Zoo, nws tau ua tiav me ntsis, tab sis kuv xav tias nws muaj txiaj ntsig zoo uas kuv yuav ua ib yam nkaus. Cov lus qhia no yuav dhau los ntawm cov theem pib ntawm kev tsim koj tus kheej lub zog hluav taws xob me me, zoo ib yam li cov 'phab ntsa pob zeb' thaum koj xav tau ib qho ntawm qhov tshwj xeeb hluav taws xob, lossis xav tau hloov ib qho uas koj kib.

Kauj Ruam 1: Nqis Nqis Phab Ntsa Voltage

Thawj kauj ruam ntawm kev tsim ib qho ntawm cov khoom siv hluav taws xob no yog txhawm rau nqis cov phab ntsa hluav taws xob mus rau qee yam hauv zej zog ntawm yam koj xav tau. Kuv tau tshwm sim los yuav ob peb ntawm cov khoom hloov pauv uas tau nce mus txog 120Vac mus rau 12Vac, tab sis koj tuaj yeem siv tau ib qho kev hloov pauv uas ua tau txo qhov hluav taws xob txaus los ntawm 120Vac. kwv yees tias txhua qhov uas tau muab tshem tawm yuav zoo ib yam li qhov paub tsis meej. Thawj sab tau qhia tau yooj yim los ntawm qhov hnyav dua ntawm cov xaim. Ib qho scavenged plug tau soldered mus rau thawj, thiab qhov txuas tau lopped tawm ntawm qib thib ob, raws li kuv yuav tsis siv nws ib qho ntxiv. yog ntau npaum li cas tam sim no uas koj yuav kos los ntawm nws. Qhov loj me zoo li yog qhov qhia tias koj tuaj yeem kos tau ntau npaum li cas, tab sis ntawm no, yog tias nws tsis tau teev nyob rau qee qhov, Kuv feem ntau mus tom ntej nrog nws thiab txheeb xyuas kom paub tseeb tias nws tsis kub hnyiab heev thaum kawg ntawm txhua qhov. Txhua Lub Sijhawm Koj Ruaj Ntseg Txhua Yam Rau Hauv Phab Ntsa, Ua tib zoo saib xyuas ntxiv txog qhov koj tso koj txhais tes, thiab Dab Tsi Ua Hluav Taws Xob !!!

Kauj Ruam 2: Rectifying Stepper Down Voltage

Yog li tam sim no tias qhov hluav taws xob tau nqis qis ntawm phab ntsa, peb xav ua kom nws DC. Thawj kauj ruam rau qhov no yog kho qhov teeb meem hluav taws xob.

Kuv txoj kev nyiam ua qhov no yog kev siv tus choj rectifier. Muaj ob peb txoj hauv kev los ua qhov no txawm li cas los xij, yog tias koj muaj rectifier diodes dai ncig ntawm lwm yam uas koj tau sib nrug, koj tuaj yeem tsim koj tus kheej yooj yim. Lossis, koj tuaj yeem tau txais ib qho uas tau npaj ua ntej uas muaj los ntawm Fairchild lossis lwm lub tuam txhab koom tes. Zoo nkauj npaum li qhov tsuas yog txhawj xeeb txog yog kom ntseeg tau tias txhua yam uas koj siv yuav ua haujlwm nyob hauv nws thaj tsam. Txheeb xyuas txhua cov ntaub ntawv muaj los xyuas kom tseeb tias koj yuav tsis sim thiab rub ntau dhau tam sim no los ntawm lub rectifier. Yog tias tsis muaj cov ntawv txheeb tseg, piv txwv li koj tau siv scavenged diodes los tsim koj tus kheej rectifier, Kuv feem ntau tsuas yog mus tom ntej thiab tsim nws ib qho twg, thiab pom ntau npaum li cas txhua yam ua kom sov.

Kauj ruam 3: Lim

Yog li tam sim no uas peb tau kho qhov hluav taws xob, peb tau hloov qhov teeb liab hluav taws xob los ntawm sine yoj mus rau qhov ntau lossis tsawg dua qhov muaj txiaj ntsig ntawm nws tus kheej. Tam sim no dab tsi tseem tshuav yog ua kom nws du. Yog li peb tsuas yog yuav ntxig lub capacitor ua ke ntawm qhov av thiab qhov hluav taws xob. Qhov no yog cov kauj ruam yooj yim heev, tshwj xeeb tshaj yog txij li cov hluav taws xob hluav taws xob muaj ntau, thiab tej zaum koj yuav muaj qee yam tawg dag nyob ib puag ncig uas koj tuaj yeem rub ib qho tawm ntawm. Ntawm no, tus nqi loj dua yog qhov zoo dua, tab sis koj tsis tas yuav tsum tau hla mus. Kuv tsuas yog muab tus nqi loj thiab tom qab ntawd hloov nws nrog qhov me me thiab qhov tseem ceeb kom txog thaum lub ripple tau txais qhov tsis txaus rau kuv txhawj xeeb txog nws.. Ntawm no, koj yuav tsum ua kom ntseeg tau tias cov ntsuas hluav taws xob ntsuas hluav taws xob tsis dhau. Nws yuav yog lub tswv yim zoo los ntsuas qhov no kom ntseeg tau. Sab nrog kab txaij ntawm nws yog sab uas koj yuav tsum muab tso rau qhov tsis zoo tshaj qhov hluav taws xob. Kuv tsuas yog tau pom nws ib zaug, tab sis thaum lub tshuab hluav taws xob hluav taws xob muab tso rau sab nraum qab, nws tuaj yeem tawg.

Kauj Ruam 4: Kev Tswj

Cov kauj ruam no yog qhov tsim nyog txhawm rau txhawm rau tshem tawm qhov hluav taws xob, ua kom nws tawm me ntsis ntxiv thiab muab koj qhov kawg, qhov xav tau qhov hluav taws xob tso tawm.

Ib zaug ntxiv, koj tuaj yeem ua cov kauj ruam no hauv ob peb txoj kev sib txawv. Ua ntej koj tuaj yeem nplawm tus tswj zener, yog tias koj tshwm sim muaj zener diode ib puag ncig uas haum rau qhov tso zis hluav taws xob koj xav tau. Tus kheej, Kuv nyiam lwm txoj kev. Ntau qhov 'ntsaws thiab chug' mus kom ze, txoj hauv kev no tsuas yog siv lub tshuab ntsuas hluav taws xob npaj ua ntej npaj tau muaj los ntawm txhua tus naj npawb ntawm cov tuam txhab sib txawv. Zoo nkauj npaum li txhua yam koj yuav tsum tau ua yog kom ntseeg tau tias nws yuav tuav tam sim no koj yuav rub los ntawm nws, thiab tias koj tab tom muab nws nrog qhov hluav taws xob sab hauv ntawm nws cov tswv yim ntau. Ib qho ntawm cov uas kuv tau tsim los kom muaj qhov hluav taws xob poob qis me ntsis ntxiv yog li kuv xam tawm qhov loj me ntawm tus tiv thaiv xav tau los tso cov hluav taws xob nkag rau hauv qhov tsim nyog. Yog tias koj yuav tsum ua qhov no, tsuas yog nco ntsoov lub zog tso tawm. Tsis tas li, qee tus tswj hwm xav tau lub tshuab hluav taws xob me me ua ke nrog cov khoom tso tawm kom ruaj khov nws. Cov ntawv yuav hais txog yog tias nws xav tau ib lossis tsis yog.

Kauj Ruam 5: Lwm Yam Kev Nyab Xeeb Kev Nyab Xeeb thiab Ua Kom tiav

Yog li, tam sim no koj tau txais lub zog DC me me. Nws tuaj yeem raug teeb tsa tas mus li ntawm lub rooj tsavxwm, lossis siv ib ntus yog tias koj tso nws ntawm koj lub khob cij. Tsuas yog saib, yam koj txuas rau nws, kom koj tsis txhob kib ib yam ntawm cov khoom, thiab ua tib zoo saib xyuas nrog tus hloov pauv ntawd, zoo li nws tau ntsaws rau hauv phab ntsa.
