YMIN Conductive Capacitors rau AC / DC Converters Siv GaN

Nrog rau kev loj hlob zuj zus ntawm gallium nitride (GaN) thev naus laus zis, ntau cov AC / DC converters tau txais GaN los hloov cov khoom siv los hloov cov khoom siv silicon. Nyob rau hauv daim ntawv thov ntawm no technology tshiab, conductive capacitors kuj ua lub luag hauj lwm tseem ceeb.

YMIN tau cog lus ntev rau kev txhim kho cov khoom siv hluav taws xob siv rau hauv GaN-raws li AC / DC converters thiab tau ua tiav daim ntawv thov kev vam meej thoob plaws ntau lub lag luam, xws li kev them nyiaj ceev (los ntawm yav dhau los IQ ceev them, PD2.0, PD3.0, PD3.1), laptop adapters, hluav taws xob tsheb kauj vab ceev them, onboard chargers (OBC) / DC ceev them pawg, cov khoom siv hluav taws xob server, thiab lwm yam. Cov khoom siv hluav taws xob tshiab no tuaj yeem ua tiav cov yam ntxwv zoo ntawm GaN, ua tau zoo heev hauv kev siv cov xwm txheej thiab ua tau raws li cov neeg siv khoom xav tau rau kev txhim kho kev ua haujlwm thiab rov ua dua tshiab. Hauv qab no, peb yuav nthuav dav lawv cov yam ntxwv ntawm daim ntawv thov.

01 GaN pab miniaturize AC / DC converters

Feem ntau cov circuits siv DC voltage hloov AC voltage, thiab AC / DC converters yog qhov tseem ceeb raws li cov khoom siv uas hloov AC fais fab kev lag luam muab rau cov tsev thiab cov lag luam rau hauv DC fais fab. Thaum lub hwj chim zoo ib yam, qhov sib txawv yog me me converters los ntawm qhov kev xav ntawm qhov chaw txuag thiab portability.

Kev siv GaN (gallium nitride) tau ua kom muaj kev vam meej hauv kev ua haujlwm me me ntawm AC / DC converters. Piv nrog rau cov tsoos Si (silicon) Cheebtsam, qhov zoo ntawm GaN yog qhov kev hloov pauv me me, kev ua tau zoo dua, ntau dua electron migration ceev thiab conductive zog. Qhov no tso cai rau AC / DC converter kom zoo dua tswj kev hloov pauv, ua rau muaj zog hloov pauv ntau dua.

Tsis tas li ntawd, kev 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 hwm kev ua haujlwm siab txawm tias nyob rau ntawm qhov hloov pauv hloov pauv ntau zaus, piv rau kev hloov pauv tsawg zaus ntawm Si.

02 Lub luag haujlwm tseem ceeb ntawmconductive capacitor

Hauv kev tsim ntawm AC / DC converters, tso zis capacitor yog qhov tseem ceeb. Conductive capacitors tuaj yeem pab txo qhov ripple ntawm cov zis hluav taws xob thiab ua lub luag haujlwm tseem ceeb hauv kev lim dej hauv cov hluav taws xob hloov hluav taws xob. Thaum lub capacitor absorbs lub ripple tam sim no, nws yuav inevitably tsim ib tug ripple voltage. Hauv kev siv tswv yim, nws yog feem ntau yuav tsum tau hais tias lub hwj huam mov ripple tsis pub tshaj 1% ntawm kev khiav hauj lwm voltage ntawm cov khoom siv.

Yog tias siv GaN, ESR ntawm YMIN khoom-kua hybrid capacitors ruaj khov nyob rau hauv ntau yam ntawm 10KHz ~ 800KHz, uas tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm GAN high-frequency switching.

Yog li ntawd, nyob rau hauv AC / DC converters siv gallium nitride, conductive capacitors yog qhov zoo tshaj plaws tso zis capacitors.

03 YMIN sib phim nrog cov conductivity capacitor

Nrog rau kev txais yuav ntawm GaN, kev siv ntau zaus hloov AC / DC converters tau maj mam nce. Txhawm rau txuas ntxiv kom tau raws li cov kev xav tau ntawm cov neeg siv khoom hloov pauv, YMIN, raws li kev lag luam innovator hauv cov khoom siv hluav taws xob, siv nws cov cuab yeej ua haujlwm siab / kev ntseeg siab siab los coj cov neeg siv khoom tshiab, cov khoom lag luam dav dav (txog 100V) thiab zoo. kev pabcuam.

Peb cov khoom polymer khoom txhuas electrolytic capacitors, polymer khoom-kua hybrid txhuas electrolytic capacitors, multilayer polymer khoom txhuas electrolytic, thiab polymer tantalum capacitor series khoom tuaj yeem ua tau zoo nrog cov hloov tshiab AC / DC.

Cov khoom siv hluav taws xob no tau siv dav hauv 5-20V cov khoom siv dav siv hauv cov khoom siv pej xeem, 24V cov khoom siv rau kev lag luam, thiab 48V cov khoom siv sib txuas lus. Yuav kom daws tau qhov teeb meem tsis txaus nyob rau xyoo tas los no, kev ua haujlwm siab dua yog xav tau, thiab cov khoom lag luam hloov mus rau 48V nce ntxiv (automotive, cov chaw zov me nyuam, USB-PD, thiab lwm yam), ntxiv rau kev nthuav dav ntau yam ntawm GaN thiab conductive capacitor.

Nyob rau hauv lub sijhawm tshiab, YMIN ua raws li lub tswv yim kev pabcuam ntawm "Capacitor Solutions, Nug YMIN rau koj daim ntawv thov", tau txiav txim siab kom ua tiav cov kev xav tau tshiab thiab kev ua haujlwm tshiab los ntawm cov ntawv thov tshiab thiab cov kev daws teeb meem tshiab, thiab nquag tshawb nrhiav qhov kev cia siab ntawm miniaturization ntawm AC / DC. converters nyob rau hauv daim ntawv thov GaN. YMIN hais kom tsom mus rau kev tsim cov khoom tshiab, kev tsim khoom siab thiab kev thov-kawg tshaj tawm, muab cov neeg siv khoom nrog cov khoom siv hluav taws xob zoo, muab cov kev pabcuam tshiab thiab zoo, nce kev tshawb fawb peev, thiab txhawb kev lag luam kev vam meej.
