Taw qhia rau cov lus txhais, qhov zoo, thiab cov ntawv thov ntawm DC Fais Fab Khoom Siv
DC fais fab mov yog lub zog ntaus ntawv uas hloov lwm txoj kev hloov tshiab rau hauv qhov tam sim no. Nws converts hloov tam sim no rau hauv ruaj khov thiab txuas ntxiv mus ncaj qha tam sim no los ntawm kev siv circuits xws li rectifiers, lim dej, thiab voltage regulators. Cov zis hluav taws xob ntawm cov khoom siv hluav taws xob DC tuaj yeem hloov kho raws li xav tau thiab feem ntau muaj cov ripple tsawg thiab siab ruaj khov.
Qhov zoo ntawm DC fais fab mov:
Piv rau AC fais fab mov, DC cov khoom siv fais fab muaj cov txiaj ntsig zoo hauv qab no:
2.1 ruaj khov:
DC cov khoom siv fais fab tuaj yeem muab cov voltage tawm ruaj khov vim tias nws undergoes rectification thiab lim ua nrog kev sib cais tsawg. Qhov no yog qhov tshwj xeeb tshaj yog rau qee cov khoom siv uas xav tau ntau voltage, xws li cov cuab yeej siv kho mob, thiab khoom siv kev siv khoom siv.
2.2 Kho tau:
Cov zis hluav taws xob ntawm cov ntaub ntawv DC fais fab tuaj yeem hloov kho raws li xav tau. Qhov no ua rau DC lub zog siv kom haum rau cov kev xav tau ntawm cov khoom siv sib txawv thiab muab cov voltage uas yuav tsum tau thiab tam sim no.
2.3 efficiency:
DC cov khoom siv hluav taws xob muaj zog dua thiab tuaj yeem ua tau zoo dua ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig piv rau AC fais fab. Vim tias qhov tseeb tias DC lub hwj chim tsis tas yuav muaj kev hloov pauv ntau zaus, nws tuaj yeem txo kev siv lub zog thiab lub zog siv thaum muaj kev kis mob.
2.4 Tsawg Ripple:
Tom qab recification thiab lim, output dc lub zog ntawm DC cov khoom siv tsis muaj feem ntau muaj cov ripple tsawg. Qhov no tseem ceeb heev rau qee cov khoom siv uas xav tau cov hluav taws xob siab, xws li khoos phis tawj, cov cuab yeej sib txuas lus.
2.5 Kev hloov kho:
Raws li DC cov khoom siv DC tuaj yeem hloov kho raws li xav tau, nws tuaj yeem hloov kho lub zog siv hluav taws xob. Seb nws yog tsawg {{- fais fab txawb khoom siv, DC cov khoom siv fais fab muaj peev xwm muab lub zog hluav taws xob uas xav tau.
