Aʻo le inductance aofaʻi o masani-faiga inductance . Mulimuli i le inductance gaosi oloa (faʻapitoa sapalaiina: inductor axial, Oloa vevela inductor radial) e aʻoaʻo ai:
Eseesega taimi nei: O se pea o faʻailoga o le tutusa tele ma faʻafeagai itu i luga o se pea o faʻailoga laina eseʻese, masani ona faʻaaogaina i totonu o se matagaluega
O le taimi nei, mo se laina faʻailo, o le taimi nei o loʻo tafe i le va o le laina faʻailoga ma le eleele faʻailoga.
Masani faiga nei: O se pea o faʻailo (poʻo leo) o le tutusa tele ma le faʻasinoga i luga o se pea o eseesega laina faʻailo. I le matagaluega,
O le mea e masani ai, o le pisapisao o le eleele e faʻasalalauina e le tulaga masani masani, o lea e taʻua ai foʻi o le leo masani.
E tele auala e taofi ai le masani-auala leo. I le faʻaopopoina i le faʻaititia o leo-masani leo i puna, masani masani inductance e masani ona faʻaaoga e faʻamama masani ai-ituaiga leo, o lona uiga, e poloka masani-auala leo i fafo atu o le faʻasologa taamilosaga. O lona uiga, o se masani auala fetinaʻi i le faasologa i totonu o le O le faʻamoemoe o le faʻateleina o le faʻafitauli o le taamilosaga masani ina ia faʻaumatia ma poloka (atagia mai) e le taimi nei le masani masani, ma tineia ai le pisapisao masani i totonu o le matagaluega.
O le faʻavae o le masani-auala fetinaʻi poʻo inductor
Afai o se pea coil ua manua i le itu lava e tasi i luga o le maneta mama o nisi maneta mea, maneta flux e tupu i totonu o le coil ona o le eletise electromagnetic pe a pasi se isi taimi nei pasi i totonu o le coil. Mo eseesega auala faʻailoga, le maneta fluks fausiaina e o le mama maneta e tutusa i le tele ma faafeagai i le itu, ma le lua faaleaogaina tasi le tasi i fafo, o lea le eseesega auala impedance faatupuina e le maneta mama e matua laitiiti lava. Mo masani-auala faailo, o le maneta fesuiaiga faia o le tutusa tutusa ma le taʻiala, ma o le lua o loʻo faʻapipiʻiina i luga o le tasi ma le isi e maua ai le tele masani-auala impedance o le maneta mama. O lenei uiga faia le masani auala inductance e faʻaitiitia ai le aʻafiaga i luga o le eseesega auala faʻailoga ma e sili lelei le faʻamamaina gaioiga i le masani auala leo.
(1) Pe a pasia le eseesega auala nei i totonu o le masani-mode coil, o le maneta laina laina o loʻo i le isi itu ma o le faʻamalosia fanua maneta ua faʻavaivaia. E mafai ona vaʻaia mai le itu o laina laina maneta i le ata o loʻo i lalo, o le uʻamea o le laina maʻa e fai ma sui o le taimi nei ma le laina gagase e faʻasino i le itu o le fanua maneta
(2) O le masani-auala taimi nei pasi atu i le masani-mode coil, ma o le maneta fanua ua faʻamalosia ona o le tutusa itu o le laina laina maneta. E mafai ona vaʻaia mai le itu o laina laina maneta i le ata o loʻo i lalo, o le uʻamea o le laina maʻa e fai ma sui o le taimi nei ma le laina gagase e faʻasino i le itu o le fanua maneta
Masani-faiga inductance o coil pe taʻua o oe lava-induction coefficient, matou te iloa o le inductance e maua ai le gafatia o le maneta fanua, o le masani auala poʻo masani-auala inductor coil, pe a o le masani-auala taimi nei tafe i totonu o se uila, ona o le laina malae maneta i le itu lava e tasi, aunoa ma le amanaʻia i lalo o le tuutuuga o le leakage inductance, maneta flux, o lona faʻavae o le faʻatasi inductance, lalo coil coil maneta laina fanua e ala i le lanumoana, mumu ma lanumoana coil maneta laina fanua e ala foʻi i le coil mumu, faʻatumuina tasi i le tasi.
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.
Faʻafefea mafai faʻaluaina permeability tutusa? Mai le mulimuli inductance fuafaatatau, talu ai le aofai o liliu N e le suia, o le maneta matagaluega ma le koluse-vaega vaega o le maneta autu ua fuafuaina e le faaletino tele o le maneta autu, o lea e leai se suiga. Pau lava le mafuaʻaga o le permeability U e faʻaluaina, o lea e mafai ai ona faʻateleina le fesuiaʻiga o maneta
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.
