Iintsuku ngaphambili Xiaomi 12 Series' Ukuqaliswa, i-Xiaomi iyaqhubeka nokutyhila ngakumbi malunga ne-flagship yabo entsha.
Ukusuka ekukhutshweni kwesizukulwana sokuqala sokutshaja ngokukhawuleza nguXiaomi ngo-2019, ukuya kwinkqubo yokutshaja ngokukhawuleza kwiMIX 4, Izantya zokutshaja ngeentambo inyuswe ngu amaxesha 7.5 kwaye i Izantya zokutshaja ezingenazingcingo inyuke nge amaxesha 12. Ngoku ngezixhobo zangoku kwimarike, iitshaja ezibandakanyiweyo zinokutshaja ngokupheleleyo iifowuni kwimizuzu eyi-15. Ngokunyuka kwezantya zokutshaja kunye nokuncipha kwexesha lokutshaja, i-smartphone yomsebenzisi umkhwa wokutshaja ngobusuku itshintshelwe kwi ukutshaja kwimpukane.
Ukuze kuzuzwe isantya esiphezulu sokutshaja, Xiaomi iseti ukukhawuleza ngokukhawuleza njenge indlela ebalulekileyo yobuchule ngo-2019. U-Xiaomi usekwe amaziko amane awohlukeneyo oPhando noPhuhliso, Kwiminyaka emithathu Xioami isicelo ngaphezulu kwama-800 amalungelo awodwa omenzi wechiza waze wakhululwa izigidi zezixhobo ixhotyiswe ngeenkqubo zokutshaja ngokukhawuleza.
120W isisombululo seseli enye ukuphucula ubomi bebhetri, ukukhanya kunye nokubhitya
Smartphones kunye Izantya zokutshaja ezinocingo ukuya kuthi ga kwi-120W ukusebenzisa inkqubo yeeseli ezimbini ngaphandle kokukhetha. Ixabiso lokutshaja ngesantya esiphezulu kuku nciphisa ukusetyenziswa kwe indawo yangaphakathi yefowuni. I ibhetri yeeseli ezimbini xa kuthelekiswa nebhetri yeseli enye, umthamo umalunga %3 ukuya%4 ngaphantsi kuneseli enye, nangaphezu kokuba iibhetri-ezimbini zidinga enye itshiphu yokutshaja kwaye ngenxa yolu buchule kuya kubangela inkcitho ye-%3 ukuya kwi-%4 yamandla. Ibhetri yeseli enye Ungalungisa ezi ngxaki kodwa ijongene a umngeni omkhulu ukwandisa amandla okutshaja ngaphezulu kwe-100W.
Injongo yeXiaomi kukufezekisa ibhalansi engcono phakathi kobomi bebhetri kunye nokusebenza kokutshaja kunye nokufezekisa Iseli enye 120W ngentambo ukutshaja ngokukhawuleza.
I-Surge P1 kunye ne-120W i-single-cell itshaja ngokukhawuleza
Mandulo Izisombululo zokutshaja ngokukhawuleza kweseli enye, ukuguqula igalelo lamandla ombane angama-20V kwisixhobo sibe ngumbane we-5V, uthotho lweesekethe ezihambelanayo Iimpompo zentlawulo ezi-5 ezahlukeneyo Iyafuneka. Ngenxa yoko, i-curcuit ivelisa ubushushu obuninzi, yi akunakwenzeka ukuhlawulisa nge amandla apheleleyo ixesha elide kwaye ilungile kunzima kakhulu ukufikelela kwi-120W ukukhawuleza ngokukhawuleza, oko ikukuthi ayamkelekanga yeXiaomi.
Ku Ukuhlaziywa kwakhona iyonke ukutshaja ulwakhiwo, kuyimfuneko ukuphinda uchaze umsebenzi we-chip yokutshaja ngokukhawuleza. Undoqo wokutshaja kwe-Xiaomi's 120W yi iitshiphusi ezimbini zokutshaja eziziphuhlileyo; yaziwa njenge Ukunyuka kwe-P1. Ukunyuka kwe-P1 ithatha isakhiwo esiyinkimbinkimbi sempompo yentlawulo ye-5 yendabuko kwaye iguqule igalelo lamandla aphezulu-voltage kwifowuni ephathekayo ibe ngumbane omkhulu onokuthi uhlawulwe ngokuthe ngqo kwibhetri ngokufanelekileyo.
Njengetshiphu yokuqala yokutshaja kwishishini, Ukunyuka kwe-P1 unayo uyilo olusebenzayo oluphezulu. "Ukusebenza kakuhle kwe-resonant topology kuphezulu ukuya kuma-97.5%, ukusebenza kwe-non-resonant topology yi-96.8%, kwaye ilahleko yobushushu iyancipha ngama-30%.
Ukunyuka kwe-P1 yenza umsebenzi omninzi woguqulo: umguquli wempom yentlawulo yemveli ifuna kuphela iindlela ezimbini zokusebenza (utshintsho, ukudlula), ngelixa Ukunyuka kwe-P1 idinga ukuxhasa i-1: 1, 2: 1 kunye ne-4: iindlela zokuguqulwa kwe-1, kwaye zonke iindlela zifuna ukuxhasa ukuqhutyelwa kabini, oku kuthetha ukuba i-permutations ye-15 iyonke kunye nendibaniselwano yokulawula ukuguqulwa kwemowudi, amaxesha angama-7 ngaphezu kwe-converter ye-voltage yempompo yentlawulo yendabuko. I 1:1 indlela yenza isikrini xa utshaja kakuhle ngakumbi, i 2:1 indlela iyahambelana neetshaja ezininzi kunye ne 4:1 iyafuneka I-120W ishaja. Umva 1:4 kunye 1:2 iindlela inkxaso ukutshaja okubuyela umva kwamandla aphezulu.
4:1 itshiphu yokutshaja eyona mpumelelo iphezulu yokutshaja kunye noyilo olunzima kakhulu
Ngaxeshanye, Ukunyuka kwe-P1 ikwayi-4:1 itshiphu yokutshaja nge ukutshaja ngokufanelekileyo ukusuka ku-Xiaomi, enokufikelela Uxinzelelo lwamandla aphezulu kakhulu ye-0.83W/mm², i-LDMOS nayo ifikelela kwi Ishishini elikhokelayo kakhulu 1.18mΩmm² RSP. I Ukunyuka kwe-P1 I-chip idinga i-FLY capacitors ezintathu ezahlukeneyo ezinokumelana nombane ohlukeneyo. i-capacitor nganye idinga isiphaluka esizimeleyo sokukhusela isiphaluka esizimeleyo kwaye imo yokusebenza nganye kufuneka ilawule ngokungqongqo i-voltage yokutshaja, inani leetyhubhu zamandla lisondele kwiimpompo ezimbini zentlawulo zemveli, kwaye ngenxa yokwanda koyilo lwe-topology kunye nobunzima obusebenzayo, nganye Ukunyuka kwe-P1 kufuneka kudlule ngaphezulu Iimvavanyo ezingama-2500 ngaphambi kokushiya umzi-mveliso, oko ikukuthi iphezulu kakhulu kuneempompo zentlawulo zemveli.
isiphelo
Ekugqibeleni, nge Itshiphu yeP1 yetshiphuUncedo, i-Xiaomi iyakwazi ukwenza lula isekethe yokutshaja kwaye kwangaxeshanye i Ukusebenza okuphezulu kakhulu of Ukunyuka kwe-P1 kuthetha ukuba ukuveliswa kobushushu kuya kuba ngaphantsi kwaye ukutshaja kwamandla apheleleyo kunokuqhubeka ixesha elide.
Ozayo xiaomi 12 pro Ingaba i i-smartphone yokuqala ukusuka Xiaomi ukuxhotyiswa ngeSurge P1. Ixhasa 120W iingcingo ukubiza, I-50W engenazingcingo ukutshaja kunye 10W umva wireless Ukutshaja.
Kwishishini lokutshaja ngokukhawuleza, uXiaomi uphambi kwabanye abavelisi, usebenzisa ukuziphuhlisa ukutshaja iitshiphusi. Siza kwazi ngakumbi malunga Ukunyuka kwe-P1 kunye nobuchule bayo Disemba 28!
