Hiki ke ʻike ʻia mai ka pihi ʻano impedance o nā pahu magnetic kake alapine o ka helu hoʻololi ma mua o ka inductance, a ʻoi aku ka kiʻekiʻe o ke alapine o ka wahi hoʻololi ma mua o ke kū'ē. ʻO ka hana o ka inductance ka noʻonoʻo ʻana i ka walaʻau, ʻoiai ʻo ke kūpaʻa e hoʻopaʻa i ka walaʻau a hoʻololi iā ia i ka wela. He aha ka like o nā inductors a me nā lei magnetic? He aha ko lākou ʻokoʻa? E hahai kākou i nā mea hana hoʻopili e hoʻomaopopo!
ʻO ka ʻokoʻa ma waena o ka inductor a me ka bead magnetic
1. ʻO nā mea ʻike he mau ʻāpana mālama ikehu, a ʻo nā peʻa magnetic he mau mea hoʻololi ikehu (hoʻohana). Hiki i nā kānana ke hoʻohana i nā inductors a me nā beads, akā ma nā ʻano hana like ʻole. Hoʻololi ka kānana inductor i ka ikehu uila i ka ikehu magnetic, e pili ana i ke kaapuni ma nā ʻano ʻelua: ma ka hoʻohuli ʻana i ka ikehu uila i ka ikehu uila, a ma ka hoʻomālamalama ʻana i waho-e like me EMI (EMI). Eia kekahi, ua hoʻololi ʻia ka ikehu uila i ikehu wela me ka ʻole o ke keakea lua i ke kaapuni.
2. He maikaʻi loa ka hana kānana o ka inductor ma ke alapine haʻahaʻa haʻahaʻa, akā i ka wā i ʻoi aku ka hana o ka kānana ma mua o 50MHz, hoʻohana ka bead magnetic i kāna ʻāpana impedance e hoʻohuli i ka leo kiʻekiʻe i ka ikehu wela, a ua hoʻokō i ka pahuhopu e hoʻopau i ke kiʻekiʻe. - ka leo alapine loa.
3. Mai ka hiʻohiʻona o EMC(EMC), hiki ke hoʻololi i ka leo kiʻekiʻe-frequency i ka ikehu wela, no laila, loaʻa iā lākou ke kūpaʻa radiation maikaʻi. Hoʻohana maʻamau lākou i nā mea anti-EMI a hoʻohana pinepine ʻia e kānana i nā hōʻailona hoʻohana. Kānana mana o ka mīkini uaki māmā holo kiʻekiʻe ma luna o ka moku.
4. Ke hana ka inductor a me ka capacitor i kānana pass haʻahaʻa, hiki i ka hui ʻana o kēia mau ʻāpana ʻelua ke hoʻoulu iā ia iho no ka mea ʻo ia mau mea ʻelua e mālama i ka ikehu; He mau mea hoʻoheheʻe i ka ikehu a ʻaʻole e hoʻoulu i ka hoʻoulu ʻana iā ia iho i ka wā e hana ai me nā capacitors.
5. ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ka manawa i helu ʻia o ka inductor i hoʻohana ʻia no ka hoʻolako ʻana i ka mana, no laila, i loko o ke kaapuni mana e koi ai i ka manawa kiʻekiʻe, e like me ka hoʻohana ʻana no ka kānana module mana; Hoʻohana maʻamau ʻia nā peʻa magnetic wale nō no nā kānana mana chip-level (akā naʻe, aia nā helu nui o kēia manawa ma ka mākeke).
6. Loaʻa i nā peʻa magnetic a me nā inductors ke kūʻē DC, ʻoiai ʻoi aku ka liʻiliʻi o ke kūpaʻa dc o nā peʻa magnetic ma mua o ka hana kānana, no laila he liʻiliʻi ke kaomi ʻokoʻa o nā peʻa magnetic ke hoʻohana ʻia i ka kānana mana.
7. Ke hoʻohana ʻia no ka kānana, ʻoi aku ka liʻiliʻi o ka hana o ka inductor ma mua o ka manawa i helu ʻia, inā ʻaʻole hiki ke hōʻino ʻia ka inductor, akā e hoʻohālikelike ʻia ka waiwai inductance.
ʻO ke kumu maʻamau o ka inductor a me ka bead magnetic
1. Ua helu ʻia i kēia manawa. Inā ʻoi aku ka nui o ke au o ka inductor i kona manawa i helu ʻia, e emi koke ka inductance, akā ʻaʻole pono e pōʻino ka inductor, a ʻoi aku ka hana o ka pahu magnetic ma mua o ka manawa i helu ʻia, e hoʻopōʻino ʻia ka bead magnetic.
2. Dc kū'ē. Ke hoʻohanaʻia i ka laina mana, aia kekahi manawa ma ka laina, inā he nui loa ke kū'ē dc o ka inductor a iʻole ka magnetic bead pono'ī, e hoʻopuka i kahi hāʻule uila.
3. Pipi hiʻona alapine. Hoʻopili ʻia ka ʻikepili hana o ka pōleʻa induction a me ka pōpō magnetic me ka pihi kikoʻī o ka mīkini. No ke koho ʻana i ka hāmeʻa pono pono ʻoe e nānā pono i kēia mau pihi e koho i ka hāmeʻa kūpono. Ke hoʻohana ʻia, e hoʻolohe i kona alapine resonant.
Aia ma luna aʻe ka hoʻolauna ʻana o nā inductors a me nā beads magnetic, inā makemake ʻoe i ʻike hou aku e pili ana i nā inductors, e ʻoluʻolu e kelepona i kā mākou mea hoʻolako inductor ʻoihana.

Makemake paha ʻoe
Hana kūikawā ana i loko o ka? Iecaianoaaiiie o acee? Iuo oeiia o kaʻeleʻele o ke komo lima inductors, lei inductors, vertical inductors, Tripod inductors, one inductors, ka hoaka o inductors, e like me ka pololei coils, kiʻekiʻe-alapine (frequency) transformers a me nāʻume mākenēki eiiiiiaiou.
