Ingcamango ye-Inductor

Ii-inductors ngamalungu anokuguqula amandla ombane abe ngamandla kazibuthe kwaye ayigcine.Ii-inductors ziyafana ngesakhiwo kwi-transformers, kodwa zine-winding enye kuphela.I-inductors ine-inductance ethile, evimba kuphela utshintsho lwangoku.Ukuba i-inductor ikwimeko apho kungekho khona ukuhamba kwangoku, iya kuzama ukuvimba i-current flowing kuyo xa isiphaluka sixhunyiwe.Ukuba i-inductor ikwimeko yokuhamba kwangoku, iya kuzama ukugcina i-current ingatshintshi xa isiphaluka sinqanyuliwe.

Ii-inductors zikwabizwa ngokuba yi-chokes, i-reactors kunye ne-reactors eguqukayo.I-Inductor ngokubanzi yenziwe ngesakhelo, ukujija, isigqubuthelo esikhuselayo, imathiriyeli yokupakisha, undoqo wemagnethi okanye undoqo wentsimbi, njl. njl. I-inductance ngumlinganiselo wemagnethi eguquguqukayo ye-conductor ukuya kwangoku ivelisa imagnethi etshintshanayo ejikeleze i-conductor xa umqhubi edlula. umsinga otshintshanayo.

Xa i-DC yangoku ihamba nge-inductor, kuphela umgca wemagnethi osisigxina ovela ngeenxa zonke kuyo, ongatshintshiyo ngexesha.Nangona kunjalo, xa i-alternating current idlula kwikhoyili, imigca yemagnethi ejikelezayo iya kutshintsha ngokuhamba kwexesha.Ngokomthetho kaFaraday wokungeniswa kwe-electromagnetic – umazibuthe uvelisa umbane, iintambo zombane ezitshintshileyo ziya kuvelisa amandla okungenisa kuzo zombini iziphelo zekhoyili, elilingana “nomthombo wamandla omtsha”.

Ii-inductors zohlulwe zibe zii-self-inductors kunye nee-inductors ezifanayo.Xa kukho yangoku kwikhoyili, amasimi kazibuthe iya kuveliswa ngeenxa ikhoyili.

Xa utshintsho lwangoku kwikhoyili, intsimi yamagnetic ejikelezayo nayo iya kutshintsha ngokufanelekileyo.Lo mmandla wemagnethi utshintshileyo unokwenza icoil ngokwayo ivelise amandla e-electromotive (i-electromotive force) (i-electromotive force isetyenziselwa ukumela i-terminal voltage yobonelelo lwamandla olufanelekileyo lwento esebenzayo), ebizwa ngokuba yi-self induction.

Xa iikhoyili ezimbini ze-inductance zisondele komnye nomnye, utshintsho lwamagnetic lwe-coil inductance luya kuchaphazela enye i-coil inductance, ebizwa ngokuba yi-mutual inductance.Ubungakanani be-inductor ehambelanayo buxhomekeke kwiqondo lokudibanisa phakathi kwe-self inductance ye-coil inductance kunye neekhoyili ezimbini ze-inductance.Amacandelo enziwe ngokusebenzisa lo mgaqo abizwa ngokuba yi-mutual inductor.

Ubume bophuhliso lwemalike yeshishini le-inductor

I-Chip inductors ihlelwa ngesakhiwo se-inductor.Ngokutsho kokuhlelwa kwesakhiwo kunye nenkqubo yokuvelisa, i-inductors ihlukaniswe ngamacandelo amabini: i-plug-in inductors eqinile kunye ne-chip mounted inductors.Ithekhnoloji ephambili yokuvelisa i-plug-in inductors yendabuko "i-winding", oko kukuthi, i-conductor inxeba kwi-core magnetic ukwenza i-coil inductive (eyaziwa nangokuthi i-coil engenanto).

Le inductor ibonakaliswe ngoluhlu olubanzi lwe-inductance, ukuchaneka okuphezulu kwexabiso le-inductance, amandla amakhulu, ilahleko encinci, ukuveliswa okulula, umjikelezo omfutshane wokuvelisa, kunye nokubonelela okwaneleyo kwezinto eziphathekayo.Ukungalungi kwayo yinqanaba eliphantsi lemveliso ezenzekelayo, ixabiso eliphezulu lokuvelisa, kunye nobunzima kwi-miniaturization kunye nobunzima.

I-China Electronics Industry Association iqikelela ukuba imarike ye-inductor yehlabathi iya kukhula nge-7.5% ngonyaka kule minyaka imbalwa izayo, i-China ngumthengi omkhulu wezixhobo zokungenisa.Ngotshintsho olukhawulezayo lwetekhnoloji yonxibelelwano lwaseTshayina kunye nolwakhiwo olukhulu lwe-Intanethi yeZinto, izixeko ezikrelekrele kunye namanye amashishini anxulumeneyo, imakethi ye-chip inductor yaseTshayina iya kukhula ngokukhawuleza kunezinga lokukhula kwehlabathi.Ukuba izinga lokukhula li-10%, ubungakanani bemarike yoshishino lwe-chip inductor luya kudlula i-yuan ye-18 yeebhiliyoni.Ngokwedatha, ubungakanani bemarike ye-inductor yehlabathi ngo-2019 yayiyi-48.64 yeebhiliyoni zeeyuan, inyuke nge-0.1% ngonyaka ukusuka kwi-48.16 yeebhiliyoni zeeyuan ngo-2018;Ngo-2020, ngenxa yempembelelo ye-COVID-19 yehlabathi, ubungakanani bemarike yee-inductors buya kuhla ukuya kwi-44.54 yeebhiliyoni zeeyuan.Isikali sophuhliso lwemarike ye-inductor yaseTshayina.Ngo-2019, isikali semakethi ye-inductor yaseTshayina yayimalunga ne-RMB 16.04 yeebhiliyoni, ukonyuka nge-13% xa kuthelekiswa ne-RMB 14.19 yeebhiliyoni ngo-2018. Ngo-2019, ingeniso yentengiso ye-inductor yase-China inyuke unyaka nonyaka, ukusuka kwi-8.136 yeebhiliyoni zeeyuan ngo-2014 ukuya kwi-5 yezigidigidi ze-1704. ngo-2019.

Kulindeleke ukuba imfuno yemarike yee-inductors iya kuba nkulu kwaye ibe nkulu, kwaye imarike yasekhaya iya kuba banzi.Ngo-2019, i-China yathumela ngaphandle i-73.378 yeebhiliyoni zee-inductors kwaye yathumela ngaphandle i-178.983 yeebhiliyoni zee-inductors, ngokuphindwe ka-2.4 kumthamo wokuthumela ngaphandle.

Ngo-2019, ixabiso lokuthumela ngaphandle kwee-inductors zase-China laliyi-2.898 yeebhiliyoni zeedola zaseMelika kwaye ixabiso lokungenisa laliyi-2.752 yeebhiliyoni zeedola.

Itsheyini yoshishino lwe-elektroniki yabathengi baseTshayina baye bafumana inguqu ekhulayo ukusuka kwimveliso yexabiso eliphantsi, i-OEM yeempawu ze-terminal zangaphandle ukuya ekungeneni kwamakhonkco emveliso yexabiso elongezelelweyo, kunye neempawu ze-terminal zasekhaya ziye zaba ziimpawu eziphambili zehlabathi.Okwangoku, imveliso ye-smartphone yaseTshayina yenza i-70% okanye i-80% yelizwe lonke, kwaye amashishini aseTshayina alawula kwinqanaba eliphakathi kunye nelamva kwikhonkco lemveliso ye-elektroniki yabathengi behlabathi, indibano kunye namanye amacandelo, ke ngoko, phantsi kwemvumelwano yoshishino "yemoto njengefowuni enkulu ephathwayo” kunye nemvelaphi apho amashishini othungelwano lwe-electronics athe asetyenziswa kummandla weemoto ezikrelekrele, ithemba lekhonkco loshishino lwezobuchwephesha basekhaya kwixa elizayo lifanelekile ukuba lijonge phambili.

Ukunyuka kwenani le-5G yeebhendi ze-frequency yefowuni yeselula kukhulise kakhulu ukusetyenziswa kwee-inductors zeyunithi enye.Ii-inductors ze-high-frequency inductors zijongene nomsantsa omkhulu womthamo kunye nokubonelela okuqinileyo.Ukushwankathela, ukutshintshwa kweefowuni eziphathwayo ze-5G zingenise umjikelo wokutshintsha.Imfuno ye-inductance iqhubekile ukunyuka.Ubhubhani wakhokelela ekurhoxisweni kwezinye izigebenga ze-inductance.Iindlela ezizezinye zasekhaya zavula indawo.
