ʻO ke ʻano maʻamau i kēia manawa: ʻelua mau hōʻailona (a i ʻole ka leo) me ka nui like a me ke kuhikuhi ma nā laina hōʻailona ʻokoʻa. Ma ke kaapuni.Ma ke ano nui, ua hooili ia ka leo o ka honua ma ke ano o ke ano o keia manawa, no laila, ua kapa ia no hoi ke ano leo ma'amau.
Nui nā ala e hoʻopau ai i ka walaʻau maʻamau. Ma waho aʻe o ka hōʻemi ʻana i ka walaʻau maʻamau mai ke kumu, ʻo ke ala maʻamau i hoʻohana ʻia no ka hoʻopau ʻana i ka walaʻau ʻano maʻamau ʻo ia ka hoʻohana ʻana i nā inductors mode maʻamau e kānana i ka walaʻau ʻano maʻamau, ʻo ia hoʻi, e ālai i ka walaʻau ʻano maʻamau mai ka pahu hopu. kaapuni. . ʻO ia hoʻi, ua hoʻopili ʻia kahi hāmeʻa choke mode maʻamau i ka laina ma ka laina. ʻO ke kumu o kēia, ʻo ia ka hoʻonui ʻana i ka impedance o ka loop mode maʻamau i hoʻopau ʻia a hoʻopaʻa ʻia ke ʻano o ke ʻano maʻamau (hōʻike ʻia) e ka choke, a laila e kāohi ai i ka walaʻau maʻamau i ka laina.
Nā Kuʻuna o nā ʻAha Kūʻai maʻamau a i ʻole nā Inductors
Inā e ʻeha ʻia kekahi mau wili ma ka ʻaoʻao hoʻokahi ma ke apo magnetic i hana ʻia me kekahi mea magnetic, i ka wā e hele ai kahi au i loko, ua hoʻokumu ʻia kahi flux magnetic i loko o nā coils ma muli o ka induction electromagnetic. No nā hōʻailona o ke ʻano ʻokoʻa, ua like ka nui a me ke kūʻē ʻana o nā ʻōhua magnetic i hana ʻia, a hoʻopau lākou i kekahi i kekahi, no laila, liʻiliʻi loa ka impedance mode differential i hana ʻia e ke apo magnetic; ʻoiai no nā hōʻailona maʻamau, ʻo ka nui a me ke kuhikuhi ʻana o nā fluxes magnetic i hana ʻia, ua like ia, a ua kau ʻia nā mea ʻelua ma luna o kekahi. Loaʻa i ke apo magnetic kahi impedance mode maʻamau. ʻO kēia hiʻohiʻona e hoʻemi iki i ka inductor mode maʻamau i ka hōʻailona mode differential a loaʻa iā ia ka hana kānana maikaʻi no ka walaʻau ʻano maʻamau.
(1) Ke hele nei ke ʻano ʻokoʻa i kēia manawa ma ke ʻano coil maʻamau, ʻo ke kuhikuhi ʻana o nā laina kahua magnetic e kū'ē ana, a ua nāwaliwali ke kahua magnetic. Hiki ke ʻike ʻia mai ka ʻaoʻao o nā laina mākēneki ma kēia kiʻi - ʻo ka pua paʻa e hōʻike ana i ke ala o ke au, a ʻo ka laina kikoʻī e hōʻike i ke kuhikuhi o ka māla magnetic.
(2) Ke hele nei ke ʻano hana maʻamau i ka coil mode maʻamau, ua like ke kuhikuhi o nā laina mākēneki, a ua hoʻoikaika ʻia ke kahua magnetic. Hiki ke ʻike ʻia mai ka ʻaoʻao o nā laina mākēneki ma kēia kiʻi - ʻo ka pua paʻa e hōʻike ana i ke ala o ke au, a ʻo ka laina kikoʻī e hōʻike i ke kuhikuhi o ka māla magnetic.
ʻO ka inductance o ka coil mode maʻamau i ʻike ʻia ʻo ia ka coefficient self-inductance. ʻIke mākou ʻo ka inductance ka hiki ke hana i kahi māla magnetic. No ka coil mode maʻamau a i ʻole inductance mode maʻamau, i ka wā e kahe ai ke ʻano maʻamau o kēia manawa ma o ka coil, no ka mea ua like ke kuhikuhi o nā laina magnetic, ʻaʻole i manaʻo ʻia ka leakage inductance. I ka hihia o , ua hoʻokuʻu ʻia ka flux magnetic, a ʻo ke kumu o ka inductance. ʻO nā laina kaha magnetic i hana ʻia e ka ʻōwili ʻulaʻula ma ke kiʻi ma lalo nei e hele i loko o ka wili polū, a ʻo nā laina kahua magnetic i hana ʻia e ka wili polū e hele pū i ka ʻōwili ʻulaʻula a hoʻoulu kekahi i kekahi.
Mai ka hiʻohiʻona o ka inductance, ua pāpālua ʻia ka inductance, a ʻo ka loulou flux e hōʻike ana i ka huina magnetic flux. No nā inductors mode maʻamau, i ka wā ʻelua o ka hoʻololi ʻana o ka magnetic i ka mua, ʻaʻole loli ka helu o nā huli, a ʻaʻole hoʻololi ke ʻano o kēia manawa, a laila ʻo ia hoʻi ʻo ka hoʻonui ʻia ʻana o ka inductance e 2 mau manawa, ʻo ia hoʻi, ʻo ia ka mea like. pāpālua.
No ke aha i pāpālua ʻia ai ka like me ka permeability magnetic? Mai kēia ʻano inductance, ʻoiai ʻaʻole e loli ka helu o nā huli N, ʻo ke kaapuni magnetic a me ka ʻāpana cross-sectional o ka magnetic core e hoʻoholo ʻia e ka nui kino o ka magnetic core, no laila ʻaʻole ia e loli, ʻo ia wale nō. ʻO ka mea ka magnetic permeability. Ua pāpālua ʻia ʻoe, no laila hiki ke hoʻonui ʻia ka flux magnetic
No laila, i ka wā e hele ai ke ʻano maʻamau i kēia manawa, e hana ka inductance mode maʻamau i ke ʻano inductance. Ma lalo o ka hana o ka inductance like, hoʻonui ʻia ka inductance e like me ke kumukūʻai, no laila e pālua ʻia ka inductance mode maʻamau, no laila he hopena maikaʻi i ka hōʻailona maʻamau. ʻO ka hopena kānana ke kāohi i ka hōʻailona mode maʻamau me kahi impedance nui a pale iā ia mai ka hele ʻana i ka inductor mode maʻamau, ʻo ia hoʻi, e pale i ka hōʻailona mai ka lawe ʻia ʻana i ka pae aʻe o ke kaapuni. ʻO ka mea aʻe ka inductive reactance ZL i hana ʻia e ka inductor.
No ka hoʻomaopopo ʻana i ka inductance o nā inductors mode maʻamau i ke ʻano mode maʻamau, ʻo ka clue nui ka hoʻomaopopo ʻana i ka inductance like, nā ʻāpana magnetic āpau, ʻaʻohe mea o ka inoa, ʻoiai ʻoe e hopu i ke ʻano hoʻololi o ke kahua magnetic a ʻike i ke ʻano o ka hoʻololi ʻana o ke kahua magnetic ma o ka hanana, e maʻalahi ka hoʻomaopopo ʻana, a laila pono mākou e hopu mau i ka laina kahua magnetic, ʻo ia ke ʻano intuitive o ko mākou ʻike ʻana i ka māla magnetic. E noʻonoʻo ʻoe ʻaʻohe manaʻo o ka inoa like a i ʻole ka inoa ʻokoʻa a i ʻole ka inductance like ʻole a i ʻole ke ʻano o ke kahua magnetic, e huki mau mākou i ka laina kahua magnetic e ʻike iā lākou - haku i ka "magnetic rod" i wehewehe mua ʻia. ʻO ke ʻano o ka makani”.
