I ka hiki ʻana i ka inductor, hopohopo nā mea hoʻolālā no ka mea ʻaʻole lākou ʻike pehea e hoʻohana aiinductor. I nā manawa he nui, e like me ka pōpoki a Schrodinger: aia wale nō ke wehe ʻoe i ka pahu, hiki iā ʻoe ke ʻike inā ua make ka pōpoki a ʻaʻole paha. I ka wā wale nō i hoʻopaʻa ʻia ai ka inductor a hoʻohana ʻia i ke kaapuni hiki iā mākou ke ʻike inā hoʻohana pololei ʻia a ʻaʻole paha.

No ke aha i paʻakikī loa ai ka inductor? No ka mea, pili ka inductance i ke kahua electromagnetic, a ʻo ke kumumanaʻo kūpono o ke kahua electromagnetic a me ka hoʻololi ʻana ma waena o nā māla magnetic a me ka uila ka mea paʻakikī loa e hoʻomaopopo. ʻAʻole mākou e kūkākūkā i ke kumu o ka inductance, ke kānāwai o Lenz, ke kānāwai lima ʻākau, a me nā mea ʻē aʻe, e pili ana i ka inductor, ʻo ka mea e pono ai mākou e hoʻolohe i nā ʻāpana kumu o ka inductor: inductance value, rate current, resonant frequency, quality factor. (Q waiwai).

Ma ke kamaʻilio e pili ana i ka waiwai inductance, maʻalahi ka hoʻomaopopo ʻana i nā mea āpau ʻo ka mea mua a mākou e hoʻolohe ai ʻo ia kona "waiwai inductance". ʻO ke kī ʻo ka hoʻomaopopo ʻana i ke ʻano o ka waiwai inductance. He aha ke ʻano o ka waiwai inductance? Hōʻike ka waiwai inductance i ka nui o ka waiwai, ʻoi aku ka ikaika o ka inductance hiki ke mālama.

A laila pono mākou e noʻonoʻo i ke kuleana o ka waiwai inductance nui a liʻiliʻi paha a me ka nui o ka ikehu e mālama ai. I ka wā e nui ai ka waiwai inductance, a i ka wā e liʻiliʻi ai ka waiwai inductance.

I ka manawa like, ma hope o ka hoʻomaopopo ʻana i ka manaʻo o ka inductance waiwai a me ka hui pū ʻana me ke ʻano kumu o ka inductance, hiki iā mākou ke hoʻomaopopo i ka mea e pili ana i ka waiwai o ka inductance i ka hana ʻana o ka inductor a pehea e hoʻonui ai a hoʻemi paha.

He mea maʻalahi loa ka helu o kēia manawa, e like me ke kū'ē ʻana, no ka mea ua pili ka inductor i ka moʻo i ke kaapuni, e kahe i kēia manawa. ʻO ka waiwai o kēia manawa i ʻae ʻia ʻo ia ka helu i koho ʻia.

ʻAʻole maʻalahi ka hoʻomaopopo ʻana i ke alapine resonant. ʻO ka inductor i hoʻohana ʻia i ka hoʻomaʻamaʻa ʻaʻole pono he mea kūpono. E loaʻa iā ia ka capacitance like, ke kūpaʻa like a me nā ʻāpana ʻē aʻe.

ʻO ke alapine Resonant ka mea ma lalo o kēia alapine, ʻo nā ʻano kino o ka inductor ke ʻano like me ka inductor, a ma luna o kēia alapine, ʻaʻole ia e hana e like me ka inductor.

ʻOi aku ka huikau o ke kumu maikaʻi (Q value). ʻO ka ʻoiaʻiʻo, ʻo ka mea maikaʻi e pili ana i ka ratio o ka ikehu i mālama ʻia e ka inductor i ka nalowale o ka ikehu i hana ʻia e ka inductor i loko o kahi pōʻai hōʻailona ma kahi alapine hōʻailona.

Pono e hoʻomaopopo ʻia ma ʻaneʻi e loaʻa ka mea maikaʻi ma kahi alapine. No laila, ke ʻōlelo mākou he kiʻekiʻe ka waiwai Q o kahi inductor, ʻo ia ka mea ʻoi aku ka kiʻekiʻe ma mua o ka waiwai Q o nā inductors ʻē aʻe ma kahi kikoʻī alapine a i ʻole kekahi ʻāpana alapine.

E hoʻomaopopo i kēia mau manaʻo a laila e hoʻohana iā lākou.

Hoʻokaʻawale ʻia nā Inductors i ʻekolu mau ʻāpana i ka noi: nā mana inductors, high-frequency inductors a me nā inductors maʻamau.

ʻO ka mua, e kamaʻilio kākoumea hoʻokomo mana.
Hoʻohana ʻia ka inductor mana i ke kaapuni mana. Ma waena o nā mana inductors, ʻo ka mea nui e hoʻolohe i ka waiwai inductance a me ka waiwai o kēia manawa. ʻAʻole pono e hopohopo nui ʻia ke alapine resonance a me ke kumu maikaʻi.

No ke aha?No ka meanā mea hoʻokomo manahoʻohana pinepine ʻia i nā kūlana haʻahaʻa a me nā kūlana kiʻekiʻe. E hoʻomanaʻo ʻoe he aha ke alapine hoʻololi o ka module mana i ke kaapuni hoʻoikaika a i ʻole ke kaapuni buck? He kakaikahi wale no paha haneri K, a o ka hoololi wikiwiki ana he kakaikahi wale no M. Ma ka olelo maʻamau, ua emi loa keia waiwai ma mua o ke alapine o ka inductor mana. No laila, ʻaʻole pono mākou e noʻonoʻo i ke alapine resonant.

Pēlā nō, i ke kaapuni mana hoʻololi, ʻo ka hopena hope loa ka DC o kēia manawa, a ʻo ka ʻāpana AC ke helu nei i kahi hapa liʻiliʻi.

No ka laʻana, no 1W BUCK mana mana, ʻo ka ʻāpana DC he 85%, 0.85W, a ʻo ka ʻāpana AC no 15%, 0.15W. E noʻonoʻo paha ʻo ka helu Q o ka mana inductor i hoʻohana ʻia he 10, no ka mea, e like me ka wehewehe ʻana o ka mea maikaʻi o ka inductor, ʻo ia ka ratio o ka ikehu i mālama ʻia e ka inductor i ka ikehu i hoʻopau ʻia e ka inductor. Pono ka inductance e mālama i ka ikehu, akā ʻaʻole hiki ke hana ka mea DC. Hiki i ka mea AC ke hana. A laila ʻo 0.015W wale nō ka poho AC i hoʻokumu ʻia e kēia inductor, helu no 1.5% o ka nui o ka mana. No ka mea ʻoi aku ka nui o ka waiwai Q o ka mana inductor ma mua o 10, ʻaʻole mākou e mālama nui i kēia hōʻailona.

E kamaʻilio kākoukiʻekiʻe-frequency inductor.
Hoʻohana ʻia nā inductors kiʻekiʻe i nā kaapuni kiʻekiʻe. I nā kaapuni kiʻekiʻe-frequency, liʻiliʻi ka manawa maʻamau, akā kiʻekiʻe loa ka alapine i koi ʻia. No laila, ʻo nā hōʻailona koʻikoʻi o ka inductor e lilo i ka resonance frequency a me ke kumu maikaʻi.

ʻO ke alapine resonant a me ke kumu maikaʻi he mau hiʻohiʻona pili ikaika i ka alapine, a loaʻa pinepine kahi pihi ʻano alapine e pili ana iā lākou.

Pono e hoʻomaopopo i kēia helu. Pono ʻoe e ʻike ʻo ka helu haʻahaʻa loa i ka kiʻina impedance o ke ʻano alapine resonance ʻo ia ka helu alapine resonance. E ʻike ʻia nā kumu waiwai kūpono e pili ana i nā alapine like ʻole ma ke kiʻikuhi ʻano alapine o ka mea maikaʻi. E nānā inā hiki iā ia ke hoʻokō i nā pono o kāu noi.

No nā inductors maʻamau, pono mākou e nānā i nā hiʻohiʻona noiʻi like ʻole, inā paha lākou i hoʻohana ʻia i ke kaapuni kānana mana a i ʻole ka kānana hōʻailona, ​​pehea ka nui o ka hōʻailona, ​​pehea ka nui o kēia manawa, a pēlā aku. No nā hiʻohiʻona like ʻole, pono mākou e hoʻolohe i ko lākou mau ʻano like ʻole.

Inā makemake ʻoe, e ʻoluʻolu e leka uilaMingdano nā kikoʻī hou aku.
