A 5V 40A hloov fais fab mov nrog cov zis hluav taws xob tsawg (tsuas yog 2.4V) nrog lub suab nrov txawv txav tuaj yeem daws tau los ntawm kev hloov lub potentiometer. Kev tsom xam tshwj xeeb yog raws li hauv qab no:
Cov tsos mob txhaum cai thiab kev daws teeb meem pib: Lub zog hluav taws xob tso tawm hluav taws xob nyob deb ntawm tus nqi nominal (tsuas yog 2.4V), thiab lub suab nrov txawv txav tshwm sim tom qab hluav taws xob raug txiav tawm, qhia tias tej zaum yuav muaj luv luv Circuit Court, tsis zoo soldering, los yog tsis ua hauj lwm nyob rau hauv cov kev cai Circuit Court. Thaum pib hloov lub 250V 470μF loj capacitor tsis daws qhov teeb meem, qhia tau hais tias qhov teeb meem yuav tsis nyob rau hauv lub input filtering theem, thiab ntxiv kev soj ntsuam ntawm lub voltage tswj Circuit Court yog xav tau.
Cov kauj ruam kho tseem ceeb:
Polypotentiometer Function Verification: Siv lub tshuab ntsuas ntau los saib xyuas cov zis hluav taws xob thaum tib lub sijhawm kho tus thawj 1K potentiometer (tswj lub voj kev tawm tswv yim kom ruaj khov rau qhov tso zis hluav taws xob). Yog tias qhov hluav taws xob tsis hloov pauv thaum tig lub potentiometer, nws tuaj yeem txiav txim siab tias muaj kev sib cuag tsis zoo lossis tsis kam ua haujlwm, ua rau kev tawm tswv yim tsis ua haujlwm thiab tiv thaiv cov zis hluav taws xob los ntawm kev ncav cuag tus nqi.
Polypotentiometer Hloov: Tom qab hloov nrog lub potentiometer tshiab ntawm tib qhov tshwj xeeb (1K), kho thiab saib xyuas cov zis voltage. Yog tias qhov hluav taws xob rov qab mus rau 5V thiab lub suab nrov tsis zoo ploj mus, nws qhia tau hais tias tus thawj potentiometer qhov kev tiv thaiv kev tiv thaiv tau dhau los ua qhov txawv txav vim yog siv sij hawm ntev los yog ib puag ncig (xws li plua plav lossis oxidation), ua rau lub tswv yim Circuit Court ua haujlwm tsis zoo.
Kev soj ntsuam suab nrov: Tom qab lub hwj chim tsis ua hauj lwm, lub suab nrov txawv txav tuaj yeem tshwm sim los ntawm qhov xoob inductor lossis transformer core, lossis capacitor charging thiab tawm kev vibrations, tab sis nws muaj feem cuam tshuam rau Circuit Court oscillations los ntawm potentiometer malfunction. Thaum lub voj kev tawm tswv yim tsis ua tiav, lub transistor hloov pauv tuaj yeem ua haujlwm ntawm qhov txawv txav, ua rau cov khoom sib nqus vibrate. Hloov lub potentiometer rov qab kho lub voj voog mus rau qhov qub, thiab lub suab nrov txawv txav tau ploj mus, ntxiv xyuas qhov kev kuaj mob no.
Kho Cov Lus Ceeb Toom:
Kev Nyab Xeeb Ua Ntej: High-voltage capacitor muaj nyob rau hauv cov khoom siv hluav taws xob hloov. Tom qab fais fab tsis ua hauj lwm, tos tsawg kawg 5 feeb kom lawv tawm kom tsis txhob muaj hluav taws xob poob.
Cov txheej txheem kev khiav hauj lwm: Thaum siv cov hlau soldering los hloov cov khoom, ua tib zoo saib xyuas qhov kub thiab lub sij hawm kom tsis txhob muaj kev puas tsuaj rau PCB board lossis cov khoom nyob ib sab.
Component Matching: Potentiometers ntawm tib qho kev tiv thaiv thiab kev ntsuas hluav taws xob yuav tsum raug xaiv los xyuas kom meej cov lus qhia tsis sib xws hauv Circuit Court.
Summary: Nyob rau hauv cov ntaub ntawv no, lub potentiometer malfunction, ua rau lub voltage tawm tswv yim voj tsis, yog lub ntsiab yog vim li cas rau qhov tsawg tso zis voltage. Los ntawm kev hloov lub potentiometer thiab hloov kho nws, lub zog hluav taws xob tuaj yeem rov ua haujlwm sai sai. Thaum lub sij hawm kho, nws yog ib qho tsim nyog yuav tsum nkag siab txog lub hauv paus ntsiab lus ntawm Circuit Court thiab saib xyuas qhov tseem ceeb ntawm kev tswj xyuas cov khoom kom tsis txhob muaj qhov muag tsis pom kev hloov cov khoom siv xws li cov capacitors loj.
