A DC fais fab movyog ib qho tseem ceeb nyob rau hauv ntau yam khoom siv hluav taws xob thiab tshuab. Nws muab cov khoom tsis tu ncua thiab ruaj khov ntawm cov khoom siv hluav taws xob ncaj qha (DC) rau lub zog hluav taws xob hluav taws xob thiab cov khoom siv. Tsis zoo li cov khoom siv hluav taws xob hloov pauv tam sim no (AC), uas hloov pauv hauv qhov hluav taws xob thiab kev taw qhia,DC cov khoom siv hluav taws xobxa ib qho kev khiav dej num ntawm hluav taws xob hauv ib qho kev taw qhia. Kab lus no tsom mus tshawb txog qhov tseem ceeb ntawmDC cov khoom siv hluav taws xob, lawv cov ntawv thov, thiab ntau hom muaj nyob hauv khw.
DC cov khoom siv hluav taws xobyog siv nyob rau hauv ntau yam kev siv, nrog rau kev ntsuam xyuas hluav taws xob, kev sib txuas lus, kev lag luam automation, thiab kev tshawb fawb tshawb fawb. Lawv feem ntau ua haujlwm hauv cov chaw kuaj hluav taws xob thiab cov chaw tsim khoom siv hluav taws xob thiab ntsuas cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Ntxiv thiab,DC cov khoom siv hluav taws xobyog siv nyob rau hauv ntau yam khoom siv hluav taws xob, xws li laptops, smartphones, thiab portable electronic devices. Cov khoom siv hluav taws xob no tseem yog ib qho tseem ceeb hauv kev siv hluav taws xob tsheb, hluav taws xob txuas ntxiv dua tshiab, thiab kev sib txuas lus hauv tsev.
Muaj ob peb homDC cov khoom siv hluav taws xobmuaj, txhua tus tsim los rau cov ntawv thov tshwj xeeb thiab cov kev xav tau. TawmDC cov khoom siv hluav taws xobpaub txog lawv txoj kev yooj yim thiab kev ntseeg tau, muab qhov tso zis hluav taws xob ruaj khov nrog cov suab nrov tsawg tsawg. HloovDC cov khoom siv hluav taws xob, ntawm qhov tod tes, muaj txiaj ntsig zoo dua thiab kev cog lus, ua rau lawv tsim nyog rau kev siv qhov chaw thiab kev siv hluav taws xob yog qhov tseem ceeb. ProgrammableDC cov khoom siv hluav taws xobmuaj cov yam ntxwv siab heev xws li kev tswj chaw taws teeb, qhov hluav taws xob thiab kev ua haujlwm tam sim no, thiab cov kev hloov kho cov zis, ua rau lawv zoo tagnrho rau kev tshawb fawb thiab kev loj hlob ib puag ncig.
Lub hauv paus ntsiab lus ntawm aDC fais fab movNws suav nrog kev hloov AC voltage los ntawm cov khoom siv hluav taws xob rau hauv qhov tso zis DC ruaj khov. Cov txheej txheem hloov dua siab tshiab no feem ntau suav nrog kev kho, lim dej, thiab kev tswj hluav taws xob. Nyob rau hauv lub rectification theem, AC voltage yog hloov dua siab tshiab rau hauv pulsating DC voltage siv diodes. Tom qab ntawd, lim siv cov capacitors los txo cov ripple thiab hloov pauv hauv cov zis voltage. Thaum kawg, theem kev tswj hwm qhov hluav taws xob ua kom ntseeg tau tias qhov tso zis hluav taws xob tseem nyob tas li, tsis hais qhov kev hloov pauv ntawm cov khoom siv hluav taws xob lossis cov khoom thauj khoom.
Hauv kev xaus,DC cov khoom siv hluav taws xobua lub luag haujlwm tseem ceeb hauv kev siv hluav taws xob hluav taws xob thiab tshuab thoob plaws ntau yam kev lag luam. Lawv lub peev xwm los muab qhov chaw ruaj khov thiab zoo ib yam ntawm cov hluav taws xob ncaj qha tam sim no ua rau lawv tseem ceeb hauv kev ntsuas hluav taws xob, kev tsim khoom, thiab cov khoom siv hluav taws xob. Nrog ntau homDC cov khoom siv hluav taws xobmuaj, suav nrog linear, hloov, thiab cov qauv programmable, cov neeg siv tuaj yeem xaiv cov kev xaiv tsim nyog tshaj plaws raws li lawv cov kev xav tau tshwj xeeb. Nkag siab txog cov ntsiab cai tseem ceeb ntawmDC cov khoom siv hluav taws xobthiab lawv cov ntawv thov yog qhov tseem ceeb rau cov engineers, cov kws tshaj lij, thiab cov neeg nyiam ua haujlwm nrog cov tshuab hluav taws xob thiab cov khoom siv.
