Feem ntau lub computer tsim tawm nrog qee cov ntaub ntawv qhia kev. Tab sis nyob rau hauv tus txheej txheem ntawm kev ua haujlwm, nws tiav niam txiv tsim nyog los nce lub zog ntawm qee yam tsis suav. Qhov ua tau zoo ntawm lub tshuab computer feem ntau nyob ntawm lub hwj huam hluav taws xob. Nyob rau lub sijhawm no, ntau tus pib nug txog kev nce hauv lub zog ntawm lub zog siv hluav taws xob. Txhawm rau ua txoj haujlwm no, koj yuav tsum tau ua raws qee txoj cai.

Cov Lus Qhia
Kauj ruam 1
Txhawm rau txhawm rau ntxiv lub zog ntawm kev txuas hluav taws xob, koj yuav tsum qhib nws.
Kauj ruam 2
Tom ntej no, koj yuav tsum tau kwv yees qhov loj me ntawm transformer. Yog tias lawv "3x3x3" cm thiab siab dua, koj tuaj yeem ruaj ntseg mus rau qhov kev kho nqi lus.
Kauj ruam 3
Lub ntsuas hluav taws xob loj loj tau hloov ua ntej. Nws raug nquahu kom tsis pub tsawg tshaj 470mkfx200V. Kev txhawm chim tau txhim tsa tsuas yog nyob hauv qhov qis-ntu hluav taws xob ntawm lub zog fais fab. Lawv tau ua ntau txoj hauv kev.
Kauj ruam 4
Koj tuaj yeem sim winding lub lacquered xaim nyob ib ncig ntawm lub nplhaib ferrite koj tus kheej. Qee tus neeg tshem cov txhawm chim ntawm PSUs qub.
Kauj ruam 5
Kev siv lub tshuab hluav taws xob muaj qhov sib npaug hauv cov chaw khoob hauv qhov hluav taws xob tsawg. Peb 2200mkfx16V capacitors tau txaus.
Kauj Ruam 6
Nws yog ib qho tsim nyog los hloov lub diode sib dhos. Nws raug nquahu kom muab 2 lossis 3 lub rooj sib txoos MOSPEC S30D40, lossis qee yam zoo sib xws. Txhua yam no yog yuav hauv khw muag khoom.
Kauj Ruam 7
Lub zog muab hluav taws xob muaj raws li + 5V thiab + 12V. Cov kab hluav taws xob uas tsis muaj qhov tseem ceeb ntawm qhov thib ob channel (+12) yog qhov phom sij rau koj lub computer. Txo txo qhov ntsuas no, nws yog qhov tsim nyog los ua kom nrov dua lub hauv paus tawg mus rau hauv qhov tawg ntawm cov tsav daj. Qhov ntsuas hluav taws xob yog txo 0.6V, uas yuav tiv thaiv koj lub computer.
Kauj ruam 8
Raws li qhov txiaj ntsig ntawm kev ua haujlwm nqa tawm, ib qho hluav taws xob tsis muaj tseeb kiag li. Nws yuav ua haujlwm zoo rau ntau xyoo. Nrog rau cov hluav taws xob muaj zog tshiab, koj tau txais cov txiaj ntsig ua tau zoo.
