Nyob Zoo Cov Phooj Ywg raws li cov khoom siv hluav taws xob peb txhua tus xav tau lub zog siv hluav taws xob ntawm lub rooj zaum ua haujlwm, peb tseem xav tau -v cov tsheb nqaj hlau siv hluav taws xob rau ntau yam khoom siv hluav taws xob Eg- OpAmp thiab lwm yam niaj hnub no hauv ntu no kuv yuav mus pom ntau hom khoom siv hluav taws xob ua ntawm cov khoom siv hluav taws xob sib xws,. Yog xav paub ntau ntxiv thov mus saib kuv li channel lossis saib cov vis dis aus saum toj no.
Kauj ruam 1: Kauj Ruam Down Transfarmer
Hauv qhov Project 12-0-12 volt chaw tapped hloov pauv tau siv los nqis qis qhov hluav taws xob, vim nws muaj zog dua thiab yooj yim los daws qhov SMPS, vim nws yooj yim kuv siv nws hauv kuv txoj haujlwm.
Kauj Ruam 2: KA7912 (-12 Volt Regulator)
KA7912 yog siv los tswj -v Rail ntawm lub zog siv Raws li qhov no yooj yim heev rau siv hauv txoj haujlwm no.
Pin 1 = GND (ntau)
Pin2 = -ve tswv yim
Pin3 = Cov zis
Kauj Ruam 3: LM7812 (+ve Voltage Regulator)
LM7812 siv nyob rau hauv txoj haujlwm no los tswj hwm +muab cov tsheb nqaj hlau rau +12v.
Pin 1 = Cov tswv yim
Pin 2 = GND (Common)
Pin3 = Cov zis
Kauj Ruam 4: Choj Rectifier
Choj kho hluav taws xob tau siv hauv txoj haujlwm no los hloov AC teeb liab mus rau DC, Kev txhim kho choj tuaj yeem ua tau siv 4 Diodes. IN4007 (1000volt 1Amp) Cov.
Kauj ruam 5: Capacitor
Capacitor siv hauv txoj haujlwm no siv los hloov pauv pulsating DC rau Smooth DC. Txhawm rau kom muaj kev ruaj ntseg zoo.
Kauj Ruam 6: Daim duab qhia chaw
Assamble tag nrho cov khoom raws li qhia hauv daim duab qhia chaw.
Kauj ruam 7: Txhua yam ua tiav
Txhua Cheebtsam tau sib sau ua ke hauv PCB. Yog tias koj xav pom nws ua haujlwm koj tuaj yeem tshawb xyuas kuv cov vis dis aus
