Unoziva here kuti PD chii?Zita rakazara rePD ndiro Power Delivery, inova yakabatana yekuchaja protocol yakagadzirwa ne USB Association kuti ibatanidze zvibatanidza kuburikidza ne USB Type C. Zvakanaka, chero bedzi mudziyo uchitsigira PD, zvisinei kuti uri kabhuku, piritsi kana nhare mbozha. , unogona kushandisa imwechete yekuchaja protocol.A USB TypeC kune TypeC tambo uye PD charger inoshandiswa kuchaja.
1.Basic Concept yekuchaja
Kuti tinzwisise PD kutanga, tinofanira kutanga tanzwisisa kuti kumhanya kwekuchaja kune chekuita nemagetsi ekuchaja, uye simba rine chekuita nevolti uye yazvino, uye izvi zvakabatana nemagetsi formula.
P= V*I
Saka kana iwe uchida kuchaja nekukurumidza, simba rinofanira kunge rakakwirira.Kuti uwedzere simba, unogona kuwedzera voltage, kana iwe unogona kuwedzera ikozvino.Asi kusati kwave pasina PD yekuchaja protocol, inonyanya kufarirwaUSB2.0chiyero chinotsanangura kuti voltage inofanira kunge iri 5V, uye ikozvino inongova 1.5A zvakanyanya.
Uye iyo yazvino ichaganhurwa nemhando yetambo yekuchaja, saka mudanho rekutanga rekuvandudza kwekuchaja nekukurumidza, chinangwa chikuru ndechekuwedzera voltage.Izvi zvinofambirana netambo zhinji dzekutumira.Nekudaro, sezvo pakanga pasina yakabatana yekuchaja protocol panguva iyoyo, vagadziri vakasiyana vakagadzira yavo yekuchaja mapuroteni, saka USB Association yakatanga Power Delivery kubatanidza iyo yekuchaja protocol.
Power Delivery ine simba rakawanda pakuti haingotsigire kushoma-simba kuchaja kwemidziyo, asiwo inotsigira kuchaja kwemidziyo ine simba repamusoro senge mabhuku ekunyorera.Zvadaro ngatidzidzei nezve PD protocol!
2.Introduction kune simba rekupa
Pave nemhando nhatu dzePD kusvika parizvino, PD / PD2.0 / PD3.0, pakati peiyo PD2.0 uye PD3.0 ndiyo inonyanya kuzivikanwa.PD inopa akasiyana mazinga emaprofile zvinoenderana neyakasiyana mashandisiro emagetsi, uye inotsigira akawanda A akasiyana emidziyo,kubva kunharembozha, kumatablet, kumalaptops.
PD2.0 inopa akasiyana-siyana emagetsi uye azvino musanganiswa kuti asangane nezvinodiwa zvemagetsi ezvishandiso zvakasiyana.
Iyo PD2.0 ine chinodiwa, ndiko kuti, iyo PD protocol inongotsigira kuchaja kuburikidza ne USB-C, nekuti iyo PD protocol inoda chaiwo mapini mu USB-C yekutaurirana, saka kana iwe uchida kushandisa PD kuchaja, kwete chete charger. uye Kuti utsigire PD protocol, mudziyo wekupedzisira unofanirwa kuchajwa kuburikidza ne USB-C kuburikidza ne USB-C kuenda ku USB-C yekuchaja tambo.
Kune mabhuku ekunyorera, kabhuku kadiki-rinoita basa repamusoro rinogona kuda 100W magetsi.Zvadaro, kuburikidza nePD protocol, bhuku rekunyora rinogona kushanda kune 100W (20V 5A) purogiramu kubva kune magetsi, uye magetsi achapa bhuku racho ne20V uye yakawanda ye5A.Magetsi.
Kana nharembozha yako ichida kubhadhariswa, saka nhare mbozha haidi simba rakawanda rekugezera, saka rinoshanda kune 5V 3A mbiri ine simba rekupa, uye magetsi anopa nharembozha 5V, kusvika ku3a.
Asi PD ingori chibvumirano chekukurukurirana.Iwe unogona kuona kuti iyo terminal mudziyo uye magetsi anoiswa kune imwe chimiro izvozvi, asi kutaura zvazviri, magetsi anogona kusakwanisa kupa yakakwira wattage.Kana magetsi asina simba rakadaro rakakwirira, magetsi anopindura.Iyi mbiri haisi kuwanikwa kune terminal mudziyo, ndapota ipa imwe mbiri.
Saka muchokwadi, PD mutauro wekutaurirana pakati pemagetsi uye mudziyo wekupedzisira.Kuburikidza nekukurukurirana, mhinduro yemagetsi yakakodzera inobatanidzwa.Pakupedzisira, magetsi anobuda uye iyo terminal inoigamuchira.
3.Summary - PD Protocol
Izvo zviri pamusoro ndiyo "inofungidzira" sumo yePD protocol.Kana iwe usingazvinzwisise, zvakanaka, zvinowanzoitika.Iwe unongoda kuziva kuti iyo PD protocol inozobatanidza zvishoma nezvishoma iyo yekuchaja protocol mune ramangwana.Laptop yako inogona kubhadhariswa zvakananga kuburikidza nePD charger uye USB Type-C yekuchaja tambo, sezvazvichaita mbozhanhare yako nekamera yako.Muchidimbu, hauzodi kubhadharisa mune ramangwana.Boka remajaja, iwe unongoda imwe PD charger.Nekudaro, haisi PD charger chete.Iyo yese yekuchaja maitiro inosanganisira: charger, tambo yekuchaja uye terminal.Iyo charger haifanire kunge iine yakaringana yekubuda wattage, asiwo tambo yekuchaja inofanirwa kunge iine huwandu hwakakwana kune Iyo inokurumidza kukurumidza kuchaja mudziyo wako, uye pamwe unogona kubhadhara zvakanyanya nguva inotevera paunotenga charger.
