Raws li hom kev hloov hluav taws xob hloov hluav taws xob thiab cov khoom siv, kev tsheb ciav hlau hloov hluav taws xob feem ntau tuaj yeem pom hauv peb lub neej txhua hnub.Raws li txhua tus paub, cov neeg feem coob muaj kev nkag siab me ntsis ntawm nws cov kev paub thiab kev ua haujlwm.Ntawm no, cov neeg yuav coj koj mus rau tus tswv cov kev paub thiab kev ua haujlwm ntawm kev hloov hluav taws xob.
Cov khoom siv hluav taws xob hloov hluav taws xob yog cov khoom siv me me thiab nruab nrab ntawm cov khoom siv hluav taws xob, uas feem ntau yog tsim los ntawm lub casing, lub zog hloov hluav taws xob, lub toroidal transformer thiab inverter Circuit Court.Nws tuaj yeem muab faib ua AC tso zis hom thiab DC tso zis hom.Feem ntau, muaj ob hom software embedded phab ntsa thiab desktop hom.Nws feem ntau yog siv los txav cov xov tooj ntawm tes, koob yees duab, khoos phis tawj, arcade game consoles thiab lwm yam khoom siv hluav taws xob.
Tus qauv hloov hluav taws xob hauv peb lub teb chaws yog 220V alternating tam sim no, thiab feem ntau ntawm cov khoom siv hluav taws xob uas siv hluav taws xob tsawg tsis tuaj yeem dais qhov ua haujlwm voltage.Yog li ntawd, cov khoom siv hluav taws xob hloov pauv yuav tsum hloov 220V alternating tam sim no mus rau hauv lub zog ua haujlwm uas tuaj yeem ua raws li ntau yam khoom siv hluav taws xob.Hloov fais fab mov yog qhov muaj nyob ntawm xws li cov khoom siv hluav taws xob hluav taws xob hloov hluav taws xob.
Raws li cov cuab yeej siv hluav taws xob niaj hnub no, cov khoom siv hluav taws xob hloov hluav taws xob tau muab tua nyob rau hauv txoj kev hais saum toj no ntawm kev tswj cov khoom siv hluav taws xob, uas txhawb nqa cov nqi tam sim no uas ib txwm tso tawm los ntawm txhua yam.Cov ntsiab lus saum toj no yog cov khoom siv prefabricated yog pulse width modulation (PWM) tswj IC thiab MOSFET ntawm txoj kev tsheb ciav hlau hloov hluav taws xob.Ua raws li txoj kev loj hlob ntawm cov cuab yeej siv hluav taws xob niaj hnub no, cov txheej txheem ntawm kev hloov hluav taws xob hloov pauv kuj tseem txhim kho thiab kho dua tshiab.Hloov cov khoom siv hluav taws xob cuam tshuam txog kev tiv thaiv ib puag ncig, kev txuag hluav taws xob, kev ua haujlwm siab, tus nqi qis thiab kev yooj yim yog cov neeg uas nrhiav kev ua tiav.Hloov cov khoom siv hluav taws xob tau siv dav hauv ntau yam khoom siv hluav taws xob.Nws yog qhov pom tseeb tias lub zog hloov hluav taws xob hluav taws xob cov khoom siv hluav taws xob tau ntev dhau los ua ib feem tseem ceeb.
Cov khoom siv hluav taws xob hloov hluav taws xob tuaj yeem muab faib ua ob hom: DC hloov hluav taws xob khoom siv thiab AC hloov hluav taws xob khoom siv.
Ntawm ob hom kev siv hluav taws xob hloov hluav taws xob ntawm no, AC hloov hluav taws xob cov khoom siv tau siv nyob rau hauv lub neej txhua hnub yam tsawg kawg nkaus, thiab tsis muaj ntau, yog li hom DC hloov hluav taws xob tseem ceeb no txuas nrog hauv me me.DC switching fais fab mov muaj qhov zoo dua.Nws tuaj yeem hloov lub zog tsav tsheb thiab xa cov hluav taws xob ua haujlwm tsis zoo rau hauv DC ua haujlwm voltage (zoo) uas siv lub cev cov khoom rau hauv kev xav.Cov khoom tseem ceeb ntawm DC hloov hluav taws xob yog DC / DC converter.Nws kuj yog vim qhov tseem ceeb ntawm cov khoom siv hluav taws xob DC hloov hluav taws xob tuaj yeem hloov hluav taws xob ntxhib rau hauv hluav taws xob zoo.Yog li, DC / DC Cheebtsam kuj tuaj yeem hais tias yog qhov laj thawj tseem ceeb rau kev sib txawv ntawm DC lub zog hloov thiab AC lub zog hloov.
