Kev Ua Haujlwm Lub Hauv Paus Ntawm Kev Hloov Khoom Siv Hluav Taws Xob
Cov khoom siv ua haujlwm ntawm hloov fais fab kev ua haujlwm tau yooj yim, nyob rau hauv ob lub dav hlau, thiab tam sim no yog loj, tus hluav taws xob yog qhov siab, Thiab tam sim no yog me me) / Fais zog ntaus tus volt-ampere cov khoom ntawm lub zog transistor yog qhov poob tshwm sim ntawm lub zog sliconductor ntaus ntawv. Piv rau cov khoom siv hluav taws xob tawm, PWM hloov cov khoom siv hluav taws xob ntau dua los ntawm pulses nrog cov kev sib npaug nrog cov kev sib npaug ntawm cov tswv yim voltage. Lub luag hauj lwm ntawm cov mem tes yog kho los ntawm tus tswj ntawm lub hloov pauv fais fab mov. Thaum lub tswv yim voltage yog tws rau hauv ac square yoj, nws qhov loj tuaj tau tsa lossis txo qis los ntawm tus hloov pauv. Tus naj npawb ntawm cov zis hluav taws xob pab pawg tuaj yeem nce ntxiv los ntawm kev nce tus naj npawb ntawm cov windings thib ob hauv lub transformer. Thaum kawg no cov ntaub ntawv Willforms yog rectified thiab lim kom tau txais cov zis tawm voltage. Lub hom phiaj tseem ceeb ntawm tus maub los yog kom cov zis voltage ruaj khov, thiab nws cov txheej txheem ua haujlwm zoo heev li ntawm cov maub los ntawm maub los. Qhov no txhais tau hais tias lub pob zeb ua haujlwm ntawm tus maub los, cov voltage siv thiab qhov yuam kev amplifier, tuaj yeem tsim nyob rau hauv tib txoj kev raws li nyob rau hauv ib tug linear regulator. Qhov sib txawv yog tias cov zis ntawm qhov yuam kev uas nthuav dav (qhov yuam kev voltage) dhau los ntawm kev hloov pauv hloov tshiab dua ua ntej tsav lub hwj chim. Hloov cov khoom siv fais fab muaj ob hom qauv ntawm kev ua haujlwm: kev hloov dua siab tshiab thiab hloov dua siab tshiab. Txawm hais tias qhov sib txawv hauv kev npaj ntawm lawv cov khoom siv yog me, cov txheej txheem kev ua haujlwm sib txawv, thiab txhua tus muaj nws tus kheej zoo rau ib daim ntawv thov tshwj xeeb.
Peb Qhov Mob rau Hloov Cov Khoom Siv Hluav Taws Xob
Hloov
Lub zog hluav taws xob ua haujlwm hauv lub xeev hloov pauv ntau dua li txoj kab linear.
Siab ntau
Lub hwj huam hluav taws xob ua haujlwm ntawm lub zog loj dua li ntawm qhov tsawg zaus ze ntawm kev lag luam ntau.
Dc
Hloov Powering fais fab tso zis DC hloov ACC lossis lawv tuaj yeem tso tawm cov pob hluav taws xob ntau li hluav taws xob hloov hluav taws xob.
Kev faib tawm ntawm cov khoom siv fais fab fais fab
Cov neeg nyob hauv lub teb ntawm hloov fais fab kev siv tshuab yog sab ntawm kev hloov pauv hluav taws xob hauv lub zog, me me, muaj suab nrov ib xyoos ib zaug, kev ntseeg siab, tiv thaiv kev tawm tsam kev txhim kho. Hloov chaw fais fab tuaj yeem muab faib ua AC / DC ob pawg, yog qhov ua tiav ntawm ACverter DC / DC, thiab tau raug lees paub los ntawm cov txheej txheem ntawm cov txheej txheem hauv tsev, ntsib cov txheej txheem ntawm kev teeb meem, tau pom cov txheej txheem ntawm cov txheej txheem hauv tsev kawm ntawv thiab cov yam ntxwv ua tiav, ntsib cov cuab yeej siv ntau dua, tau ntsib ib qho kev coj ua, tau ntsib cov cuab yeej siv ntau dua Cov teeb meem txheej txheem kev tsim qauv. Cov qauv thiab cov yam ntxwv ntawm ob hom hloov mus hloov fais fab khoom siv tau piav qhia hauv qab no.
