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

KA7912 (-12 Volt Regulator)
KA7912 (-12 Volt Regulator)

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 (+ve Voltage Regulator)
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 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

Schematic Daim duab
Schematic Daim duab

Assamble tag nrho cov khoom raws li qhia hauv daim duab qhia chaw.

Kauj ruam 7: Txhua yam ua tiav
