Mazuva apfuura Xiaomi 12 Series' kutanga, Xiaomi inoenderera mberi kuburitsa zvakawanda nezve yavo nyowani mureza mutsara.
Kubva pakuburitswa kwechizvarwa chekutanga chekuchaja nekukurumidza neXiaomi muna 2019, kusvika kune yakanyanya kukurumidza kuchaja system paMIX 4, Wired kuchaja kumhanya yakawedzera ne 7.5 nguva uye Wireless kuchaja kumhanya yakawedzera ne 12 nguva. Iye zvino nemidziyo iripo pamusika, machaja anosanganisirwa anogona kuchaja zvizere mafoni mukati memaminitsi gumi nemashanu. Nekuwedzera uku kwekuchaja kumhanya uye kudzikira kwekuchaja nguva, smartphone user's tsika yekuchaja husiku Change to kuchaja panhunzi.
Kuti uwane kumhanya kukuru kwekuchaja, Xiaomi set kuripira nokukurumidza se yakakosha nzira yekutungamira muna 2019. Xiaomi yakatangwa mana akasiyana ekutsvagisa uye Development nzvimbo, Mumakore matatu Xioami akanyorera anopfuura 800 patents ndokusunungurwa mamiriyoni emidziyo akashongedzerwa neanokurumidza kuchaja masisitimu.
120W single cell solution yekuvandudza hupenyu hwebhatiri, kureruka uye hutete
Smartphones pamwe waya yekuchaja inomhanya kusvika ku120W shandisa dual-cell system pasina kunze. Mutengo wekumhanyisa kuchaja ndeye Kuderedza kushandiswa kwe nzvimbo yemukati zvefoni. The dual-cell bhatiri kana ichienzaniswa nesero rimwe bhatiri, huwandu hunenge % 3 kusvika% 4 yakaderera kupfuura sero rimwe chete, kutopfuura iro maviri-sero mabhatiri anoda imwe chip yekuchaja uye nekuda kwekuita uku kunozokonzera kutambisa %3 kusvika %4 yesimba. Single-cell bhatiri inogona kugadzirisa matambudziko aya asi anotarisana nea dambudziko guru kuwedzera simba rekuchaja pamusoro pe100W.
Chinangwa cheXiaomi ndechekuzadzisa yakanakisa chiyero pakati pehupenyu hwebhatiri uye kuita kwekuchaja uye kuwana single-cell 120W wired inokurumidza kuchaja.
Surge P1 uye iyo 120W imwe-sero inokurumidza kuchaja
Kare single-cell fast kuchaja mhinduro, kushandura 20V voltage kupinza kune mudziyo kuita 5V voltage, nhevedzano yedunhu rakafanana 5 dzakasiyana pombi dzekuchaja zvinodiwa. Nekuda kweizvi, curcuit inogadzira kupisa kwakawanda, ndizvo hazviiti kuchaja pa simba rakazara kwenguva refu uye zviri nyore zvakanyanya kuoma kuwana 120W kuripira nokukurumidza, zvinova zvisingagamuchiriki zve Xiaomi.
To redesign zvese kuchaja zvivakwa, zvakakosha kutsanangurazve basa rekukurumidza kuchaja chip. Iyo yakakosha yekuchaja yeXiaomi's 120W ndeye maviri akazvigadzira akangwara ekuchaja machipisi; inozivikanwa se Kuwedzera P1. Kuwedzera P1 inotora chimiro chakaoma chepombi yechinyakare 5 uye inoshandura iyo yakakwirira-voltage simba rekuisa kune nhare mbozha kuita yakakura ikozvino inogona kubhadhariswa zvakananga kubhatiri zvakanyanya.
Seyokutanga indasitiri yekuchaja chip, Kuwedzera P1 ane ultra-high efficient architecture. "Kushanda kweiyo resonant topology kwakakwira kusvika 97.5%, kugona kweiyo non-resonant topology ndeye 96.8%, uye kurasikirwa kwekupisa kunoderedzwa ne30%.
Kuwedzera P1 inoita basa rakawanda rekushandura: yechinyakare yekuchaja pombi voltage inoshandura inongoda maviri mamodhi ekushanda (shanduko, pfuura-kupfuura), nepo Kuwedzera P1 inoda kutsigira 1:1, 2:1 uye 4:1 maconversion modes, uye modhi dzose dzinoda kutsigira dual conduction, zvinoreva kuti 15 permutations uye misanganiswa yemode switching control, kanomwe kudarika yechinyakare pombi voltage converters. The 1:1 modhi inoita kuti skrini pakuchaja ishande zvakanyanya, iyo 2:1 modhi inowirirana nemamwe machaja uye 4:1 inodiwa 120W kuchaja. Reverse 1:4 na1:2 modhi tsigira high-power reverse kuchaja.
4: 1 yekuchaja chip ine yakanyanya kuchaja kunyatsoshanda uye yakanyanya kuoma dhizaini
Panguva imwe, Kuwedzera P1 iri zvakare 4: 1 yekuchaja chip ne Kuchaja kwakanyanya kubva kuXiaomi, iyo inogona kubudirira ultra-high simba density ye0.83W/mm², LDMOS inosvikawo iyo indasitiri-inotungamira yakanyanya-yakaderera 1.18mΩmm² RSP. The Kuwedzera P1 chip inoda matatu akasiyana FLY capacitor ane akasiyana voltage kuramba. imwe neimwe capacitor inoda yakazvimiririra ipfupi yedziviriro yedunhu uye yega yega inoshanda modhi inoda kunyatso kudzora precharge voltage, huwandu hwemachubhu emagetsi ari padyo nemapombi maviri echinyakare ekuchajisa, uye nekuda kwekuwedzera kwekugadzirwa kwetopology uye kuoma kwekushanda, imwe neimwe. Kuwedzera P1 inoda kupfuura kupfuura 2500 miedzo isati yabuda mufekitari, zvinova zvikuru kwazvo kupfuura pombi dzechaji yechinyakare.
mhedziso
Pakupedzisira, pamwe Surge P1 chipRubatsiro, Xiaomi inokwanisa kurerutsa dunhu rekuchaja uye panguva imwe chete iyo ultra-high kunyatsoshanda of Kuwedzera P1 zvinoreva kuti kupisa kwekugadzira kuchave kushoma uye kuzara kwemagetsi kuchaja kunogona kuenderera kwenguva yakareba.
Zvichauya xiaomi 12 pro ndiro yekutanga smartphone kubva kuXiaomi kuve yakagadzirirwa neSurge P1. Inotsigira 120W waya kuchaja, 50W isina waya kuchaja uye 10W kumashure Wireless kuchaja.
Muindasitiri yekukurumidza kuchaja, Xiaomi iri pamberi pevamwe vagadziri, vachishandisa kuzvigadzirira kuchaja machipisi. Tichaziva zvakawanda nezvazvo Kuwedzera P1 uye kugona kwayo pa December 28!
