E aʻo i ka nui inductance o ka inductance ʻano maʻamau . E hāhai i ka mea hana inductance (ʻoihana hoʻolako ʻia: iho inductor, nā kahahānai inductor) e aʻo:
ʻO ke ʻano ʻokoʻa ʻokoʻa: He mau hōʻailona o ka nui like a me ka ʻaoʻao ʻē aʻe i kahi mau laina hōʻailona ʻokoʻa, hoʻohana mau ʻia i kahi kaapuni
ʻO ke au, no kahi laina hōʻailona, ʻo ia ke kahe ma waena o ka laina hōʻailona a me ka pae hōʻailona.
ʻAno maʻamau maʻamau: He mau hōʻailona (a i ʻole he mau leo) o ka like a me ke kuhikuhi ma kahi o nā laina hōʻailona ʻokoʻa. Ma ke kaapuni,
ʻO ka maʻamau, lawe ʻia ka walaʻau papa e ka mode mode maʻamau, no laila ua kapa ʻia kēia ʻano o ka walaʻau maʻamau.
Nui a hewahewa nā ala e kāohi ai i ka walaʻau maʻamau. Ma waho aʻe o ka hōʻemi ʻana i ka walaʻau maʻamau i ke kumu, hoʻohana pinepine ʻia ka inductance maʻamau e kānana i ka walaʻau maʻamau, ʻo ia hoʻi, e ālai i ka walaʻau maʻamau i waho o ke kaapuni pahuhopu. kaapuni. ʻO ka pahuhopu e hoʻonui i ka impedance o ka pōʻaiapuni maʻamau i hoʻopau ʻia a kāohi ʻia ke ʻano maʻamau i ke ʻano o ka choke, a pēlā e kaomi ai i ka walaʻau maʻamau i ke kaapuni.
ʻO ke kumu o ka choke maʻamau a i ʻole inductor
Inā ʻeha nā ʻōwili ʻelua i ke ala like ma ke apo mākēneki o kekahi mea ʻume mākenēki, hana ʻia ka flux manō i loko o ka ʻōwili ma muli o ke komo ʻana o ka electromagnetic i ka wā e hele ai kahi au i waena o ka wili. No nā ʻōnaehana ʻano ʻokoʻa, ka flux magnet i hoʻokumu ʻia e ua like ka nui o ke apo magnet ma ka nui a me ka ʻaoʻao ʻē aʻe, a hoʻopau nā mea ʻelua i kekahi, no laila, ua liʻiliʻi loa ka impedance mode i hana ʻia e ke apo magnet. No nā ʻōuli maʻamau, ua like ka nui o ka hoʻoiho magnet. a me ke kuhikuhi, a ua hoʻopili ʻia nā mea ʻelua ma luna o kekahi me kekahi e hana i kahi impedance ʻano nui o ke apo magnet. ʻO kēia ʻano hana e hoʻoliʻiliʻi ka mana o ka inductance mode maʻamau i ka hōʻailona mode ʻokoʻa a ʻoi aku ka maikaʻi o ka kānana ʻana i ka hana i ka walaʻau maʻamau.
(1) Ke hele nei ke ʻano ʻano ʻokoʻa ma waena o ka coil mode-maʻamau, aia ka laina kahua magnet i kahi ʻaoʻao ʻē a hoʻonāwaliwali ʻia ka mākia magnet i hoʻokomo ʻia. Hiki ke ʻike ʻia mai ke kuhikuhi o ka laina kahua mākēneki i ke kiʻi ma lalo aʻe o ka ʻūlū laina paʻa i ke kuhi o ke au a ʻo ka laina kaha i kū i ka ʻaoʻao o ka pā magnet.
(2) Ke hele nei ka mode-mode ma waena o ka coil mode-maʻamau, a ua hoʻokūpaʻa ʻia ka māla magnetika ma muli o ke kuhikuhi like o ka laina kahua magnet. Hiki ke ʻike ʻia mai ke kuhikuhi o ka laina kahua mākēneki i ke kiʻi ma lalo aʻe o ka ʻūlū laina paʻa i ke kuhi o ke au a ʻo ka laina kaha i kū i ka ʻaoʻao o ka pā magnet.
Hoʻohui ʻano maʻamau o ka ʻōwili a i kapa ʻia paha coefficient hoʻokomo ponoʻī, ʻike mākou i ka inductance e hana i ka hiki o ka māla magnet, ke ʻano maʻamau a i ʻole ka mode inductor coil maʻamau, ke kahe ka maʻamau maʻamau i waena o kahi wili, ma muli o nā laina kahua uila ma ka ʻaoʻao like, me ka ʻole o ka noʻonoʻo ʻana ma lalo o ke ʻano o ka leakage inductance, magnet flux, ʻo kāna kumu he inductance ʻelua, ma lalo o nā laina māpuna uila coil coil ma o ka laina polū, ʻulaʻula a uliuli hoʻi ma o ka. ʻōwili ʻulaʻula, hoʻokomo
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.
Pehea e pāpālua ai ka permeability like? Mai ke kumumanaʻo inductance e hiki mai ana, ʻoiai ʻaʻole e loli ka helu o nā huli N, ua hoʻoholo ʻia ke kaapuni uila a me ka ʻāpana ʻāpana o ka ʻume mākeneka e ka nui o ke kino o ka mea nui, no laila ʻaʻohe loli. ʻO ke kumu wale nō ka pālua ʻana o ka permeability U, no laila hiki ke hoʻonui ʻia ka flx magnet
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.
