Hloov pauv yooj yim 30v 2A Lub Hwj Huam Muab Los Ntawm Khaub Ncaws

Cov khoom siv hluav taws xob yooj yim no tuaj yeem muab 30v ntawm 2A.

Nws siv LM317 los hloov qhov tso tawm nrog kev ua haujlwm tau zoo.

Nws tuaj yeem siv los txhawb txhua yam los ntawm kev siv hluav taws xob mus rau lub cav. Nws yuav coj koj tsawg dua ob teev los sib sau ua ke, piv txwv tias koj tau ua cov phiaj xwm cuam tshuam nrog khoom siv hluav taws xob ua ntej, thiab muaj qee qhov txuj ci ua haujlwm.

Transformer

Transformer yog lub plawv ntawm kev tsim. Kuv tau txais 12-0-12 tus hloov pauv, uas txhais tau tias nws muaj peb qhov tso tawm, +12v, 0v (hauv av), thiab +12v.

Rectifier IC

Qhov no yuav tsum tau hloov AC rau DC.

lwm txoj hauv kev, koj tuaj yeem siv lub rectifier pom zoo ua los ntawm plaub lub diodes.

LM317 thiab Cov cua sov

qhov no yog qhov hloov pauv qhov ntsuas hluav taws xob IC. nws tuaj yeem ua kom sov, thiab kom tshem tawm cov cua sov ntawd, peb xav tau lub dab dej kub.

Vriable resistor (10k)

Qhov no thiab LM317 yuav sib txawv qhov hluav taws xob.

yog tias koj siv qhov kev tiv thaiv ruaj khov, koj yuav tau txais cov zis ruaj khov.

Kauj Ruam 2: Sib dhos Circuit

Sib dhos Circuit Court
Sib dhos Circuit Court

-Tau lub rectifier thiab ICs raws li Circuit Court.

-Txoj kev hloov pauv hloov cov theem hluav taws xob mus rau 12v-0v-12v raws li peb lub tappings.

Txij li nws yog AC, tsis muaj + thiab -. Yog li peb tuaj yeem nqa ob lub xov tooj 12v thiab tau txais 24v.

-Cov rectifier IC hloov pauv AC mus rau DC.

-The +ve los ntawm lub rectifier mus rau lub tswv yim ntawm tus tswj hwm.

-qhov nruab nrab tus pin ntawm tus tswj hwm tau txuas nrog ua ke ntawm kev tiv thaiv ruaj khov thiab qhov sib txawv tsis sib xws hauv koob. qhov no yog li ntawd qhov kev tiv thaiv yeej tsis poob rau xoom.

-Cov zis +ve mus rau lub hauv paus ntawm koj lub transistor (2n3055). transistor ua kom lub zog tam sim no mus rau qhov ntsuas tam sim no ntawm tus hloov pauv, hauv qhov no nws yog 2 A. Hauv kuv qhov xwm txheej, tus ntsuas hluav taws xob tsis tuaj yeem tuav cov dej ntau dua 10 mA, uas ua rau kuv siv lub transistor.

-Connect lub voltmeter nyob rau hauv parallel nrog rau cov zis coj.

-Tom qab txhua yam uas ua tiav, txuas lub xaim nrog lub taub hau ntsaws rau lub tshuab hloov pauv los ntawm kev hloov AC nrog qhov ntsuas. Rwb thaiv qhov sib txuas hauv qhov hloov nrog kua nplaum kub lossis kab xev hluav taws xob. Qhov hloov pauv tseem yuav ua lub fuse.

-Txhais kom txuas cov zis coj mus rau cov yeeb yaj kiab. Nws raug nquahu kom koj siv cov kais dej nrog cov npog.

Kauj ruam 3: Kaw nws

Kos cov chaw koj xav txiav ntawm koj lub thawv ntawv thiab txiav nws siv cov cuab yeej tig. Yog tias koj tsis muaj, koj tuaj yeem ua kom sov riam thiab hlais hla lub thawv yas zoo li butter (qhov ntawd yog qhov kuv tau ua). qhov kev tso kawm nyob ntawm koj lub npov thiab cov khoom.

Kom deb li deb tau, sim cais cov hloov pauv ntawm DC cov khoom. siv cov kua nplaum kub los yog kab xev hluav taws xob los tiv thaiv cov kab hluav taws xob thiab cov khoom siv.

Ib qho teeb meem kuv tau ntsib yog kev teeb tsa lub hwj chim. nws muaj cov txiv ntoo, tab sis cov xov me me heev; yas vaj huam sib luag ntawm lub thawv tau tuab heev. Txhawm rau daws qhov no, siv rab riam kub maj mam yaj me me ntawm cov yas los sab nraud. tom qab ntawd koj tuaj yeem siv cov cuab yeej thiab kaw cov txiv ntoo ntawm lub zog loj.

Kauj Ruam 4: Kev ceev faj

-Nco ntsoov tias TSIS TXHOB luv cov txiaj ntsig. Qhov no yuav siv lub nra rau ntawm Circuit Court thiab nws tuaj yeem kib.

-Txhua qhov txuas lub Hwj Huam ua ntej ua kev hloov pauv rau nws.
