Kodi mukudziwa kuti PD ndi chiyani?Dzina lonse la PD ndi Power Delivery, yomwe ndi ndondomeko yoyendetsera yogwirizana yopangidwa ndi USB Association kuti igwirizane ndi zolumikizira kudzera pa USB Type C. Moyenera, malinga ngati chipangizochi chikuthandizira PD, mosasamala kanthu kuti ndinu kope, piritsi kapena foni yam'manja. , mutha kugwiritsa ntchito njira yolipirira imodzi.Chingwe cha USB TypeC kupita ku TypeC ndi chojambulira cha PD chimagwiritsidwa ntchito kulipira.
1.Basic Concept of Charging
Kuti timvetse PD poyamba, choyamba tiyenera kumvetsetsa kuti kuthamanga kwachangu kumayenderana ndi mphamvu zowonjezera, ndipo mphamvu imagwirizana ndi magetsi ndi magetsi, ndipo izi zimagwirizanitsidwa ndi njira yamagetsi.
P= V*ine
Chifukwa chake ngati mukufuna kulipira mwachangu, mphamvuyo iyenera kukhala yayikulu.Kuti muwonjezere mphamvu, mukhoza kuwonjezera mphamvu, kapena mukhoza kuwonjezera mphamvuyi.Koma pasanakhale PD chojambulira protocol, yotchuka kwambiriUSB 2.0muyezo umanena kuti voteji iyenera kukhala 5V, ndipo yapano ndi 1.5A kwambiri.
Ndipo zamakono zidzachepetsedwa ndi khalidwe la chingwe cholipiritsa, kotero kumayambiriro kwa chitukuko cha kuthamanga mofulumira, cholinga chachikulu ndikuwonjezera magetsi.Izi zimagwirizana ndi mayendedwe ambiri opatsirana.Komabe, popeza panalibe njira yolipirira yolumikizana panthawiyo, opanga osiyanasiyana adapanga ma protocol awoawo, kotero USB Association idayambitsa Power Delivery kuti igwirizanitse protocol yolipira.
Power Delivery ndi yamphamvu kwambiri chifukwa sikuti imangothandizira kuthamangitsa zida zotsika mphamvu, komanso imathandizira kulipiritsa zida zamphamvu kwambiri monga zolembera.Ndiye tiyeni tiphunzire za PD protocol!
2.Chiyambi cha kupereka mphamvu
Pakhala pali mitundu itatu ya PD mpaka pano, PD / PD2.0 / PD3.0, yomwe PD2.0 ndi PD3.0 ndizofala kwambiri.PD imapereka magawo osiyanasiyana a mbiri malinga ndi kugwiritsa ntchito mphamvu mosiyanasiyana, ndipo imathandizira zida zingapo A,kuchokera ku mafoni am'manja, ku mapiritsi, ku laputopu.
PD2.0 imapereka mitundu yosiyanasiyana yamagetsi ndi magetsi kuti ikwaniritse zofunikira zamagetsi pazida zosiyanasiyana.
PD2.0 ili ndi chofunikira, ndiko kuti, protocol ya PD imangothandizira kulipira kudzera pa USB-C, chifukwa protocol ya PD imafuna mapini apadera mu USB-C kuti mulumikizane, kotero ngati mukufuna kugwiritsa ntchito PD kulipira, osati chojambulira chokha. ndi Kuti muthandizire protocol ya PD, chipangizo cholumikizira chiyenera kulingidwa kudzera pa USB-C kudzera pa chingwe cha USB-C kupita ku USB-C.
Kwa zolembera, cholembera chogwira ntchito kwambiri chingafunike mphamvu ya 100W.Kenaka, kudzera mu protocol ya PD, bukhuli likhoza kugwiritsa ntchito mbiri ya 100W (20V 5A) kuchokera kumagetsi, ndipo magetsi adzapereka kope ndi 20V ndi kuchuluka kwa 5A.Magetsi.
Ngati foni yanu yam'manja ikufunika kulipiritsa, ndiye kuti foni yam'manja sifunikira mphamvu yamagetsi yamagetsi, chifukwa chake imagwiritsa ntchito mbiri ya 5V 3A yokhala ndi magetsi, ndipo magetsi amapereka foni yam'manja 5V, mpaka 3a.
Koma PD ndi mgwirizano wolumikizana.Mutha kupeza kuti chipangizo chamagetsi ndi magetsi omwe akugwiritsidwa ntchito pa mbiri inayake pakali pano, koma kwenikweni, magetsi sangathe kupereka madzi otere.Ngati magetsi alibe mphamvu yamagetsi, magetsi amayankha.Mbiriyi palibe pachipangizo cholumikizira, chonde perekani mbiri ina.
Chifukwa chake, PD ndi chilankhulo cholumikizirana pakati pa magetsi ndi chipangizo cholumikizira.Kupyolera mukulankhulana, njira yoyenera yoperekera magetsi imagwirizanitsidwa.Pomaliza, magetsi amatuluka ndipo terminal amavomereza.
3.Chidule - PD Protocol
Zomwe zili pamwambapa ndi "pafupifupi" kuyambika kwa protocol ya PD.Ngati simukuzimvetsa, zili bwino, nzabwinobwino.Muyenera kudziwa kuti PD protocol idzagwirizanitsa pang'onopang'ono ndondomeko yoyendetsera mtsogolo.Laputopu yanu imatha kulipiritsidwa mwachindunji kudzera pa charger ya PD ndi chingwe cha USB Type-C, monganso foni yanu yam'manja ndi kamera yanu.Mwachidule, simudzafunika kulipira mtsogolo.Mulu wa ma charger, mumangofunika charger imodzi ya PD.Komabe, sichaja cha PD chokha.Njira yonse yolipirira imaphatikizapo: chojambulira, chingwe cholipirira ndi terminal.Chojambulira sichiyenera kukhala ndi madzi okwanira, komanso chingwe cholipiritsa chiyenera kukhala ndi mphamvu zokwanira Kuthamanga kwambiri kuti mutengere chipangizo chanu, ndipo mwinamwake mutha kumvetsera kwambiri nthawi ina mukadzagula chojambulira.
