Cov Lus Cog Tseg ntawm EU IEC 62368-1: 2026 - YOTI Multi-Port GaN Travel Chargers Twb Tau Tsim Nyog Lawm
EU Ua Kom Muaj Kev Nyab Xeeb Rau Cov Chaw Them Nqi GaN Mus Ncig Ua Si Ntau Qhov Chaw - YOTI Twb Tau Hloov Kho Lawm
Thaum Lub Rau Hli 27, 2026, Lub Koom Haum Txheem Hluav Taws Xob (ESA Tebchaws Europe) tau tshaj tawm ib qho kev ceeb toom: IEC 62368-1: 2026 tshiab uas tau tso tawm qhia txog cov kev cai xeem tshwj xeeb rau cov khoom siv hluav taws xob ntau lub chaw nres nkoj GaN. Txij li Lub Ib Hlis 2027, txhua lub chargers xa tawm mus rau European Union yuav tsum dhau daim ntawv pov thawj tshiab ua ntej kev lis kev cai tshem tawm.
Peb qhov chaw tsom mus rau qhov chaw tshiab no yog qhov chaw uas cov qauv tsim ntau lub chaw nres nkoj GaN muaj kev phom sij tshaj plaws:
- Kev tiv thaiv hluav taws xob dynamic overload
- Kev laus ntev ntev kub
- Cov kev txwv ntawm cov hluav taws xob electromagnetic nruj dua
Rau cov hom lag luam thiab cov neeg faib khoom, lub sijhawm hloov pauv tsuas yog rau lub hlis xwb. Kev ncua sijhawm ntawm kev tsim qauv lossis rov ua daim ntawv pov thawj dua tuaj yeem txhais tau tias Q1 cov khoom yuav tag lossis muaj kev pheej hmoo ntawm kev rov qab los.
YOTI, ua ib lub chaw tsim khoom R&D uas tsom mus rau GaN, tau pib ua ntej kev sib phim thaum lub sijhawm sau qauv ntawm tus qauv. Peb cov khoom siv ntau lub chaw nres nkoj GaN lub tshuab them nqi mus ncigs tau ua tiav kev tshuaj xyuas qhov sib txawv sab hauv raws li IEC 62368-1: 2026 thiab nkag mus rau hauv kev sim ua haujlwm sab nraud. Cov neeg siv khoom tuaj yeem ua raws li cov sijhawm xa khoom uas twb muaj lawm yam tsis muaj kev ntxhov siab txog kev tsim kho dua tshiab.
Yuav ua li cas YOTI daws txhua qhov kev xav tau tshiab
🔹 Kev Tiv Thaiv Kev Faib Fais Fab Dynamic Overload
Cov chaw them fais ntau lub qhov (multi-port chargers) ntsib teeb meem ib yam li no: thaum ib lub qhov khiav ntawm 65 W thiab lwm lub xav tau lub zog tag nrho los ntawm lub laptop, tag nrho cov zis yuav tshaj qhov ntsuas ntawm lub adapter. Tsab ntawv xyoo 2026 tam sim no yuam kom "dynamic load-sharing overload response" raug sim meej meej.
YOTI txoj kev daws teeb meem:
Cov txheej txheem PD tshwj xeeb nrog lub sijhawm tiag tiag Dynamic Power Management (DPM) algorithm - rov suav cov peev nyiaj fais fab thoob plaws ob lossis peb qhov chaw nres nkoj hauv milliseconds.
Cov qauv tau dhau los ua qhov txuas / tshem tawm cov voj voog sib law liag nyob rau hauv qhov kev hloov pauv tag nrho ntawm qhov kub qis yam tsis muaj ib qho OCP cuav.
Cov pwm uas twb muaj lawm tseem sib xws; MCU firmware hloov tshiab (OTA-muaj peev xwm) txaus kom ua tau raws li cov kev cai tshiab.
🔹 Kev Laus Ntev Ntev Kub Siab
GaN ntim 65 W txog 140 W rau hauv cov thawv me me, thawb qhov ceev ntawm thermal density 1.5-2 × siab dua li cov silicon ib txwm muaj. Tus qauv tshiab no ua kom nruj dua cov kev cai rau kev ruaj khov thermal thiab kev ua kom sov tom qab laus ntev.
YOTI txoj kev daws teeb meem:
Cov ntaub thaiv siv UL 94 V-0 rated PC + ABS nrog ntau qhov chaw ntsuas kub NTC.
Kev sim ua kom sov tau lees paub ntawm 1.2 × qhov ntsuas rau 8 teev kev laus tas mus li; qhov kub ntawm rooj plaub ntsuas nyob qis dua 62 ° C (txwv: 75 ° C).
Transformer barrier thiab creepage distances tsim nrog 20-30% margin ib IEC 62368-1: 2026 delta clauses-first-pass certification lav.
🔹 Kev txwv ntawm kev tawg hluav taws xob
Kev ua haujlwm ntau lub chaw nres nkoj tib lub sijhawm ua ke nrog kev hloov pauv GaN siab zaus tuaj yeem thawb cov pa phem tawm ze rau qhov txwv hauv 30-300 MHz band. Kev kho dua tshiab xyoo 2026 ua kom cov kev txwv no nruj dua.
YOTI txoj kev daws teeb meem:
6-txheej PCB + thawj sab tiv thaiv tuaj yeem + qhov zoo tshaj plaws Y-capacitor layout kom txo cov suab nrov hom sib xws ntawm qhov chaw.
Tag nrho cov kab khoom tau luam theej ua ntej raws li EN 55032 / CISPR 32 Class B nrog > [ ] dB margin.
Daim ntawv pov thawj CE + RED tuaj yeem muab sib xyaw ua ke, ua kom lub sijhawm luv luv mus rau kev ua lag luam.
Vim li cas ho xaiv YOTI rau koj qhov kev hloov pauv EU?
