Dab tsi yog qhov txawv ntawm USB PD2.0, USB PD3.0 thiab USB PD3.1?

Dab tsi yog qhov txawv ntawm USB PD2.0, USB PD3.0 thiab USB PD3.1?

Txij li thaum nws pib pib, USB PD ceev them thev naus laus zis tau dhau los ua ntau yam tseem ceeb, los ntawm PD 2.0 mus rau PD 3.1 tam sim no, txhua qhov kev hloov kho tau muab kev paub zoo dua thiab kev nyab xeeb dua rau cov neeg siv. Kab lus no yuav muab cov lus qhia luv luv thiab sib piv ntawm peb hom USB PD them tus qauv.

USB PD 2.0, raws li kev tso tawm sai sai- tus qauv them nqi rau kev tsim khoom loj thiab kev siv lag luam, tsis yog tsuas yog xaiv USB Hom -C interface raws li qhov chaw nres nkoj tus qauv nkaus xwb tab sis kuj tseem txhim kho nws txoj haujlwm suav nrog kev them nyiaj, hloov pauv cov ntaub ntawv, thiab xa suab. PD 2.0 txhais cov kev them nyiaj tsis txaus txhawb nqa tawm ntawm 5V3A, 9V3A, 12V3A, 15V3A, thiab 20V5A, ua tiav lub zog them siab tshaj plaws ntawm 100W. Kev taw qhia ntawm tus qauv no tau tsim lub hauv paus rau kev sib koom ua ke ntawm USB PD ceev them nyiaj. Txawm hais tias lub lag luam xov tooj ntawm tes tseem tseem yog tus thawj tswj hwm ntawm tus tswv ceev ceev{18}} them cov txheej txheem xws li QC thiab AFC thaum lub sijhawm, PD them sai sai pib tau txais kev pom zoo hauv cov neeg siv khoom siv hluav taws xob nrog kev tso tawm ntawm New MacBook los ntawm Apple.

USB PD 3.0 yog qhov hloov kho dua tshiab ntawm PD 2.0. Piv nrog rau nws cov thawj, PD 3.0 tsis qhia txog cov kev hloov pauv tseem ceeb hauv kev them nyiaj tshwj xeeb, tseem txhawb nqa 5V3A, 9V3A, 12V3A, 15V3A, thiab 20V5A tso tawm nrog lub zog siab tshaj plaws ntawm 100W tsis hloov pauv. Nws qhov kev txhim kho tseem ceeb nyob hauv cov txheej txheem txheej txheem, suav nrog cov lus piav qhia ntxaws ntxiv ntawm kev tsim- hauv cov yam ntxwv roj teeb, ntxiv cov khoom siv software / hardware version txheeb xyuas thiab software hloov tshiab muaj peev xwm ntawm PD kev sib txuas lus, nrog rau kev koom ua ke ntawm daim ntawv pov thawj digital thiab kos npe digital. Cov kev txhim kho no ntxiv dag zog rau cov txheej txheem kev ruaj ntseg thiab kev sib cuam tshuam ntawm cov khoom siv, ua rau txoj hauv kev rau kev ua haujlwm PPS yav tom ntej. Txawm hais tias PD 3.0 tsis muaj qhov cuam tshuam hauv kev them nqi tshwj xeeb, nws tsim lub hauv paus tseem ceeb rau kev txhim kho cov txheej txheem ceev tom ntej{19}} them cov txheej txheem.

USB PD 3.1 yog qhov ceev tam sim no - tus qauv them nqi, sawv cev rau kev hloov kho tseem ceeb ntawm PD 3.0 PPS. Nws faib lub hwj chim rau hauv ob pawg: Tus Txheej Txheem Fais Fab (SPR) thiab Kev Siv Hluav Taws Xob Ntxiv (EPR). Lub SPR khaws cia 100W txwv ntawm PD 3.0 PPS, thaum EPR qhia peb qhov ntsuas hluav taws xob ruaj khov -28V, 36V, thiab 48V- nrog rau qhov tso zis ntau tshaj tam sim no ntawm 5A ib qib, ua kom muaj zog txog 240W tso zis. Tsis tas li ntawd, PD 3.1 suav nrog peb qhov hloov kho qhov hluav taws xob (AVS) nyob rau hauv EPR: 15V-28V 5A, 15V-36V 5A, thiab 15V-48V 5A, nrog rau qhov tsawg kawg nkaus voltage theem ntawm 0.1V rau kev txhim kho precision dua yav dhau los versions. Qhov kev tso tawm ntawm PD 3.1 qhia txog kev nthuav dav ntawm USB PD tus qauv them sai sai los ntawm cov neeg siv khoom siv hluav taws xob mus rau qhov kev thov dav dav, suav nrog cov saib, cov cuab yeej server, thiab kev ruaj ntseg PoE xa hluav taws xob, ntxiv kev paub txog lub zeem muag ntawm "txhua yam uas raug them."

Cov lus hauv qab no qhia txog kev sib piv.
