ʻO ke ʻano maʻamau inductor a i ʻole Choke
Inā e ʻeha ʻia kekahi mau wili ma ka ʻaoʻao hoʻokahi a puni ke apo magnetic i hana ʻia mai loko mai o kekahi mea magnetic, i ka wā e hoʻololi ai ke au i loko, hoʻokumu ʻia ka flux magnetic i loko o ka coil ma muli o ka hoʻokomo electromagnetic.No nā hōʻailona o ke ʻano ʻokoʻa, ua like ka nui o ka flux i hana ʻia a kūʻē i ka ʻaoʻao, a hoʻopau nā mea ʻelua i kekahi i kekahi, e hopena i kahi impedance mode ʻokoʻa liʻiliʻi i hana ʻia e ke apo magnetic.No nā hōʻailona mode maʻamau, ua like ka nui a me ke kuhikuhi o ka flux magnetic i hana ʻia, a ʻo ka superposition o nā hopena ʻelua i kahi impedance mode maʻamau o ke apo magnetic.Hoʻemi kēia hiʻohiʻona i ka hopena o ka inductance mode maʻamau i nā hōʻailona mode ʻokoʻa a loaʻa iā ia ka hana kānana maikaʻi e kū'ē i ka walaʻau ʻano maʻamau.
ʻO ka inductor mode maʻamau he kānana bidirectional: ma ka ʻaoʻao hoʻokahi, pono ia e kānana i ke ʻano maʻamau electromagnetic interference ma ka laina hōʻailona, a ma ka ʻaoʻao ʻē aʻe, pono ia e kāohi i ka hoʻopili electromagnetic iā ia iho mai ka hoʻokuʻu ʻana i waho e pale aku. e pili ana i ka hana maʻamau o nā mea uila ʻē aʻe i loko o ke kaiapuni electromagnetic like.
Hōʻike ʻia nā pōmaikaʻi kikoʻī ma lalo nei:
(1) Loaʻa i ka annular magnetic core ka hoʻohui electromagnetic maikaʻi, ka hana maʻalahi a me ka hana kiʻekiʻe;
(2) ʻO ke alapine hana kiʻekiʻe, ka nui o ka mana kiʻekiʻe, ke alapine ma waena o 50kHz ~ 300kHz.
(3) ʻO nā hiʻohiʻona hoʻoheheʻe wela maikaʻi loa, me kahi kiʻekiʻe o ka ʻili a me ka ratio leo, kahi ala wela pōkole loa, kūpono no ka hoʻopau ʻana i ka wela.
(4) Nalo hoʻokomo ultra-haʻahaʻa;
(5) High impedance hiʻona o kiʻekiʻe-frequency inductance;
(6) Ka maikaʻi maikaʻi me ka uku kūpono;
(7) Ka hale paʻa.
(1) Ke hoʻohana ʻana i ke kumu ferrite kiʻekiʻe, ka wili ʻana o ka uea pālahalaha;
2
(3) Hiki ke hoʻokō ʻia ka hana ʻakomi me ka nui o kēia manawa a me ka inductance kiʻekiʻe;
(4) Me ka hana anti-EMI kiʻekiʻe o kēia manawa a maikaʻi loa;
(5) Hoʻohālikelike o nā ʻāpana i puʻunaue ʻia;
(6) Kiʻekiʻe kiʻekiʻe o kēia manawa, kiʻekiʻe pinepine, kiʻekiʻe impedance;
(7) Kiʻekiʻe Curie wela;
(8) Haʻahaʻa wela piʻi, haʻahaʻa poho, etc.
Hoʻohana maʻamau i nā lako mana hoʻololi kamepiula e kānana i nā hōʻailona hoʻopilikia electromagnetic mode maʻamau.Ma ka hoʻolālā papa, lawelawe ʻia nā inductors mode maʻamau e like me nā kānana EMI e kāohi i ka radiation a me ka hoʻokuʻu ʻana o nā hawewe electromagnetic i hana ʻia e nā laina hōʻailona kiʻekiʻe.
Hoʻohana nui ʻia i ka mana ea air conditioner, TV power supply, UPS power supply, etc.
