Cov lus piav qhia ntxaws txog kev tsim kho ntawm DC lub zog ruaj khov
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm transformer yog raws li txoj cai ntawm electromagnetic induction rau kev hloov pauv ntawm qhov voltage, tam sim no thiab impedance. Thaum tsim lub DC tswj fais fab mov, lub hwj chim transformer feem ntau hloov ib qho -theem AC voltage ntawm 220V mus rau qis AC voltage kom tau raws li qhov yuav tsum tau ntawm cov nram qab no circuits. Txiav txim seb tus naj npawb ntawm cov qhov (socket) nyob rau sab thib ob ntawm lub hwj chim transformer thiab qhov voltage thiab wattage txhua lub qhov (socket) yuav tsum muab, raws li DC voltage thiab tam sim no qhov tseem ceeb ntawm Circuit Court. Tsis tas li ntawd, txhawm rau txo qhov ntim thiab qhov hnyav ntawm lub zog hloov pauv, yuav tsum xaiv lub siab - zaus fais fab transformer.
Siv unidirectional conductivity ntawm diode los hloov AC voltage mus rau DC unidirectional voltage yog hu ua rectification. Hauv kev tsim qauv tiag tiag, txoj kev kho kom raug tsim nyog yuav tsum raug xaiv raws li qhov tseeb ntawm cov zis thiab cov yam ntxwv zoo ntawm cov khoom siv hluav taws xob tsim.
Thaum tsim lub DC tswj fais fab mov, AC voltage tuaj yeem lim tau los ntawm cov yam ntxwv hauv qab no: qhov hluav taws xob thoob plaws lub zog cia khoom (xws li inductors thiab capacitors) tsis tuaj yeem hloov pauv mus rau DC cov zis nrog qhov hloov pauv tsawg. Lub lim DC lub zog tso zis ib txwm muaj ntau cov khoom siv AC, yog li nws tsis tuaj yeem siv ncaj qha hla lub thauj khoom thiab yuav tsum ruaj khov.
