1. Tawm
Ib qho tshwj xeeb ntawm linear stabilized fais fab mov yog tias nws cov khoom siv hluav taws xob tswj lub raj ua haujlwm nyob rau hauv cheeb tsam linear, thiab cov zis yog stabilized los ntawm qhov voltage poob ntawm cov regulator hlab. Vim qhov loj zoo li qub poob ntawm lub raj hloov kho, lub tshuab hluav taws xob loj yuav tsum tau muab ntsia kom dissipate nws. Thiab vim hais tias lub transformer ua haujlwm ntawm lub zog zaus (50Hz), qhov hnyav yog qhov loj.
Qhov zoo ntawm cov khoom siv hluav taws xob no yog kev ruaj ntseg siab, me me ripple, kev ntseeg siab, yooj yim rau ntau txoj hauv kev, thiab cov khoom tsim tawm tsis tu ncua adjustable tiav. Qhov tsis zoo yog tias nws loj, loj, thiab tsis muaj txiaj ntsig. Muaj ntau ntau hom khoom siv hluav taws xob ruaj khov, uas tuaj yeem muab faib ua cov khoom siv hluav taws xob tswj thiab tswj cov khoom siv hluav taws xob tam sim no los ntawm cov khoom siv hluav taws xob, thiab tswj thiab ruaj khov tam sim no (bistable) fais fab mov uas sib txuas cov kev tswj hluav taws xob thiab cov kev cai tam sim no. Kev txiav txim los ntawm tus nqi tso zis, nws tuaj yeem muab faib ua cov khoom siv hluav taws xob ruaj khov, hloov pauv hloov hom thiab potentiometer tsis tu ncua kho hom. Los ntawm cov lus qhia tso zis, nws tuaj yeem muab faib ua pointer indication type thiab digital display type thiab thiaj li nyob.
2. Hloov hom
Ib hom stabilized fais fab mov txawv ntawm linear stabilized fais fab mov yog hloov DC stabilized fais fab mov. Nws hom Circuit Court feem ntau suav nrog ib leeg-kawg flyback, ib leeg-kawg rau pem hauv ntej, ib nrab-bridge, thawb-rub thiab tag nrho-bridge. Qhov sib txawv ntawm nws thiab cov khoom siv hluav taws xob tawm yog qhov hloov pauv tsis ua haujlwm ntawm lub zog zaus tab sis ua haujlwm ntawm kaum ntawm kilohertz mus rau ob peb megahertz. Lub raj muaj nuj nqi tsis ua haujlwm hauv cheeb tsam saturation thiab txiav tawm, uas yog, hloov lub xeev; lub switching fais fab mov muaj npe tom qab nws.
Qhov zoo ntawm kev hloov fais fab mov yog qhov me me, lub teeb yuag, ruaj khov thiab txhim khu kev qha; qhov tsis zoo yog qhov ripple loj dua li ntawm cov khoom siv hluav taws xob tawm (feem ntau Tsawg dua lossis sib npaug li 1 feem pua VO (PP), qhov zoo tuaj yeem ua tiav ntau tshaj kaum mV (PP) lossis tsawg dua). Nws lub zog tuaj yeem yog los ntawm ob peb watts mus rau ob peb kilowatts.
