Ii-inductors ngamalungu anokuguqula amandla ombane abe ngamandla kazibuthe kwaye ayigcine. Ii-inductors ziyafana ngesakhiwo kwi-transformers, kodwa zine-winding enye kuphela. I-Inductor ine-inductance ethile, evimba kuphela utshintsho lwangoku. Ukushwankathela, iifowuni eziphathwayo ze-5G zihlaziywa kwaye ziphindaphindwa, zingenisa umjikelo wokutshintsha, kwaye imfuno yee-inductors iyaqhubeka nokukhula.

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 ngokuqhelekileyo 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 lilonke, kwaye amashishini aseTshayina alawula kwinqanaba eliphakathi kunye nasemva kwexesha lomxokelelwane wemveliso 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.
