Nyob rau hauv kev teb rau lub ntiaj teb no qauv ntawm kev txawj ntse kev txuag hluav taws xob, kev sib txuas lus wireless thiab portable mobile device khoom yuav tsum tau tsim nrog high efficiency thiab tsawg zog noj. Yog li ntawd, lub hwj chim inductor lub luag hauj lwm rau lub zog cia hloov dua siab tshiab thiab rectification filtering nyob rau hauv lub hwj chim module plays lub luag hauj lwm tseem ceeb ntawm lub zog txuag.

Tam sim no, qhov kev ua tau zoo ntawm cov khoom siv hlau nplaum ferrite maj mam ua tsis tau raws li cov kev xav tau me me thiab siab tam sim nolub zog inductorcov khoom. Nws yog ib qho tsim nyog yuav tsum tau hloov mus rau cov hlau nplaum hlau nrog cov kab hluav taws xob sib nqus siab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhim kho micro / siab tam sim no cov khoom thiab tsim cov khoom siv hluav taws xob siab, miniaturized, ntim ntim siab, thiab cov khoom siv hluav taws xob siab. .

Tam sim no, thev naus laus zis ntawm kev sib xyaw hlau inductors tau dhau los ua neeg paub tab, thiab lwm txoj kev txhim kho yog qhov kub-kub co raug rho tawm haujlwm nti raws li hlau fais fab inductors. Piv nrog rau kev sib xyaw inductors, cov hom inductors muaj qhov zoo ntawm qhov yooj yim miniaturization, zoo heev saturation tam sim no, thiab cov txheej txheem qis. Lawv tau pib tau txais kev saib xyuas los ntawm kev lag luam thiab tau nqis peev hauv kev tshawb fawb thiab kev loj hlob. Nws ntseeg tau hais tias nyob rau hauv lub neej yav tom ntej, hlau fais fab inductors yuav siv dav hauv ntau yam khoom siv txawb, kom tau raws li cov qauv ntawm kev txawj ntse thiab kev txuag hluav taws xob.

Cov Ntsiab Cai ntawm Fais Fab Inductor Technology

Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm lub hwj chim inductor siv nyob rau hauv lub hwj chim module tsuas yog khaws cov hluav taws xob nyob rau hauv daim ntawv ntawm lub zog sib nqus nyob rau hauv cov khoom siv hlau nplaum. Muaj ntau hom ntawv thov rau inductors, thiab cov khoom siv hlau nplaum thiab cov khoom siv hauv txhua qhov xwm txheej muaj cov qauv tsim. Feem ntau hais lus, cov hlau nplaum ferrite muaj qhov zoo tshaj Q, tab sis cov kab hlau nplaum saturated tsuas yog 3000 ~ 5000 gauss; Lub saturated magnetic beam ntawm cov hlau nplaum muaj peev xwm ncav cuag ntau tshaj 12000 ~ 15000 Gauss, uas yog ntau tshaj ob npaug ntawm cov hlau nplaum ferrite. Raws li txoj kev xav ntawm kev sib nqus saturation tam sim no, piv rau cov hlau nplaum ferrite, cov hlau nplaum hlau nplaum yuav zoo dua rau cov khoom siv me me thiab cov qauv tsim tam sim no.

Thaum qhov tam sim no dhau los ntawm lub hwj chim module, kev hloov pauv sai ntawm transistors ua rau lub sijhawm luv lossis tam sim no ncov siab tam sim no hloov pauv hauv lub zog inductor, ua rau cov yam ntxwv ntawm inductor nyuaj thiab nyuaj rau tswj.

Lub inductor yog tsim los ntawm cov khoom siv hlau nplaum thiab cov coils. Lub inductor yuav ib txwm resonate nrog lub stray capacitance uas twb muaj lawm ntawm txhua kauj, tsim ib tug parallel resonance circuit. Yog li ntawd, nws yuav tsim kom muaj tus kheej resonant zaus (SRF). Thaum qhov zaus siab dua qhov no, lub inductor yuav nthuav tawm lub peev xwm, yog li nws tsis tuaj yeem muaj lub zog cia ua haujlwm. Yog li ntawd, kev khiav hauj lwm zaus ntawm lub hwj chim inductor yuav tsum qis dua tus kheej resonant zaus kom ua tiav lub zog cia.

Nyob rau hauv lub neej yav tom ntej, mobile kev sib txuas lus yuav tsim mus rau 4G / 5G high-ceev cov ntaub ntawv kis tau tus mob. Kev siv cov inductors hauv high-end ntse xov tooj thiab kev ua lag luam tau pib qhia kev loj hlob muaj zog. Qhov nruab nrab, txhua lub xov tooj ntse xav tau 60-90 inductors. Ntxiv nrog rau lwm cov modules xws li LTE lossis graphics chips, kev siv cov inductors nyob rau hauv tag nrho cov xov tooj tseem ceeb dua.

Tam sim no, chav tsev nqi thiab nyiaj tau los ntawminductorsyog qhov siab dua piv rau cov capacitors lossis resistors, nyiam ntau lub tuam txhab los nqis peev hauv kev tshawb fawb thiab kev tsim khoom. Daim duab 3 qhia txog IEK qhov kev ntsuam xyuas ntawm lub ntiaj teb inductor tso zis tus nqi thiab kev ua lag luam, qhia txog kev lag luam loj hlob. Daim duab 4 qhia txog kev tsom xam ntawm qhov ntsuas ntawm kev siv inductor rau ntau yam khoom siv mobile xws li smartphones, LCDs, lossis NB. Vim muaj kev lag luam loj loj hauv kev lag luam inductor, lub ntiaj teb inductor manufacturers tau nquag tshawb nrhiav cov neeg siv khoom siv tes ua thiab ua txhua yam los nqis peev hauv kev tshawb fawb thiab kev tsim kho tshiab.lub zog inductorcov khoom lag luam los tsim cov khoom siv hluav taws xob muaj txiaj ntsig thiab tsis muaj zog ntse ntse.

Kev siv cov khoom siv hluav taws xob inductors feem ntau yog hauv tsheb, kev lag luam, thiab cov khoom siv hluav taws xob. Hom thiab specifications ntawm lub hwj chim inductors sib haum rau txhua daim ntawv thov teeb meem yog txawv. Tam sim no, daim ntawv thov kev lag luam loj tshaj plaws yog cov neeg siv khoom lag luam.
