Ukuqonda iikhoyili ze-Inductance: Iziseko
Intshayelelo ye-Inductance
I-induction yiparameter esisiseko yesekethe yombane elinganisa ukukwazi kwesekethe ukugcina amandla xa umsinga uqhutywa kwisekethe. Umbono kanye apha kukungeniswa kwe-electromagnetic kwi-conductor: i-current itshintshiwe, i-voltage ibonakala kuyo. Izixhobo ezaziwa ngokuba zii-inductor okanye iikhoyili ze-inductor zisebenzisa esi senzo. Ngokuqhelekileyo zakhiwe ngocingo olujikelezwe kumbindi onokuba ngumoya, intsimbi okanye enye imathiriyeli yemagnethi. Inani lokujika kunye nezinto eziphambili zizimiselo eziphambili ze-inductor's inductance. Ukwazi ukuba i-inductance isebenza njani ibalulekile ekuqondeni ukuba ii-inductors zisebenza njani kwezinye izicelo ze-elektroniki.
Amalungu eKhoyili ye-Inductance
I-coil ye-inductance yi-coil of inductance wire conductive ehlanganiswe kwi-spiral kunye ne-core apho ucingo lulimale. Isiqwenga sokuqhuba sinokuba yintambo yobhedu, ucingo lobhedu lusetyenziswa ngokubanzi ngenxa yokuqhuba kakuhle kombane kunye nokukwazi ukwenza. Izinto eziphambili zinokwahluka kuluhlu olubanzi ngokuxhomekeka kwiimpawu ezifunwayo ze-coil inductance kwaye kunokwenzeka ukusebenzisa umoya, i-ferrite, isinyithi kunye ne-powder iron njengento engundoqo. Njengoko nganye ikwanezibuthe ezahlukeneyo, ziphembelela icoil inductance nganye. Nantsi itheyibhile yezinto eziqhelekileyo ezingundoqo kunye nokufikeleleka kwazo okuLalelanayo.

Xa umbane uhamba nge-inductor, intsimi yamagnetic yenziwa malunga nekhoyili. Olu gcino lwamandla lunokutsala amandla abuyele kwisekethe xa kukho imfuneko, kwaye lunegalelo ekunikeni ulawulo olwaneleyo lokwahluka konikezelo lwamandla. Ii-inductors zikwasetyenziswa kwiifilitha ezithintela ingxolo ephezulu-frequency kwaye zivumela i-current ngqo (DC) kunye neempawu ezisezantsi ukuba zidlule. Zisetyenziswa kwii-transformers ukudlulisa amandla phakathi kweesekethe ezimbini okanye ngaphezulu ngaphandle kokusetyenziswa koqhagamshelwano. Kulo mongo, inkcazo echanekileyo yokuziphatha kweekhoyili ze-inductance iyimfuneko kuyilo kunye nomzekelo wenani elikhulu lezixhobo zombane kunye neenkqubo.
Iintlobo zeeCoils ze-Inductance
IiCoils zoMoya eziNqabileyo vs. IiCoils zeIron Core
Iikhoyili zomoya kunye nentsimbi engundoqo ye-inductance-iintlobo ezimbini ezisisiseko zoyilo xa kuziwa kwihlabathi le-electromagnetics. I-Air coreInductors.Ingcaciso yeWikipedia Iikhoyili ezingundoqo zomoya (ezo zinomoya uyinto yazo engundoqo) zisebenzisa umgaqo wokuthomalalisa kwaye ikwayeyona ndlela ilula ye-inductor. Kuba zingenawo undoqo we-ferromagnetic, azityekelekanga kwi-core saturation kwaye azinayo ilahleko ye-hysteresis kwaye ziluncedo kwizicelo ezisebenza ngamaza aphezulu (ezifana nosasazo lwerediyo). Ngokwahlukileyo, i-coil engundoqo yentsimbi ibandakanya isiseko esinemathiriyeli ye-ferromagnetic eyandisa kakhulu inductance yekhoyili ekuphenduleni iimpawu zemagnethi zezinto eziphambili. Oku kubenza basebenze ngakumbi ekugqithiseni amandla kunye nokugcinwa kwezicelo kodwa kuyingozi xa kuziwa ekulahlekeni okwandisiweyo okubangelwa yimisinga ye-eddy kunye ne-hysteresis ngokukodwa kwingingqi ephezulu yefrikhwensi.
Iikhoyili ze-Inductance eziguquguqukayo
