YMIN Cov Capacitors Conductive rau AC/DC Converters Siv GaN

Nrog rau kev loj hlob maj mam ntawm gallium nitride (GaN) thev naus laus zis, ntau tus neeg hloov AC / DC tau txais yuav GaN ua cov khoom hloov pauv los hloov cov khoom siv silicon ib txwm muaj. Hauv kev siv cov thev naus laus zis tshiab no, cov capacitors conductive kuj ua lub luag haujlwm tseem ceeb.

YMIN tau cog lus ntev rau kev tsim cov capacitors conductive rau kev siv hauv GaN-based AC/DC converters thiab tau ua tiav cov ntawv thov ua tiav thoob plaws ntau yam kev lag luam, xws li kev them ceev (los ntawm yav dhau los IQ them ceev, PD2.0, PD3.0, PD3.1), laptop adapters, tsheb kauj vab hluav taws xob them ceev, onboard chargers (OBC) / DC them ceev piles, server fais fab khoom siv, thiab ntau ntxiv. Cov conductive capacitors tshiab no tuaj yeem ua tiav tag nrho cov yam ntxwv zoo ntawm GaN, ua tau zoo heev hauv cov xwm txheej siv tau thiab ua tau raws li cov neeg siv khoom xav tau rau kev txhim kho kev ua tau zoo thiab kev hloov kho dua tshiab. Hauv qab no, peb yuav piav qhia txog lawv cov yam ntxwv ntawm daim ntawv thov.

01 GaN pab ua kom cov AC / DC converters me me

Feem ntau cov circuits siv DC voltage es tsis yog AC voltage, thiab AC/DC converters yog qhov tseem ceeb ua cov khoom siv uas hloov AC fais fab rau cov tsev thiab cov lag luam mus rau hauv DC fais fab. Thaum lub zog zoo ib yam, qhov sib txawv yog kom miniaturize cov converters los ntawm qhov pom ntawm kev txuag chaw thiab kev yooj yim nqa.

Kev siv GaN (gallium nitride) tau ua tiav zoo heev hauv kev ua kom me me ntawm AC/DC converters. Piv nrog rau cov khoom Si (silicon) ib txwm muaj, qhov zoo ntawm GaN yog qhov poob qis dua, ua haujlwm tau zoo dua, ceev dua ntawm kev hloov pauv hluav taws xob thiab cov khoom siv hluav taws xob. Qhov no tso cai rau AC/DC converter tswj hwm kev ua haujlwm hloov pauv zoo dua, ua rau muaj kev hloov pauv hluav taws xob zoo dua.

Ntxiv mus, cov zaus hloov pauv siab tuaj yeem xaiv tau, tso cai rau kev siv cov khoom me me passive. Qhov no yog vim GaN tuaj yeem tswj tau qhov ua tau zoo txawm tias ntawm kev hloov pauv zaus siab, piv rau kev hloov pauv zaus qis ntawm Si.

02 Lub luag haujlwm tseem ceeb ntawmcov capacitors uas ua haujlwm tau zoo

Hauv kev tsim cov AC/DC converters, cov capacitors tso zis yog qhov tseem ceeb heev. Cov capacitors conductive tuaj yeem pab txo qhov ripple ntawm qhov tso zis voltage thiab ua lub luag haujlwm tseem ceeb hauv kev lim dej hauv cov hluav taws xob hloov pauv siab. Thaum lub capacitor nqus cov ripple tam sim no, nws yuav tsim cov ripple voltage. Hauv kev siv tiag tiag, feem ntau yuav tsum tau tias lub zog muab hluav taws xob ripple tsis pub tshaj 1% ntawm qhov ua haujlwm voltage ntawm cov khoom siv.

Yog tias siv GaN, ESR ntawm YMIN cov khoom siv sib xyaw ua ke ntawm cov kua thiab cov kua hluav taws xob ruaj khov nyob rau hauv qhov dav dav ntawm 10KHz ~ 800KHz, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm GAN high-frequency switching.

Yog li ntawd, hauv AC/DC converters siv gallium nitride, cov conductive capacitors dhau los ua cov capacitors tso zis zoo tshaj plaws.

03 YMIN phim nrog cov capacitor conductivity sib xws

Nrog kev siv GaN, kev siv cov hloov pauv AC/DC zaus siab tau maj mam nce ntxiv. Txhawm rau kom txuas ntxiv ua tau raws li cov kev xav tau hloov pauv ntawm cov neeg siv khoom, YMIN, ua tus tsim kev lag luam tshiab hauv cov capacitors conductive, siv nws cov thev naus laus zis ua haujlwm siab / kev ntseeg siab los coj cov neeg siv khoom cov khoom lag luam tshiab, cov khoom lag luam tiav (txog li 100V) thiab cov kev pabcuam zoo.

Peb cov polymer solid aluminium electrolytic capacitors, polymer solid-liquid hybrid aluminium electrolytic capacitors, multilayer polymer solid aluminium electrolytic, thiab polymer tantalum capacitor series khoom tuaj yeem sib phim zoo nrog AC/DC converters tshiab.

Cov capacitors conductive no siv dav hauv 5-20V cov zis siv dav hauv cov khoom siv pej xeem, 24V cov zis rau cov khoom siv kev lag luam, thiab 48V cov zis rau cov khoom siv sib txuas lus. Yuav kom daws tau qhov teeb meem tsis txaus fais fab hauv xyoo tas los no, xav tau kev ua haujlwm zoo dua, thiab tus lej ntawm cov khoom hloov mus rau 48V tab tom nce ntxiv (tsheb, chaw khaws ntaub ntawv, USB-PD, thiab lwm yam), ua rau ntau daim ntawv thov ntawm GaN thiab conductive capacitors dav dua.

04 Xaus Lus
Nyob rau hauv lub caij nyoog tshiab, YMIN ua raws li lub tswv yim kev pabcuam ntawm "Capacitor Solutions, Nug YMIN rau koj daim ntawv thov", txiav txim siab los ua tiav cov kev xav tau tshiab thiab kev tawg tshiab los ntawm cov ntawv thov tshiab thiab cov kev daws teeb meem tshiab, thiab nquag tshawb nrhiav cov kev cia siab ntawm kev ua kom me me ntawm AC / DC converters hauv qab GaN daim ntawv thov. YMIN hais kom tsom mus rau kev tsim khoom tshiab, kev tsim khoom siab thiab kev txhawb nqa daim ntawv thov kawg, muab cov neeg siv khoom nrog cov capacitors conductive zoo, muab cov kev pabcuam tshiab thiab zoo, nce kev nqis peev tshawb fawb, thiab txhawb kev nce qib hauv kev lag luam.
