DC Power Supply System: Txoj Cai Ua Haujlwm, Hom, thiab Daim Ntawv Thov Hloov Hloov
DC Power Supply System yog dab tsi?
A DC fais fab mov systemyog ib feem tseem ceeb ntawm ntau yam khoom siv hluav taws xob niaj hnub. Nws muab lub zog ncaj qha ncaj qha (DC) rau cov khoom siv uas tsis tuaj yeem ua haujlwm ncaj qha los ntawm AC daim phiaj, suav nrog kev tswj hwm kev lag luam, cov khoom siv sib txuas lus, cov chaw nres tsheb, thiab lub zog cia.
Feem ntau cov khoom siv hluav taws xob muab hloov pauv tam sim no (AC), tab sis ntau cov khoom siv tseem ceeb yuav tsum muaj lub zog DC vim nws muaj qhov tso tawm hluav taws xob ruaj khov thiab tuaj yeem ua haujlwm ua ke nrog cov roj teeb thaub qab. Hauv kev siv tswv yim, ua tiavDC fais fab mov systemfeem ntau suav nrogtransformers, rectifiers, chargers, roj teeb, thiab DC cov khoom faib khoom.
Rau cov chaw tsim khoom lag luam thiab cov phiaj xwm hluav taws xob, lub zog hloov hluav taws xob txhim khu kev qha tsis yog hais txog kev muab hluav taws xob xwb. Nws kuj yog hais txog kev ua kom cov khoom siv tseem ceeb ua haujlwm zoo thiab tsis tu ncua, tshwj xeeb tshaj yog thaum muaj kev cuam tshuam tsis zoo ntawm lub zog.
DC Fais Fab Qhov System Ua Haujlwm Li Cas?
Lub zog DC fais fab mov hloov pauv AC lub zog nkag mus rau hauv cov khoom siv DC tswj los ntawm ntau theem. Cov txheej txheem yuav zoo li yooj yim, tab sis txhua yam khoom ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ruaj khov.
| Cheebtsam | Muaj nuj nqi |
