor
Ukuba isibini sekhoyili sonzakele kwicala elinye kwisangqa semagnethi yento ethile yemagnethi, umbane wombane uveliswa kwikhoyili ngenxa yokungeniswa kombane xa kutshintshana enye ngoku kwiikhoyili. Isangqa semagnethi siyalingana ngobukhulu kwaye sijolise kwicala, kwaye ezi zimbini ziyarhoxa ngaphandle, ke umahluko kwimowudi yendlela eyenziwe yiringi yamagnetic incinci kakhulu.Ngokuba imiqondiso yendlela eqhelekileyo, ukuhamba kwemagnethi okwenziwe ngobukhulu obufanayo Isalathiso senza ukuba ukunganyanzeleki kwendlela eqhelekileyo kube nefuthe elincinci kumqondiso wemowudi eyahlukileyo kwaye kunendlela yokusebenza yokuhluza kwimodi yendlela eqhelekileyo.
(1) Xa imo yolwahluko okhoyo ngoku idlula kwi-coil yendlela eqhelekileyo, umgca wemagnethi yomhlaba ujongene nendlela eyahlukileyo kwaye amandla e-magnetic ayenziwe buthathaka. Ingabonakala kwicala lomgca womhlaba wamagnetic kumfanekiso ongezantsi ukuba umgca oqinileyo wecala umela ulwalathiso lwangoku kunye nomgca odibeneyo umele ulwalathiso lwe-magnetic field
(2) Imowudi eqhelekileyo ekhoyo ngoku idlula kwikhoyili yemowudi eqhelekileyo, kwaye umhlaba womazibuthe uyomelezwa ngenxa yendlela efanayo yomgca wemagnethi yomhlaba. Ingabonakala kwicala lomgca womhlaba wamagnetic kumfanekiso ongezantsi ukuba umgca oqinileyo wecala umela ulwalathiso lwangoku kunye nomgca odibeneyo umele ulwalathiso lwe-magnetic field
Imowudi eqhelekileyo yekhoyili okanye ebizwa ngokuba yi-coefficient yokuzenzela, siyazi ukuba i-inductance ivelisa amandla e-magnetic field, imo eqhelekileyo okanye i-coil ye-inductor coil, xa i-mode-mode yangoku ihamba ngekhoyili, ngenxa imigca yemagnethi yomhlaba kwicala elinye, ngaphandle kokuthathela ingqalelo phantsi kokuphamba kokuvuza, ukuhamba ngamandla kwemagnethi, umgaqo wayo kukuhambelana, ngaphantsi kwekhoyili coil imigca yemagnethi ngombala oluhlaza okwesibhakabhaka, obomvu kunye nohlaza okwesibhakabhaka. ebomvu coil, induction omnye komnye.
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.
Ngaba ukuphindaphindeka okulinganayo kunokuphindwaphindwa? Ukusuka kule fomyula ilandelayo ye-inductance, kuba inani lokujika kwe-N alitshintshi, isekethe yamagnetic kunye nendawo enqamlezileyo yesiseko semagneti imiselwe bubungakanani bomzimba wombindi wemagneti, ke akukho lutshintsho. Esona sizathu kukuba u-U wokuphindaphindeka uphindaphindwe kabini, ngenxa yoko amandla amakhulu emagneti anokuveliswa
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.
