Introduction to Inductance

ʻO ka inductance kahi waiwai maʻamau o nā kaapuni uila e pili ana i ka hiki o kahi uwea e mālama i ka ikehu i loko o kahi māla magnetic ke hele ka ʻākuhi uila ma ka uea. ʻO nā mea hoʻokomo liʻiliʻi, e like me nā mea i loko o nā tausani o nā hāmeʻa uila, hoʻohana i kēia kumu no ka hoʻokele ʻana i kēia manawa a me ka kānana i nā hōʻailona. ʻO ka ikaika o ke kahua magnetic o inductor e pili ana i ke kahe o kēia manawa a me nā waiwai kino ʻē aʻe e like me ka helu o nā huli a me ke ʻano o ka mea kumu. Pono kēia ʻike kumu i loaʻa i nā inductors liʻiliʻi a me nā noi like ʻole i nā uila uila o kēia manawa.

Nā ʻano o nā mea hoʻokomo liʻiliʻi

ʻElua mau hiʻohiʻona i hiki ke hoʻokaʻawale ʻia nā inductors liʻiliʻi. ʻO ka mea kumu a me ka hoʻonohonoho ʻana, kēlā me kēia ʻano kūpono no nā noi kikoʻī e pili ana i ka hoʻomaʻamaʻa ʻana i ka mana a me ka hana hōʻailona. Hoʻohana mau ʻia nā inductors air-core, ferrite-core, a me toroidal. ʻAʻole i loaʻa i nā inductors ea-core ke kumu magnetic paʻa ka hopena i ka liʻiliʻi o ka inductance a me nā poho ʻoiai ma lalo o nā mana koʻikoʻi e kūpono iā lākou no ke alapine kiʻekiʻe. I kēia manawa, loaʻa i nā inductors ferrite-core nā hiʻohiʻona magnetic e ʻae i ka inductance ʻoi aku ka nui a hiki ke hoʻohana ʻia no ke kumu o ka hoʻopau ʻana i ka walaʻau a me ka hoʻololi ʻana i ka mana. ʻO Toroidal inductor, donut shaped, ʻaʻohe ea ea, hiki ke hana i ka inductor e hana i ke kahua magnetic inconsistent a no laila hiki ke haʻahaʻa haʻahaʻa a hana i ka walaʻau EMI, kūpono no nā kaʻa lako mana.

Nā ʻano o nā mea hoʻokomo liʻiliʻi

Hōʻike ʻia nā inductors liʻiliʻi e kekahi mau ʻāpana koʻikoʻi, ʻo ia hoʻi: inductance, helu ʻia i kēia manawa, kūpaʻa a me ke kumu maikaʻi. Hōʻike ʻia ka inductor mālama e kona inductance, maʻamau ma Henries (H). ʻO ke au i helu ʻia ʻo ia ke ʻano kiʻekiʻe loa e hiki i ka inductor ke hana me ka ʻole o ka hoʻopiha ʻana a i ʻole ka wela. Hoʻopili ʻia ka nalowale o ka mana i ka inductor e ke kūpaʻa, a ʻoi aku ka maikaʻi o ke kūʻē liʻiliʻi i mea e loaʻa ai ka hana kiʻekiʻe. A ʻo ka hopena, ʻoi aku ka kiʻekiʻe o ka waiwai o Q (qualify factor), ʻoi aku ka maikaʻi o ka hale kūʻai inductor a hoʻokuʻu i ka ikehu (e liʻiliʻi i ka pau ʻana o ka ikehu e like me ka wela). He mea nui ka ʻike maikaʻi i kēia mau mea no nā mea ʻenekinia a me nā mea leʻaleʻa uila i ke koho ʻana i nā inductors no kā lākou hoʻolālā, a hōʻoia i ko lākou kūlike me ka hoʻokolohua / prototype a e hōʻoia i ka hoʻokō ʻana i kā lākou hana.

Nā mea e noʻonoʻo ai

I ka hiki ʻana mai i ke koho ʻana i ka inductor liʻiliʻi maikaʻi loa no kāu papahana, aia kekahi mau manaʻo nui i ka pāʻani. ʻO ka mea koʻikoʻi koʻikoʻi ka inductance, ʻo ia hoʻi ka waiwai e hiki ai i kahi inductor ke mālama i ka ikehu. E hoʻokō kēia i nā pono o kāu kaapuni no kāna hana āpau. ʻO ka lua, ʻaʻole hiki ke poina i ka helu inductor i kēia manawa. ʻO ia ka mea kiʻekiʻe loa i hiki i ka inductor ke lawe me ka ʻole o kāna hana i hoʻohālikelike ʻia, a he mea nui ia no ka mālama ʻana i nā kūlana hana palekana a me ka pale ʻana i ke kaapuni mai ka pōʻino e ka overheating. ʻO ka mea hope loa, ʻo ka nui o ka inductor liʻiliʻi he mea koʻikoʻi nui, ʻoi aku ka nui o nā hoʻokō paʻa kahi i uku ʻia ai ka nui. ʻO ka paʻakikī ka loaʻa ʻana o kahi kaulike maikaʻi o kēia mau mea e like me ka loaʻa ʻana o kahi inductor e hoʻokō i nā koi uila a me ke kino no kāu papahana.

Hoʻopili i ka Inductor i ka noi

No ka hoʻoholo ʻana i ka inductor liʻiliʻi kūpono no kāu noi, ʻo ka ʻike i kāu mea e pono ai ka ʻāpana e hana ai he mea nui.

No ke kōkua ʻana i ke kaʻina koho, hāʻawi nā mea hana i nā ʻikepili nui e wehewehe ana i ka hana o kahi inductor ma lalo o nā kūlana like ʻole. Aia ma lalo kahi papa hōʻuluʻulu pōkole o kekahi mau noi maʻamau, a me kā lākou inductor pono:

Nā hewa maʻamau i ke koho ʻana

No ke koho ʻana i nā inductors liʻiliʻi, ʻo kahi ʻano i mālama ʻole ʻia ʻo ia ka hana pinepine. ʻAʻole ʻoi aku ka maikaʻi o kahi inductor maikaʻi no nā alapine haʻahaʻa i nā alapine kiʻekiʻe no ka mea e piʻi aʻe kona mau poho kū'ē, a haʻahaʻa paha kona permeability kumu. ʻO kahi lua hou aʻe ke nānā ʻole ʻia ke kumu maikaʻi (Q) o ka inductor Q e ana i ka hiki o ka inductor ke mālama a hoʻokuʻu i ka ikehu. Hiki i kēia kumu Q haʻahaʻa ke kumu i ka nalowale o ka ikehu, ʻoi aku ka nui o nā hana ma ke alapine kiʻekiʻe. Eia kekahi, inā e hoʻopili kino ʻia nā mea hoʻokomo liʻiliʻi a pau, ʻaʻole ia e nānā i ka nui kino o ka lumi i loaʻa ma ka papa kaapuni hiki ke koi i ka hoʻolālā hou ʻana a i ʻole nā ​​​​hoʻololi hana. E hoʻokaʻawale i kēia mau lua a hauʻoli i ka holomua maikaʻi ke koho ʻana i nā ʻāpana a me ka hoʻolālā ʻana i nā kaapuni.

Hoʻokō i nā Inductors Liʻiliʻi ma nā Kaapuni

Hoʻohui Kaapuni Kumu

Ke ʻimi nei i kahi luʻi hou? He mea koʻikoʻi kēia mau minuke no ka kānana ʻana, kahi mālama ikehu a no ka hana ʻana i nā māla magnetic. E hoʻomaka ana me ka hoʻohui kaapuni maʻamau, ʻo ka hana o ka inductor i loko o ke kaapuni he mea nui ia e hopu ai. No ka laʻana, ma ka ʻōnaehana lako mana, hiki i nā inductors liʻiliʻi ke kōkua i ka hoʻohaʻahaʻa ʻana i nā ripples voltage i mea e hoʻonui ai i ka puka uila paʻa holoʻokoʻa.
