2 intambo yamandla ephina nge-VDE Uhlolojikelele lwesitifiketi
2 intambo yamandla ephina ngesitifiketi se-VDEyaziwa ngokusebenza kwayo okuhle kakhulu.Ipulaki yentambo yamandla yephinikhodi engu-2 imakwe ngekhodi yombala enemininingwane eminingi.Ikakhulukazi, okubomvu kungu-+5 V, okuphuzi kungu-+12 V, okumnyama kuyintambo "epholile" (Ground).
Ngaphezu kwalokho, ungasebenzisa le phinikhodi ukuze uxhume abalandeli bokupholisa abengeziwe namanye amadivaysi afana namakhadi ezithombe.Ibhodi lomama: Imvamisa ihlanganisa izikhonkwane ezingama-20-24 kuye ngebhodi lakho lomama.Enye inguqulo yale pulaki izikhonkwane ezingu-20+4 (ukumatanisa amaphini angu-20 nesixhumi samaphini angu-4 ndawonye.
2 intambo yamandla ephina ngesitifiketi se-VDEisebenzisa izixhumi zamandla namapulaki.Isixhumi samandla seyunithi yokucubungula emaphakathi (CPU) (+12V isixhumi samandla: Kunezinhlobo ezimbili; amaphini amane namaphini ayisishiyagalombili (imvamisa amaphini amane, imithombo emisha edizayinelwe amabhodi omama amadala). emisha ukusebenzisa izikhonkwane eziyisishiyagalombili. Izinhlobo zamapulagi ziyizi :
1. Ngakho Plug for hard drive, optical drive (ATA interface) (Peripheral connector): Kuhlanganisa 4 pin.
2. Ipulaki ye-floppy drive: Ifaka amaphinikhodi angu-4.
3. Ipulaki ye-hard drive, i-optical drive ene-SATA interface: Ihlanganisa izintambo ezi-4.
4. Amapulagi wamakhadi ezithombe ezisezingeni eliphezulu: Kuhlanganisa nezikhonkwane eziyisi-6.
Ezinye izici okufanele uzazi uma usebenzisa intambo yamandla yamaphini angu-2
Okulandelayo ezinye zezici;okumele bahlanganyele kukho2 intambo yamandla ephina ngesitifiketi se-VDE
Isikhathi sokulinda
Inani le-Holdup Time lichaza ukuthi isikhathi esingakanani, kuma-millisecond, intambo yamandla yezikhonkwane ezi-2 ingagcina imigqa yokukhipha elinganiselwe lapho amandla okokufaka enqanyulwa (isb, ukwehluleka kwamandla).Ngokufanayo, lokhu kuwusizo kakhulu ikakhulukazi uma uhlala endaweni enogesi ongaqinile
(Isibonelo, uma kwenzeka amandla akhanya ngokuzumayo bese ebuya, ikhompuyutha isengasebenza ngokujwayelekile).Inani lesikhathi Lokubamba lezinga le-ATX lingu-17ms futhi intambo yamandla yephinikhodi yekhompuyutha engu-2 kufanele ibe nale nkomba phezulu ngangokunokwenzeka.
I-Power Factor Correction (PFC) entanjeni yamandla yezikhonkwane ezi-2 nesitifiketi se-VDE
I-PFC ivumela intambo yamandla yamaphini angu-2 ukuthi isebenze kahle kakhulu.Kunezinhlobo ezimbili eziyinhloko zama-PFC: I-PFC esebenzayo kanye ne-Passive PFC.Ngaphezu kwalokho, abahlinzeki banezinhlobo ezimbili.I-PFC esebenzayo inohlobo olusebenza kahle kakhulu.Isebenzisa i-auto-tuning circuit ukuze ukusebenza kahle kukagesi kufinyelele ku-95% (ngokwethiyori).
Ngaphezu kwalokho, i-Active PFC iyakwazi futhi ukukhansela umsindo nokuqondisa intambo kagesi (okukuvumela ukuthi uxhume kunoma iyiphi indawo evamile engu-110V ukuya ku-220V ngaphandle kokukhathazeka ngezinkomba).Kodwa-ke, ngenxa yezakhiwo eziyinkimbinkimbi ze-Active PFC, izinto zikagesi ezisebenzisa lobu buchwepheshe zibiza kakhulu.
Izimpahla zamandla e-PFC;Iyasebenza futhi I-Passive
Ku2 intambo yamandla ephina ngesitifiketi se-VDE;Izimpahla zikagesi ze-PFC zisetshenziselwa ukwandisa amandla factor.Amanye amandla kagesi e-Active PFC asavumela umsebenzisi ukuthi asebenzise iswishi enquma amandla okokufaka.I-Passive PFC: Lolu uhlobo oluvame kakhulu namuhla.Ngokungafani ne-Active PFC, i-Passive PFC iqondanisa okwamanje ngama-capacitor okuhlunga ngakho-ke amandla ayo okusebenza azoshintshwa ngokuhamba kwesikhathi.
Ngaphezu kwalokho, izothonywa yizici zangaphandle ezifana nezinga lokushisa, ukushaqeka.Izimpahla zamandla zisebenzisa ubuchwepheshe be-Passive PFC zidinga ukuthi umsebenzisi alungise i-voltage yokufaka esebenzisa iswishi encane.Imithombo ye-Passive PFC ishibhile kunemithombo ye-PFC esebenzayo.
Imbiza Eshintshekayo ngaphansi kwentambo yamandla yezikhonkwane ezi-2 nesitifiketi se-VDE
Ezinye izinto ezinhle zikagesi ziza nama-potentiometer amancane ngaphakathi ukuze kulungiswe ama-voltage ezintambo zikagesi.Eqinisweni, uma intambo yakho yamandla engu-12V yehla ngaphansi kuka-11.5V, izodala ukungazinzi kulo lonke uhlelo.Khumbula ukuthi izinga le-ATX livumela i-voltage ngomugqa ngamunye ukuthi iguquguquke.
Nokho, lesi isici esithuthukisiwe futhi kufanele senziwe kuphela uma wazi ukuthi wenzani.Eminye imikhiqizo yamandla iwashintsha ngokuphelele lawa ma-potentiometer ukuze abasebenzisi bashintshe ngokukhululekile, njengochungechunge lwe-Antec's True Control.
Imodi yamandla athambile kanye ne-5V.Isignali yokulinda
I-Soft Power yindlela intambo yamandla yephinikhodi engu-2 evulwa ngayo noma ivalwe ngayo, kodwa esikhundleni sokusebenzisa iswishi eqinile njengezinga le-AT elidala, iyasebenza lapho i-BMC iyalela intambo yamandla yamaphini angu-2.2 intambo yamandla ephina ngesitifiketi se-VDEisetshenziswa kakhulu kumadivayisi afana namawashi, amarediyo, neshaja yamabhethri.
Ungakwazi ukuqinisekisa lokhu kalula ngokukwazi ukuvala isistimu yokusebenza ye-Windows noma uvule ikhompuyutha kusukela kukhibhodi negundane.Umthetho oyinhloko wokuthi i-BMC iyale intambo yamandla yamaphini angu-2 iwukusebenzisa isignali yokulinda yomugqa wokulinda +5V.
Ulayini wamandla nezinhlobo zawo
Le ntambo yamandla izimele ngokuphelele kwezinye izifunzo zemishini futhi izoba nesiginali noma nini lapho uxhuma amandla, amanye ama-BMC amasha avame ukuba nesibani sesignali ukukhombisa +5 V isimo sokulinda.Ngaphezu kwalokho, zimbalwa ezinye izintambo zamandla ezisizayo ohlelweni lwekhompyutha, okuhlanganisa:
I-inductive line +3.3V (+3.3V Sense): Umsebenzi oyinhloko ukuqapha i-voltage yolayini we-+3.3V ukuze uphakele i-BMC.Intambo yamandla ephinikhodi engu-2 ingaqondanisa okwamanje ngokunembile.
I-fan isebenza kanjani ngokuya nge-voltage?
Lapho i-voltage yalo mugqa yehla ngaphansi kwe-1 V, ifeni izocisha ngokuzenzakalelayo.Uma inani elingaphezu kuka-10.5 V lifinyelelwa, ifeni izosebenza ngomthamo ogcwele.Umsebenzi oyinhloko walo mklamo ukuvumela isistimu ukuthi ivale ifeni.
I-Fan Monitor (I-Fan Monitor): Lona umngane wesici sokulawula abalandeli;ivumela ukuqapha isivinini sokujikeleza kwabalandeli ohlelweni.Umsebenzi wayo oyinhloko ukuxwayisa abasebenzisi lapho ifeni yokupholisa ethile ingasebenzi kahle futhi iyeka ukusebenza.
Izinto eziyisisekelo zentambo yamandla yekhompuyutha engu-2 enhle
Ukuzinza kwe-voltage ephumayo: I-voltage ayichezuki ngaphezu kuka -5 ukuya ku-+5% ku-voltage elinganiselwe (ekhonjiswe entanjeni yamandla yezikhonkwane ezi-2 ) lapho umthombo usebenza kumthamo wawo wokuklama.
I-voltage ephumayo iphansi, ngaphandle kokuphazamiseka.
Ukusebenza kahle okuphezulu, okufinyelela ngaphezu kwama-80% (amandla okukhiphayo/okokufaka afinyelela > 80%)
2 intambo yamandla ephina ngesitifiketi se-VDEungasebenzisi amandla kazibuthe, izindawo zikagesi, ukuphazamiseka kwezinye izingxenye ezizungezile futhi kufanele zimelane nezinkundla kazibuthe, izindawo zikagesi, ukuphazamiseka kwezinye izinto ezizungezile eziwuthintayo.
Ngesikhathi sokusebenza, izintambo zamandla eziphinikhodi ezi-2 zenza ukushisa okuncane, futhi umsindo mncane.
Izintambo eziphumayo zihlukahlukene, zinamaphini amaningi ajwayelekile, asongwe kahle futhi aphikisana nokuphazamiseka.
Qinisekisa ukusebenza okuzinzile ngomthamo wokuklama isikhathi eside sokusebenza.
Qaphela: Into eyodwa okufanele uyiqaphele ukuthi amandla ajwayelekile kufanele abe nezitembu zesitifiketi sekhwalithi, kanye nemingcele efana nomthamo wamandla, i-voltage, njll.
Ungayithenga kanjani intambo yamandla yephinikhodi engu-2 efanele enomthamo wekhompuyutha?
Yebo, esihlokweni esandulele, ngabelane ngolwazi lwami lokubala amandla asetshenziswa yikhompyutha.Uma ungakayifundi, sicela ubuyekeze lesi sifundo: Ngaphezu kwalokho, uzothola imiyalelo yokubala ukusetshenziswa kwamandla kwekhompuyutha yedeskithophu (PC).
Uma ukhetha;noma iyiphi intambo yamandla yezikhonkwane ezi-2 engekho eqophelweni;izothinta ukusebenza kwesistimu yakho.Okokuqala kufanele kube nentambo yamandla yezikhonkwane ezi-2, esebenza kahle kakhulu kuwe.Udinga ukukunaka lokhu futhi ukwenzeleIntambo yamandla engu-2-pin enesitifiketi se-VDE.Izokunikeza imininingwane edingekayo.
I-Epilogue
Kulungile, lokho kunemininingwane futhi kucacile, akunjalo?Lolu ulwazi engiluthola luhle kakhulu futhi luwusizo kakhulu okufanele ukwazi mayelana nezinsiza zamandla zekhompyutha.Ukuthola imininingwane eyengeziwe, kungathatha isikhathi eside, kodwa sidinga nje ukwazi izici ezingenhla futhi kulungile
