Tig qhov hloov pauv ntawm lub ntsuas qhov ntsuas mus rau qhov ntsuas qhov ntsuas hluav taws xob thiab tom qab ntawd siv daim kab xev liab txhawm rau txhawm rau ntsuas qhov liab ntawm lub ntsuas cua thiab siv lub ntsej muag dub txhawm rau txhawm rau ntsuas qhov ntsuas dub ntawm lub ntsuas. Tig lub pob qhov rooj ntawm qhov hloov pauv tau thiab koj yuav tau txais DC qhov sib txawv los ntawm kwv yees li 1.24V txog 15V.

Kauj Ruam 19: Txheeb Xyuas

LM317 yog kho tau 3-davhlau ya nyob twg zoo tswj qhov muaj peev xwm muab tau ntau dua 1.5 A dhau qhov tso tawm qhov hluav taws xob ntau ntawm 1.2 V txog 37 V. Cov ntsuas hluav taws xob no tshwj xeeb tshaj yog siv tau yooj yim thiab xav tau tsuas yog ob sab sab tiv thaiv los teeb tsa qhov hluav taws xob. Ntxiv mus, nws ntiav cov neeg sab hauv tam sim no txwv, kaw cua sov thiab them nyiaj thaj chaw nyab xeeb, ua rau nws tseem ceeb tshaj tawm cov pov thawj.

Los ntawm cov txheej txheem peb tuaj yeem pom tias thaum 12AV qhov hluav taws xob tau thov rau T11 thiab T12, tus choj txuas hluav taws xob sib txuas ua ke ntawm plaub IN4007 diodes txiav AC rau DC, 0.1uF ceramic capacitor, C3 yog lub tshuab hluav taws xob hla uas ua lub luag haujlwm hauv kev txo qis rhiab heev rau input kab impedance. Lub tshuab hluav taws xob hluav taws xob C1 thiab C4 yog siv qhov ua kom lub zog hluav taws xob hloov pauv mus rau qib DC qhov ze. Lub davhlau ya nyob twg hloov pauv yuav hla dhau mus rau hauv av txhawm rau txhim kho ripple tsis lees paub. Lub tshuab hluav taws xob C5 tiv thaiv ripple los ntawm kev ua kom nrov nrov vim qhov tso zis hluav taws xob tau nce. Yog xav paub ntau ntxiv ntawm cov hluav taws xob hluav taws xob hauv lub tshuab hluav taws xob rectifier thov nyem rau koj tus nas thiab mus ntsib qhov blog no hauv tab tshiab.

IN4148 diode, D1 yog siv los tiv thaiv VCC los ntawm kev tso tawm los ntawm LM317 thaum lub sijhawm nkag luv luv. Lub diode, D2 yog siv los tiv thaiv lub tshuab hluav taws xob C5 tawm los ntawm LM317 thaum lub sijhawm luv luv. Thiab kev sib xyaw ua ke ntawm D1 thiab D2 tiv thaiv C5 los ntawm kev tso tawm los ntawm LM317 thaum lub sijhawm nkag luv luv. Txhawm rau kho qhov kho qhov hloov pauv tau RP1 koj yuav tau txais cov zis DC qhov hluav taws xob los ntawm kwv yees li 1.24V txog 15V.
