Uyazi ukuthi yini i-PD?Igama eligcwele le-PD elithi Power Delivery, okuyiphrothokholi yokushaja ehlanganisiwe eyakhiwe yiNhlangano ye-USB ukuze ihlanganise izixhumi nge-USB Type C. Okufanelekile, inqobo nje uma idivayisi isekela i-PD, kungakhathaliseki ukuthi uyincwajana, ithebhulethi noma iselula. , ungasebenzisa iphrothokholi yokushaja eyodwa.Ikhebula le-USB TypeC kuya ku-TypeC kanye neshaja ye-PD kusetshenziselwa ukushaja.
1.Umqondo Oyisisekelo Wokushaja
Ukuze siqonde i-PD kuqala, kufanele siqale siqonde ukuthi isivinini sokushaja sihlobene namandla okushaja, futhi amandla ahlobene ne-voltage ne-current, futhi lokhu kuxhunywe kufomula kagesi.
P= V*I
Ngakho-ke uma ufuna ukushaja ngokushesha, amandla kufanele abe phezulu.Ukwandisa amandla, ungakwazi ukwandisa i-voltage, noma ungakwazi ukwandisa okwamanje.Kepha ngaphambi kokuthi ingekho iphrothokholi yokushaja ye-PD, edume kakhuluI-USB2.0izinga licacisa ukuthi i-voltage kufanele ibe ngu-5V, futhi yamanje ingu-1.5A kakhulu.
Futhi yamanje izonqunyelwa izinga lekhebula lokushaja, ngakho-ke esigabeni sokuqala sokuthuthukiswa kokushaja okusheshayo, inhloso eyinhloko ukukhulisa i-voltage.Lokhu kuhambisana nezintambo eziningi zokudlulisela.Kodwa-ke, njengoba yayingekho iphrothokholi yokushaja ehlanganisiwe ngaleso sikhathi, abakhiqizi abahlukahlukene bazakhela ezabo izivumelwano zokushaja, ngakho Inhlangano ye-USB yethula ukulethwa kwamandla ukuze kuhlanganiswe umthetho olandelwayo wokushaja.
I-Power Delivery inamandla kakhulu ngoba ayisekeli nje kuphela ukushajwa kwamandla aphansi wamadivayisi, kodwa futhi isekela ukushajwa kwamadivayisi anamandla amakhulu njengezincwadi.Bese sifunde ngephrothokholi ye-PD!
2.Isingeniso sokulethwa kwamandla
Kube khona izinguqulo ezintathu ze-PD kuze kube manje, i-PD / PD2.0 / PD3.0, phakathi kwazo i-PD2.0 ne-PD3.0 ezivame kakhulu.I-PD ihlinzeka ngamazinga ahlukahlukene wamaphrofayili ngokuya ngokusetshenziswa kwamandla okuhlukile, futhi isekela amadivaysi amaningi Ahlukahlukene,kusuka kumakhalekhukhwini, kumathebulethi, kumalaptop.
I-PD2.0 ihlinzeka ngezinhlobonhlobo zamandla kagesi nezinhlanganisela zamanje ukuze kuhlangatshezwane nezidingo zamandla zamadivayisi ahlukahlukene.
I-PD2.0 inesidingo, okungukuthi, umthetho olandelwayo we-PD usekela kuphela ukushaja nge-USB-C, ngoba umthetho olandelwayo we-PD udinga izikhonkwane ezithile ku-USB-C ukuze uxhumane, ngakho-ke uma ufuna ukusebenzisa i-PD ukushaja, hhayi ishaja kuphela. kanye nethi Ukuze usekele iphrothokholi ye-PD, idivayisi yetheminali idinga ukushajwa nge-USB-C ngentambo yokushaja ye-USB-C iye ku-USB-C.
Kuma-notebook, incwadi yokubhalela esebenza kahle kakhulu ingase idinge ukunikezwa kwamandla ka-100W.Khona-ke, ngephrothokholi ye-PD, i-notebook ingafaka isicelo sephrofayela ye-100W (20V 5A) kusukela ekunikezeni amandla, futhi ukunikezwa kwamandla kuzohlinzeka nge-notebook nge-20V kanye nobukhulu obungu-5A.Ugesi.
Uma ifoni yakho ephathekayo idinga ukushajwa, khona-ke ifoni ephathekayo ayidingi ukunikezwa kwamandla kagesi aphezulu, ngakho-ke ifaka iphrofayili ye-5V 3A ngokunikezwa kwamandla, futhi ukunikezwa kwamandla kunikeza iselula i-5V, kuze kufike ku-3a.
Kodwa i-PD iyisivumelwano sokuxhumana kuphela.Ungathola ukuthi idivayisi yetheminali namandla asetshenziswayo kuphrofayela ethile njengamanje, kodwa empeleni, ukunikezwa kwamandla kungase kungakwazi ukunikeza amanzi aphezulu kangaka.Uma ukunikezwa kwamandla kungenakho ukuphuma kwamandla aphezulu, ukunikezwa kwamandla kuzophendula.Le phrofayela ayitholakali kudivayisi yetheminali, sicela unikeze enye iphrofayela.
Ngakho-ke, i-PD iwulimi lokuxhumana phakathi kokunikezwa kwamandla kanye nedivayisi yokugcina.Ngokuxhumana, isixazululo esifanelekile sokuphakelwa kwamandla siyahlanganiswa.Ekugcineni, ukunikezwa kwamandla kuyaphuma futhi itheminali iyakwamukela.
3.Isifinyezo - Iphrothokholi ye-PD
Okungenhla yisingeniso "esilinganiselwe" sephrothokholi ye-PD.Uma ungakuqondi, kulungile, kujwayelekile.Udinga ukwazi kuphela ukuthi umthetho olandelwayo we-PD uzohlanganisa kancane kancane umthetho olandelwayo wokushaja ngokuzayo.Ikhompuyutha ephathekayo yakho ephathekayo ingashajwa ngokuqondile ngeshaja ye-PD kanye nekhebuli yokushaja ye-USB Type-C, njengoba kuzoba njalo neselula yakho nekhamera yakho.Ngamafuphi, ngeke udinge ukukhokhisa esikhathini esizayo.Inqwaba yamashaja, udinga ishaja ye-PD eyodwa kuphela.Nokho, akuyona nje ishaja ye-PD.Yonke inqubo yokushaja ibandakanya: ishaja, ikhebula lokushaja kanye netheminali.Ishaja akumele ibe namandla okukhipha okwanele kuphela, kodwa futhi ikhebula lokushaja kufanele libe nomthamo owanele ukuze Isivinini esisheshayo sokushaja idivayisi yakho ngokugcwele, futhi mhlawumbe unganaka kakhulu ngokuzayo uma uthenga ishaja.
