Qhov cuam tshuam ntawm DC tswj fais fab mov ntawm cov khoom siv hluav taws xob
Vim yog cov yam ntxwv ntawm cov cuab yeej siv hluav taws xob, qhov yuav tsum tau muaj cov khoom siv hluav taws xob rau lub zog hluav taws xob yuav tsum muaj peev xwm muab lub zog txuas ntxiv thiab ruaj khov uas ua tau raws li qhov yuav tsum tau ua, thiab feem ntau yuav tsum muaj zog DC ruaj khov. Lub zog hluav taws xob uas muab lub zog DC ruaj khov no yog DC tswj fais fab mov. Raws li kev ua haujlwm ntawm cov kav dej tswj, DC tswj cov khoom siv hluav taws xob tuaj yeem muab faib ua ob pawg, cov khoom siv hluav taws xob linear tswj thiab hloov cov khoom siv hluav taws xob.
Output voltage ntau
Cov zis hluav taws xob ntau uas tuaj yeem ua haujlwm ib txwm nyob rau hauv cov xwm txheej ntawm DC tswj fais fab mov. Qhov txwv sab sauv ntawm qhov ntsuas no tau teev los ntawm qhov siab tshaj plaws input voltage thiab qhov tsawg kawg nkaus input-tso tawm voltage qhov sib txawv, thaum nws qis qis yog txiav txim siab los ntawm tus nqi siv hluav taws xob hauv DC tswj fais fab mov.
Qhov siab tshaj plaws input-output voltage sib txawv
Qhov ntsuas no sawv cev rau qhov siab tshaj plaws qhov sib txawv ntawm qhov kev tawm tswv yim thiab cov zis raws li kev ua haujlwm ib txwm muaj ntawm DC tswj fais fab mov. Nws tus nqi feem ntau yog nyob ntawm qhov ntsuas qhov ntsuas hluav taws xob ntawm qhov hloov pauv sab hauv ntawm DC tswj fais fab mov.
Yam tsawg kawg nkaus input-output voltage sib txawv
Qhov ntsuas no sawv cev rau qhov tsawg kawg nkaus input-output voltage qhov sib txawv uas yuav tsum tau ua kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm DC tswj fais fab mov.
1. Kev cuam tshuam ntawm qhov input voltage ntau. Thaum cov input voltage siab dhau lawm, qee cov khoom yuav raug puas vim yog siv hluav taws xob ntau dhau los yog siv zog ntau dhau. Thaum cov input voltage tsawg dhau lawm, kev ua haujlwm ntawm qee cov khoom yuav raug degraded. , txawm tsis ua haujlwm.
2. Qhov cuam tshuam ntawm qhov tsis ruaj tsis khov. Piv txwv li, lub hwj chim mov ntawm lub oscilloscope yuav tsum ruaj khov los xyuas kom meej qhov tseeb ntawm deflection rhiab heev ntawm lub teeb pom kev, scanning lub sij hawm, thiab lwm yam .; Lwm qhov piv txwv yog tias digital voltmeter yuav tsum muaj lub zog ruaj khov hauv lub zog kom ntseeg tau qhov tseeb ntawm qhov voltage / lej. Kev hloov siab lees txim.
3. Qhov cuam tshuam ntawm overvoltage ntawm cov zis kawg. Piv txwv li, thaum cov zis voltage ntawm DC tswj fais fab mov tshaj qhov ntsuas hluav taws xob ntawm cov hluav taws xob sib xyaw ua ke ntau dua 30%, nws yuav ua rau muaj kev puas tsuaj loj rau lub voj voog sib txuas.
4. Qhov cuam tshuam ntawm lub zog hluav taws xob luv luv. Piv txwv li, kev sib txuas lus hauv xov tooj hauv zos tsis tuaj yeem muaj hluav taws xob tam sim ntawd, txwv tsis pub kev sib txuas lus thoob ntiaj teb yuav cuam tshuam thiab ua rau muaj xwm txheej loj; Lwm qhov piv txwv yog tias thaum lub khoos phis tawj siv hluav taws xob los ntawm AC, AC lub zog tsis cuam tshuam yuav tsum tau siv.
Qhov no qhia tau hais tias lub luag haujlwm tseem ceeb ntawm DC tswj fais fab mov yog nyob rau hauv cov khoom siv hluav taws xob. Nws tuaj yeem tshem tawm cov teebmeem no thiab ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob.
