He aha nā ʻāpana hiʻohiʻona ʻelima o ka inductor | GETWELL

'Lelo ka mea hana hana hana hana maʻamau iā ʻoe

ʻO ka ʻeha o ka ʻili i loko o ke ʻano spiral he inductive, a ua kapa ʻia ka coil i hoʻohana ʻia no nā hana mea hoʻokomo . Hoʻohana nui ʻia nā inductors i nā kaʻa uila, a hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana, ʻo kekahi nā inductors no nā ʻōnaehana hōʻailona, ​​​​a ʻo kekahi ʻo nā inductors mana no nā ʻōnaehana mana.

Hoʻohana nui ʻia ka Inductor ma ke ʻano he ʻāpana, a ʻaʻole maʻalahi kekahi o kāna mau ʻāpana kumu, e hopena i ka lawa ʻole o ka hoʻolālā a me nā pilikia koʻikoʻi o ka huahana.

Ke lawe nei i ka mana inductor ma ke ʻano he laʻana, ua hoʻokomo ʻia nā ʻāpana kumu o ka inductor.

waiwai inductance

ʻO ka ʻāpana kumu o ka inductance kekahi mea koʻikoʻi e pili ana i ka ripple o kēia manawa a me ka pane hoʻouka.

ʻO ke au o ka mana inductor i loko o ka mea hoʻololi, ʻo ia ke au nalu triangle. Ma keʻano laulā, hiki ke hoʻonohonoho ʻia ke au ripple ma kahi o 30% o ke au o ka ukana. No laila, ʻoiai ke hoʻoholo ʻia nā kūlana o ka mea hoʻololi, hiki ke helu ʻia ka inductance kūpono o ka inductor mana. Koho ʻia e like me ka waiwai kuhikuhi o ka mea hana, inā makemake ʻoe e hoʻololi i kahi hiʻohiʻona inductor hou, ʻaʻole ʻokoʻa kona mau palena mai ka waiwai kuhikuhi i ʻōlelo ʻia e ka mea hoʻolako.

ke au hoʻokahi

Ua kapa ʻia ka ʻano saturation o kēia manawa i kahi ʻano superposition DC, e pili ana i ka inductance kūpono i ka wā e hana ai ka inductor. Inā ʻaʻole i koho pono ʻia ka inductor, maʻalahi ka hoʻopiha ʻana i ka inductor, e hoʻemi ana i ka waiwai inductance maoli, ʻaʻole hiki ke hoʻokō i nā koi hoʻolālā, a hiki ke puhi i ke kaapuni. ʻOkoʻa iki ka wehewehe ʻana o ke kaapuni saturated, ma ka ʻōlelo maʻamau, pili ia i ka manawa ke hoʻemi ʻia ka inductance mua e 30%.

piʻi wela ke au

He palena kēia e kuhikuhi ana i ka laulā o ka wela ambient i ka wā e hoʻohana ai i nā inductors. ʻO ka wehewehe ʻana o ka piʻi ʻana o ka mahana i kēia manawa mai ka mea hana i ka mea hana, ma ka ʻōlelo maʻamau, pili ia i ke kaapuni i ka wā e piʻi ai ka mahana o ka inductor e 30 ℃. ʻOkoʻa ka hopena o ka mahana me ka ʻenehana hana o ke kaapuni, no laila pono ke koho ʻia ma hope o ka noʻonoʻo ʻana i ke ʻano hoʻohana maoli.

DC impedance

Hōʻike i ka waiwai kū'ē i ka wā e hele ai i ke au pololei. ʻO ka mana nui a pololei loa o kēia ʻāpana ʻo ia ka poho wela, no laila ʻoi aku ka liʻiliʻi o ka impedance DC, ʻo ka liʻiliʻi o ka poho. Aia kahi paio liʻiliʻi ma waena o ka hōʻemi ʻana o Rdc a me ka miniaturization. E like me ka lōʻihi mai nā inductors i ʻōlelo ʻia ma luna nei e hoʻokō i nā ʻano pono e like me ka inductance a me ka helu i kēia manawa, hiki ke koho ʻia kahi huahana me kahi Rdc liʻiliʻi.

ʻAno alapine impedance

Hoʻonui ka impedance o ka inductor kūpono me ka piʻi ʻana o ka pinepine. Eia nō naʻe, ma muli o ka noho ʻana o ka capacitance parasitic a me ke kū'ē parasitic, ʻo ka inductor maoli ka inductive i kekahi alapine, capacitive ma mua o kahi alapine, a ke emi nei ka impedance me ka piʻi ʻana o ke alapine. ʻO kēia alapine ke alapine huli.

ʻO ka mea i luna nei ka hoʻokomo ʻana i nā ʻāpana hiʻohiʻona ʻelima o ka inductor. inā makemake ʻoe e ʻike hou aku e pili ana i ka inductor, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.

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.
