Yintoni i-Inductor?

Inkcazo kunye noMsebenzi oSisiseko

I-inductor licandelo le-elektroniki elisebenzayo eligcina amandla ngendlela yemagnethi xa umbane utyhutyha kuwo. Ngokuqhelekileyo yenziwe ngekhoyili yenxeba elijikeleze umbindi, onokuba ngumoya, intsimbi, okanye i-ferrite. Umsebenzi ophambili we-inductor kukuchasa utshintsho lwangoku, ipropathi eyaziwa ngokuba yi-inductance, elinganiselwa kwi-henries (H).

Ii-inductors zibalulekile kwiisekethe apho ugcino lwamandla, ukuhluza, okanye ukusetyenzwa komqondiso kufuneka. Zihlala zisetyenziselwa kunye ne-capacitors kunye ne-resistors ukwenza izihlungi, i-oscillators, kunye ne-transformers. Ngokomzekelo, kwizinto zombane, ii-inductors zinceda ukuguquguquka kwe-voltage, ukuqinisekisa ukusebenza okuzinzile.

Ii-Inductors zigcina njani amandla

Ii-inductors zigcina amandla kwiindawo zazo zemagneti xa ikhoyo ngoku ihamba ngayo. Le nkqubo yenzeka ngenxa yoMthetho kaFaraday wokungeniswa, othi indawo eguqukayo yamagnetic ibangela umbane kumqhubi. Xa ukwanda kwangoku, intsimi yamagnetic iyanda, igcina amandla. Ngokwahlukileyo, xa ikhoyo iyancipha, i-magnetic field iyawa, ikhuphe amandla agciniweyo abuyele kwisekethe.

Isixa samandla agcinwe kwi-inductor singabalwa kusetyenziswa ifomula:

[ E = \ frac {1}{2} LI^2 ]

Apho:

• ( E ) = Amandla agcinwe (kwijoules)
• ( L ) = Inductance (kwi-henries)
• (I) = Okwangoku (kwi-amperes)

Esi sikhundla sokugcina amandla senza ukuba ii-inductors zixabiseke kwizicelo ezifana nokubonelela ngombane, apho zinceda ukugcina amanqanaba ombane angaguqukiyo ngaphandle kokuguquguquka kwangoku. Ngezantsi kuthelekiso lokugcinwa kwamandla kwii-inductors ngokuchasene ne-capacitors:

Ngokuqonda ukuba ii-inductors zigcina kwaye zikhulule njani amandla, iinjineli zinokuyila iinkqubo zombane ezisebenza kakuhle nezithembekileyo.

I-Inductance kunye nendima yayo kwiiSekethe

I-inductance yipropathi esisiseko yee-inductors echaza amandla abo okugcina amandla kwindawo yamagnetic xa umbane uhamba kuwo. Le ndlela yokugcina amandla ibalulekile kwizicelo ezininzi zombane, njengoko ivumela ii-inductors ukuba zixhathise utshintsho lwangoku, uzinzise iisekethe, kunye neempawu zokucoca.

Xa yangoku idlula kwi-inductor, ivelisa intsimi yamagnetic ejikeleze ikhoyili. Amandla ale ntsimi kuxhomekeke kwinani lokujika kwikhoyili, izinto ezingundoqo (ukuba zikhoyo), kunye nomsinga ngokwawo. Ukuba utshintsho lwangoku, intsimi yamagnetic iphinda itshintshe, ifake i-voltage echasene notshintsho lwangoku. Lo mcimbi waziwa ngokubaukuziqhelanisakwaye ilinganiswa ngeuhenries (H).

Ii-inductors zidlala indima ebalulekileyo kwiisekethe ngokuthi:
