USB Fais Fab Xa Khoom Siv Ceev Them System
Kev siv thev naus laus zis yog ib qho uas txuas ntxiv mus sai sai hauv lub caij nyoog niaj hnub no. Ib qho ntawm cov qauv tshiab tshaj plaws hauv cov khoom siv hluav taws xob yog kev them ceev, uas lub hom phiaj yog kom txo lub sijhawm uas yuav tsum tau them rov qab rau cov khoom siv hluav taws xob. Ib qho qauv tseem ceeb hauv pawg no yog USB Power Delivery (USB PD). Tsab xov xwm no yuav tham txog qhov system them ceev raws li USB Power Delivery, suav nrog nws ua haujlwm li cas, nws cov txiaj ntsig, kev siv, thiab qhov cuam tshuam yav tom ntej.
Kev Taw Qhia Txog USB Power Delivery
USB Power Delivery yog ib tus qauv tsim los txhim kho kev them thiab xa cov ntaub ntawv hla cov cables USB. USB PD tso cai rau cov khoom siv them ntawm cov hluav taws xob thiab cov hluav taws xob siab dua li cov qauv USB yav dhau los.
Keeb Kwm ntawm USB Fais Fab Xa Khoom
Txij li thaum nws thawj zaug qhia tawm xyoo 1996, tus qauv USB tau hloov kho ntau yam. USB Power Delivery pib tau txais kev saib xyuas thaum nws tau qhia tawm ua ib feem ntawm USB 3.1 specification hauv xyoo 2012. Tus qauv USB 3.1 tso cai rau kev xa hluav taws xob txog li 100 watts, uas yog qhov sib txawv tseem ceeb ntawm cov qauv yav dhau los uas tsuas tuaj yeem tswj tau txog li 2,5 watts (ntawm USB 2.0) lossis 4,5 watts (ntawm USB 3.0).
Xyoo 2014, cov lus qhia USB PD tau raug kho dua tshiab thiab hloov kho tshiab ua ib feem ntawm tus qauv USB Type-C uas xav tias yuav dhau los ua kev daws teeb meem thoob ntiaj teb rau kev them cov khoom siv hluav taws xob xws li xov tooj ntse, ntsiav tshuaj, thiab laptops.
Kev Xa Khoom Fais Fab USB Ua Haujlwm Li Cas
USB Power Delivery ua haujlwm los ntawm kev tso cai rau cov khoom siv uas txhawb nqa nws sib tham thiab sib tham nrog ib leeg txog qhov lawv xav tau lossis tuaj yeem muab hluav taws xob ntau npaum li cas. Piv txwv li, thaum koj txuas lub xov tooj ntse uas siv USB PD rau lub charger uas siv USB PD, kev sib txuas lus ntawm ob lub khoom siv.
Qhov kev sib txuas lus no yog ua tiav los ntawm CC (Configuration Channel) pin ntawm USB Type-C port. Siv cov txheej txheem sib txuas lus no, lub cuab yeej yuav txiav txim siab qhov profile fais fab tsim nyog raws li qhov voltage thiab tam sim no uas lub charger tuaj yeem muab tau thiab qhov xav tau ntawm lub cuab yeej uas raug them.
Cov Ntaub Ntawv Fais Fab hauv USB PD
Ib qho ntawm cov yam zoo siab tshaj plaws ntawm USB Power Delivery yog qhov yooj ywm uas nws muaj nyob rau hauv cov qauv fais fab. Tus qauv no tso cai rau ntau yam qauv fais fab siv tau:
– 5V @ 2A (10W)
– 9V @ 3A (27W)
– 15V @ 3A (45W)
– 20V @ 5A (100W)
Nrog rau ntau yam kev siv fais fab no, USB PD tsis yog tsuas yog kev daws teeb meem rau cov khoom siv me me xws li smartphones thiab ntsiav tshuaj xwb, tab sis kuj tseem siv tau los them cov laptops lossis cov khoom siv uas xav tau fais fab ntau dua.
Theem Kev Sib Tham
Thaum lub sijhawm sib tham, lub cuab yeej uas raug them yuav thov fais fab los ntawm lub charger raws li cov profiles muaj. Lub charger, ces, yuav teb thiab muab fais fab raws li qhov kev thov. Cov txheej txheem no yog ua haujlwm tsis siv neeg thiab siv sijhawm me ntsis, feem ntau tsuas yog ob peb feeb xwb.
Cov txiaj ntsig ntawm kev xa hluav taws xob USB
Nrog rau kev siv cov khoom siv nqa tau ntau zuj zus, qhov xav tau kev them ceev thiab ua haujlwm tau zoo tau dhau los ua qhov tseem ceeb dua. Nov yog qee qhov txiaj ntsig tseem ceeb ntawm USB Power Delivery:
Kev Them Nqi Sai Dua
Ib qho ntawm cov txiaj ntsig loj tshaj plaws ntawm USB PD yog nws lub peev xwm them cov khoom siv sai heev. Nrog rau lub zog tso zis txog li 100 watts, lub sijhawm them tuaj yeem txo qis dua piv rau cov thev naus laus zis them nyiaj ib txwm muaj.
Kev Ywj Pheej Siab
USB PD yog tsim los kom yooj ywm thiab siv tau ntau yam. Nws siv tau los them ntau yam khoom siv ntawm ntau qhov loj me thiab lub zog xav tau. Txij li cov xov tooj ntse mus rau cov laptops, USB PD tuaj yeem ua txhua yam.
Universal thiab Txheem
Vim tias USB PD yog ib feem ntawm USB Type-C specification, nws yuav tsum dhau los ua tus qauv thoob ntiaj teb rau kev them hluav taws xob. Qhov no txo qhov xav tau ntau lub xov hlau thiab cov chargers rau ntau yam khoom siv, txuag tau qhov chaw thiab nyiaj txiag.
Kev Siv Hluav Taws Xob Zoo
USB PD kuj tseem siv hluav taws xob tau zoo dua. Los ntawm kev txo lub sijhawm them thiab xyuas kom meej tias lub zog xa tuaj raws li qhov xav tau ntawm lub cuab yeej, USB PD pab txuag hluav taws xob thiab txo qhov pov tseg.
Kev Siv thiab Kev Siv
Thaum USB PD nrov zuj zus, ntau lub cuab yeej thiab cov chargers txhawb nqa tus qauv no pib tshwm sim hauv kev ua lag luam. Qee qhov piv txwv ntawm kev siv suav nrog:
Laptops thiab Ultrabooks
Ntau lub tuam txhab tsim laptop tam sim no muaj ib lub qhov (port) USB Type-C uas txhawb nqa USB PD ua lub qhov (port) them fais xwb. Qhov no tsis yog tsuas yog txo qhov kev siv cov chargers tshwj xeeb xwb tab sis kuj tso cai rau cov laptops kom them tau los ntawm lub hwj chim USB PD lossis lub charger phab ntsa.
Smartphone
Muaj ntau lub xov tooj ntse uas siv USB PD technology los them sai sai. Qhov no ua rau cov neeg siv them tau sai dua thiab yooj yim dua.
Cov Khoom Siv thiab Cov Txhab Nyiaj Fais Fab
Cov txhab nyiaj fais fab uas txhawb nqa USB PD tau dhau los ua ntau dua, muab kev daws teeb meem them nqi sai dua thiab ua haujlwm tau zoo dua rau ntau yam khoom siv.
Kev Cuam Tshuam Yav Tom Ntej
Vim muaj kev siv ntau zuj zus, USB Power Delivery yuav dhau los ua tus qauv rau kev them fais yav tom ntej. Qhov no yuav muaj ntau yam zoo:
Kev txo cov khib nyiab hluav taws xob
Los ntawm kev tshem tawm qhov xav tau ntau lub chargers thiab cov cables, USB PD muaj peev xwm txo tau cov e-pov tseg. Qhov no yog ib kauj ruam zoo rau kev siv thev naus laus zis uas tsis ua rau ib puag ncig puas tsuaj.
Kev sib xws thiab kev nplij siab
Siv ib tus qauv thoob ntiaj teb rau txhua yam khoom siv yuav ua rau cov neeg siv khoom yooj yim dua thiab sib xws. Tsis tas yuav nqa ntau lub chargers rau ntau yam khoom siv thaum mus ncig.
Kev Tsim Kho Tshiab thiab Kev Txhim Kho Ntxiv
Kev siv dav dav ntawm USB PD kuj tseem ua rau muaj kev tsim kho tshiab hauv kev siv roj teeb thiab kev them hluav taws xob. Cov chaw tsim khoom siv hluav taws xob yuav raug txhawb kom tsim cov khoom siv uas them tau sai dua thiab ua haujlwm tau zoo dua.
Xaus
Kev xa hluav taws xob USB tau hloov pauv txoj kev uas peb them peb cov khoom siv hluav taws xob. Nrog nws qhov kev ywj pheej, kev ua haujlwm zoo, thiab lub peev xwm xa hluav taws xob loj, tus qauv no tau dhau los ua qhov kev daws teeb meem thoob ntiaj teb uas peb xav tau heev. Thaum cov thev naus laus zis no tau txais kev siv dav dua, peb tuaj yeem cia siab tias yuav muaj cov khoom siv hluav taws xob ruaj khov dua, ua haujlwm tau zoo, thiab tsis ua rau ib puag ncig puas tsuaj yav tom ntej. Txawm tias koj yog tus siv xov tooj ntse lossis laptop, lub peev xwm them koj cov khoom siv sai dua thiab ua haujlwm tau zoo dua yog qhov zoo tseem ceeb uas yuav tsum tsis txhob saib tsis taus.
