Dab tsi yog cov ntawv thov ntawm planar transformers?

1. Dab tsi yog planar transformer？

Planar transformer yog hom tshiab ntawm kev ua haujlwm siab siab ferrite inductance tiv thaiv kev lag luam uas tau sim siv. Vim tias lub xwmfab zoo li tus qauv planar transformer, nws haum rau planar mounting, yooj yim rau kev tsim, thiab ua rau ntau hom khoom siv hluav taws xob yuav ua lub teeb, nyias thiab me. Piv nrog rau cov hloov pauv hloov pauv, ntxiv rau qhov zoo ntawm cov txheej txheem tsim, cov tshuab hluav taws xob hloov pauv tseem muaj qhov zoo ntawm qhov siab tam sim no, kev ua haujlwm siab, qis to tsis txaus, ua kom tsis muaj cua sov, thiab cov cua sov kom zoo.

Raws li cov txiaj ntsig kev ua tau zoo no, cov tshuab hluav taws xob hloov pauv tau ua rau muaj kev xav thiab ua tiav cov ntawv thov me me hauv ntau qhov chaw xws li cov khoom siv hluav taws xob, tsheb kho hluav taws xob, khoom siv kho mob, thiab kev tswj hwm kev lag luam.

Hauv kev lag luam ntawm cov neeg siv khoom siv hluav taws xob, kev siv cov tsoos winding transformer tsim ntawm qhov chaw them nyiaj ceev, hloov pauv yuav luag xav nyob ze li ib feem peb ntawm sab hauv, uas tsis yooj yim rau cov khoom lag luam miniaturization tsim. Thiab yog tias tib lub zog ceev them cov khoom tsim nrog cov twj siv hluav taws xob hloov pauv siv, tsis yog tsuas yog cov kab lus tau yooj yim dua, tab sis ntim kuj tuaj yeem ua kom zoo dua.

2. Daim ntawv thov ntawm planar transformer hauv gallium nitride ceev tau them

Nrog rau qhov yuav tsum tau ua ntawm lub zog hluav taws xob ceev ceev rau lub zog ceev sib piv, txuas nrog cov ntawv thov ntawm GaN thib peb tiam semiconductors hauv kev them ceev ceev, qhov hloov pauv ntawm lub zog hluav taws xob tau zoo heev, thiab ntau tshaj li 100KHz tau dhau los ua qhov pib tshiab. Cov. Qhov nce ntawm qhov hloov mus ntxiv kuj coj cov kev cov nyom tshiab rau xaiv cov hloov pauv.

Raws li kev sib cais ntawm gallium nitride ceev them los ntawm them lub taub hau ntawm lub network, nws tuaj yeem pom tias cov tshuab hluav taws xob hloov pauv tsis tsuas yog muaj kev lag luam nyob rau ntawm lub loj, tab sis kuj qhia ob hom kev siv, uas yog yooj yim PCB + sib nqus. cov tub ntxhais ua ke, thiab PCB + sib nqus tub ntxhais sib xyaw + sib dhos rectification Circuit Court ua ke. Ob leeg nyias muaj nyias qhov zoo nyob hauv kev siv tshwj xeeb, thiab kuj tseem muaj cov sawv cev thov kev sib txawv.

Cia' s coj los saib dua rau kev ntshiab PCB + sib nqus khoom sib xyaw ua ke planar transformer ua ntej. Hom kev hloov pauv no muaj cov yam ntxwv ntawm kev muaj zog ntau yam thiab yooj yim rau kev tsim cov huab hwm coj, thiab feem ntau tuaj yeem pom nyob rau hauv kev ua haujlwm siab ceev.

Cia' s soj ntsuam saib lub chaw tsim hluav taws xob hloov pauv ntawm PCB + sib nqus tub ntxhais sib nqus + synchronous rectifier circuit. Hom transformer no tsis ntev los no tau pib siv rau hauv cov tshuab fais fab loj. Qhov sib txawv ntawm cov phiaj xwm tshiab dhau los yog tias PCB rau ntawm qhov hloov hluav taws xob tseem nqa tau qhov kev faib tawm ntawm kev ua haujlwm ntawm Circuit Court. Nws tuaj yeem pom tau tias muaj ntau yam RC thiab hluav taws xob muaj nyob ntawm nws.

3. Kev siv hluav taws xob ntau ceev ceev them cov lag luam xav tau cov phiaj xwm transformers

Planar magnetism yog lub vias sawv cev ntawm ntau qhov ntau ntawm lub cev, thiab nws tseem yog ib daim teb ntawm kev tshawb nrhiav tshiab hauv kev kawm. Kev siv cov khoom siv hluav taws xob hloov pauv yog ib qho ntawm cov kev daws teeb meem zoo tshaj plaws rau kev ua haujlwm siab thiab siab ntawm lub zog ceev hwj chim hloov khoom.

Tshwj xeeb hauv kev lag luam ntawm cov neeg siv hluav taws xob cov khoom siv hauv ob lub xyoo dhau los, nrog qhov tawg ntawm USB PD them ceev ceev ua lag luam thiab kev paub tab ntawm kev siv tshuab GaN, kev siv hluav taws xob, kev siv hluav taws xob, thiab cov khoom siv fais fab me me tau dhau los ua qhov tshiab rau kev tsim kho ua lag luam. Lub tshuab hluav taws xob hloov pauv maj mam dhau los ua cov cuab yeej ua kom pom zoo los ntawm cov kws tshaj lij, thiab tau raug lees paub los ntawm ntau lub tuam txhab kev lag luam hauv lub tuam txhab, thiab tau pib qhia lawv cov txuj ci hauv PD them ceev thiab gallium nitride them khoom ceev.

Cov ntaub ntawv rhuav tshem yav dhau los ntawm lub charger lub taub hau network qhia tau tias tam sim no, ntau thawj lub xov tooj ntawm tes lub xov tooj thiab PC hom xws li Huawei, Xiaomi, Samsung, OPPO, vivo, Lenovo, thiab lwm yam tau qhia ncaj qha hloov pauv nyob rau hauv ntau yam ntawm them nyiaj ceev. cov peev txheej, thiab tsim kho ntau tus ntawm lawv hauv kev koom tes Lub thawv ntawm cov qauv hluav taws xob tau nruab nrog lub roj teeb kom ua tiav lub zog hluav taws xob ntau dua thiab ua kom cov khoom sib zog dua thiab nqa tau yooj yim.

Lub tshuab hluav taws xob hloov pauv yog cov neeg siv khoom ntawm Samsung ntau dua. Txij li 15W Samsung AFC them nyiaj ceev, ntau ntawm cov khoom siv hluav taws xob hloov pauv tau qhia, thiab nws kuj tau tsim ua ntej rau kev lag luam loj siv cov phiaj xwm transformers hauv kev them nyiaj ceev. Nws qhia tau tias Samsung muaj qhov tshwj xeeb nyiam rau cov ntawv cog lus hloov pauv. Cov.

Huawei kuj tau qhia txog ntau yam ntawm kev siv roj ceev kom ceev nrog cov tshuab hluav taws xob hauv chaw tsim hluav taws xob. Los ntawm qhov tseeb 66W super ceev them rho tawm, nws tuaj yeem pom tias cov tshuab hluav taws xob hauv tshuab hluav taws xob tsuas yog nyob hauv tsawg dua li ib feem plaub ntawm tag nrho PCB pawg module, uas yog qhov chaw txuag ntau. Thaum kawg, tus them nqi ua tiav qhov qauv tsim dua.

Ua tsaug rau kev siv cov phiaj xwm sab hauv hloov kho, OPPO 50W biscuit gallium nitride ceev tau paub txog lub cev tsim ultra-nyias lub cev, thiab lub thickness ntawm tag nrho lub tshuab tsuas yog 10 hli, uas tsuas yog tsis yooj yim sua rau cov tsoos winding transformers. Ntxiv nrog rau lub cev nyias nyias, lub hom phiaj hloov hluav taws xob kuj tau pab lub pob hluav taws xob no kom ua tiav lub zog ceev txog li 1.48W / cm, thiab dhau los ua qhov kev txwv rau qhov muaj zog loj.

Tsav los ntawm kev tsim kho kev lag luam thiab ntau lub hom phiaj ntawm lub hom phiaj, cov tshuab hluav taws xob hloov pauv tau pib siv los ntawm ntau thiab ntau tus neeg sab nraud ceev them cov khoom siv tuam txhab ua khoom nyob rau hauv lub siab ceev them cov khoom siv, thiab kev ua lag luam xav tau kuj nce ntxiv.
