Hloov ntawm computer fais fab mov mus rau ntau yam pab kiag li lawm

Lub computer ua hauj lwm pab peb ntau lub xyoo, los ua ib tug phooj ywg tiag tiag ntawm cov tsev neeg, thiab thaum twg nws yuav obsolete los yog hopelessly lawm, yog li ntawd thov txim rau nqa nws mus rau lub pob tseg. Tab sis muaj qhov chaw uas yuav kav mus ib lub sij hawm ntev nyob tom tsev. Qhov no Heev heev txias thiab processor tshav kub tog, thiab txawm lub cev. Tab sis qhov tseem ceeb tshaj plaws - qhov no PSU. Fais fab mov unit, ua tsaug rau ib tug dlej hwj chim nrog me me qhov ntev, yog qhov chaw zoo tagnrho txhua hom hloov khoom dua tshiab. Nws transformation - yog tsis xws li ib tug yooj yim ua hauj lwm.

Hloov ntawm computer fais fab mov unit rau lub cev qhov twg los voltage

Koj yuav tsum txiav txim siab zoo li cas thaiv koj lub computer fais fab mov, AT los yog ATX. Raws li txoj cai, qhov no yog qhia rau cov vaj tse nyob. Pulsed fais fab mov xwb ua hauj lwm nyob rau hauv load. Tab sis ATX hom fais fab mov unit tso cai rau lub kaw ntawm lub ntsuab thiab dub nyob ntawm tej kom qog ua raws nws artificially. Yog li ntawd, txuas lub load (rau AT) los yog los ntawm kev kaw cov kev tsim nyog cov lus xaus (rau ATC), koj yuav khiav tus kiv cua. Lub tso zis yog 5, thiab 12 volts. Maximum tso zis tam sim no nyob rau lub hwj huam mov unit. Thaum 200 watts, nyob pyativoltovom tso zis tam sim no muaj peev xwm mus txog qhov kev txiav txim ntawm 20A rau 12b - txog 8A. Yog li ntawd tsis muaj ntxiv nqi koj yuav txaus siab rau ib tug zoo qhov chaw ntawm cov khoom noj nrog zoo tso zis yam ntxwv.

Hloov ntawm computer fais fab mov mus rau lub cai voltage qhov chaw

Muaj ib tug PD hauv tsev los yog chaw ua hauj lwm yog heev yooj yim. Hloov ib tug txheej txheem tsev tsis yooj yim. Koj yuav tsum tau hloov ib tug ob peb resistors thiab vypayat throttle. Thaum zoo li no voltage nqi yuav tom ntawm 0 mus rau 20 volts. Lawm, lub currents yuav nyob twj ywm nyob rau hauv cov proportions. Yog hais tias koj yog txaus siab nrog lub siab tshaj plaws voltage ntawm 12V yog txaus mus teem nws cov zis thyristor voltage regulator. Lub regulator Circuit Court yog heev yooj yim. Nyob rau tib lub sij hawm nws yuav pab tau kom tsis txhob cuam tshuam nyob rau hauv lub internal ib feem ntawm lub computer chav tsev.

Hloov ntawm ib tug computer fais fab mov tsheb charger

Lub hauv paus ntsiab lus tsis yog, tsis zoo li ib tug cai fais fab mov. Tsuas yog nws yog ntshaw kom hloov cov Schottky diodes los ntau haib. Charger los ntawm lub hwj chim muab lub computer muaj ib tug xov tooj ntawm zoo thiab disadvantages. Qhov zoo feem ntau muaj xws li me me luaj li cas thiab lub teeb yuag. Transformer nco npaum li cas hnyav thiab ua tau txawv txawv los siv. Tsis zoo no kuj tseem ceeb: lub criticality ntawm ib tug luv luv-Circuit Court thiab rov qab polarity.

Ntawm cov hoob kawm, qhov no criticality yog pom nyob rau hauv transformer ntaus ntawv, tab sis tso zis AC fais fab tsis ua hauj lwm tus mem tes chav tsev nrog ib tug voltage ntawm 220V yog cog lus rau lub roj teeb. Nws yog txaus ntshai rau xav txog tej yam lub txim ntawm no rau tag nrho cov pab kiag li lawm thiab cov neeg nyob ze. Daim ntawv thov nyob rau hauv kev tiv thaiv khoom siv fais fab daws qhov teeb meem no.

Ua ntej siv xws li ib tug them ntaus ntawv, tiag Kho kom raug cov kev tiv thaiv Circuit Court. Qhov ntau li ntawd vim hais tias muaj ntau ntau ntau ntau yam.

Yog li ntawd, tsis txhob Rush mus pov tseg ntawm qhov chaw ntawm lub qub ntaus ntawv. Hloov ntawm computer fais fab mov yuav muab nws ib tug thib ob lub neej. Thaum ua hauj lwm nrog BP, nco ntsoov tias nws lub rooj tsavxwm yog tas li nyob rau 220V, thiab nws nruab nrab yog ib tug hauv ntiaj teb no kev hem thawj. Siv cov kev ruaj ntseg ceev faj thaum ua hauj lwm nrog hluav taws xob tam sim no.
