Txheej txheem cej luam:
Qhov me me AC rau DC Voltage Converter txoj haujlwm siv plaub diodes los ua ib lub choj kho kom hloov AC zog mus rau DC zog. Tsis tas li, peb siv cov khoom siv hluav taws xob tshem tawm cov ripples hauv Circuit Court. Tom qab peb hloov los ntawm AC zog mus rau DC lub zog, peb yuav tsum siv ib qho 5v qhov ntsuas hluav taws xob kom muab 5v DC tso tawm los ntawm 12 v DC tso tawm.
Yam Koj Yuav Tsum Tau:
Transformer 12VAC 20VA (Lee tus ID: 10641)
IN4001 Diode (Lee tus ID: 796)
16V 1000UF Electrolytic Cap (Lee tus ID: 867)
50V 0.1UF Ceramic Cap (Lee tus ID: 8175)
50V 0.22UF Ceramic Cap (Lee tus ID: 8174)
Breadboard (Lee tus ID: 10686)
Jumper Wires (Lee tus ID: 21802)
Mini Voltage Zaub (Lee tus ID: 1265)
IC Regulator 7805 +5V 1A (Lee tus ID: 7115)
Kauj ruam 1: Xaiv Transformer
Hauv txoj haujlwm no peb xaiv 12VAC 20VA hloov pauv nrog cov ntsia hlau hauv qab. Txhawm rau ua kom lub zog hluav taws xob hloov pauv nrog lub tshuab hloov pauv no, peb yuav tsum tau ntsia hlau jumer xaim tus pin sab hauv thiab ntsaws rau ntawm lub khob cij. Vim tias qhov no yog AC fais fab mov, qhov zoo thiab tsis zoo tsis muaj teeb meem.
Kauj Ruam 2: Tsim Tus Choj Rectifier Nrog Ib Lub Capacitor nyob rau hauv Parallel Nrog Nws
Hauv cov kauj ruam no, peb tsim tus choj txhim kho uas tsim los ntawm plaub 1N4001 diodes. Tom qab ntawd, peb sib dhos qhov ntsuas hluav taws xob no nrog rau 1000uf ua ke kom tshem qee qhov ripple. Qhov yuav tsum tau pom yog qhov tsis sib xws, nco ntsoov cov kab nyiaj ntawm lub diode qhia tias nws yog cathode davhlau ya nyob twg. Tom qab ua tiav lub tsev, thov siv lub ntsuas hluav taws xob me me los ntsuas qhov ntsuas hluav taws xob hla lub capacitor. Nws yuav muab koj ib puag ncig 18v DC zog.
Kauj Ruam 3: Ntxiv Tus Tswj Hluav Taws Xob kom muab 5v DC Tso Tawm
Hauv theem no, peb yuav tsum siv 5v IC Regulator, ib qho 0.1uf ceramic capacitor, ib qho 0.22uf ceramic capacitor thiab ib qho 1000uf electrolytic capacitor. Rau IC tus tswj hwm, nrog cov hlau lead hauv qab, sab laug yog cov tswv yim, nruab nrab yog hauv av thiab sab xis yog tso tawm. Tom qab ua tiav lub tsev tsim hluav taws xob, koj tuaj yeem siv qhov ntsuas hluav taws xob los ntsuas qhov ntsuas hluav taws xob los ntawm kev sib piv nws nrog qhov kawg ntawm 1000uf capacitor. Koj yuav pom cov zis yog 5v DC.
Kauj Ruam 4: Kev Txhim Kho Yav Tom Ntej
Hauv txoj haujlwm no, peb tsuas tuaj yeem muaj 5v DC tso tawm. Txawm li cas los xij, peb tuaj yeem sim txiav txim siab tawm qhov hluav taws xob los ntawm 0v txog 12v DC. Qhov no tuaj yeem daws tau los ntawm kev hloov Voltage regulator 7805 nrog qhov hloov pauv qhov ntsuas hluav taws xob LM317.
