Video: Cov Khoom Siv Hluav Taws Xob yooj yim & Kev Ntseeg: 7 Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27
Hauv qhov haujlwm no kuv yuav qhia koj yuav ua li cas thiaj ua rau koj tus kheej lub hwj chim siv cov khoom siv yooj yim. Kuv yuav npog qhov kev xav yooj yim ntawm Transformers, kho kom raug thiab kev tswj hwm.
Kauj ruam 1: Hloov pauv
Qhov hluav taws xob hauv tebchaws Askiv thiab European lub tebchaws yog 230v. Qhov hluav taws xob no siab dhau los siv rau ntau daim ntawv thov yog li nws yuav tsum tau txo qis. Koj siv lub tshuab hloov pauv kom txo qhov hluav taws xob. Kuv tau suav nrog cov tswv yim thiab tso tawm nthwv dej rau qhov hloov pauv. Hauv qhov no tus hloov pauv txo 240V mus rau 40V.
Kauj ruam 2: Rectification
Thaum koj tau txo koj qhov hluav taws xob AC los ntawm kev siv lub tshuab hluav taws xob koj yuav raug tso nrog qhov qis dua AC fais fab mov. Cov kab hluav taws xob feem ntau siv DC (ncaj qha tam sim no) txhawm rau kom tau txais DC los ntawm AC cov khoom siv koj yuav xav tau kho nws. Kuv tau suav nrog qhov piv txwv ntawm nthwv dej kom koj nkag siab zoo tias nws zoo li cas.
Kev kho dua tshiab yog ua tiav siv diodes. Koj tuaj yeem siv ib qho diode rectifier lossis tus choj txuas tag nrho. Ib qho diode rectifier yog ib nrab yoj kho qhov no txhais tau tias nws tsuas yog muaj qhov zoo ntawm nthwv dej tab sis nws yuav ploj qhov tsis zoo ntawm nthwv dej.
Kev kho kom yoj tag nrho siv 4 diodes thiab yuav "ntxeev" qhov tsis zoo ntawm nthwv dej yog li koj yuav xaus nrog qhov nthwv dej zoo uas tsis muaj qhov khoob ntawm qhov zoo ib yam li ib nrab yoj rectifier yuav.
Rau ib nrab nthwv dej kho koj siv 1 diode thiab rau tag nrho yoj rectifier koj siv 4 diodes. Kev teeb tsa rau ib nrab tus choj thiab tag nrho tus choj kho qhov muag tau qhia hauv qab no.
Kauj ruam 3: Smoothing
Tam sim no koj tau kho koj li AC tam sim no yuav tsum tau ua kom du. Smoothing hais txog kev noj cov yoj uas tau kho thiab tuav cov khoom tawm mus rau qhov chaw siab tshaj ntawm nthwv dej.
Txhawm rau ua kom lub teeb liab AC raug teeb tsa koj siv lub capacitor. Kuv tau suav nrog daim duab hluav taws xob los qhia seb koj yuav tso lub capacitor rau hauv Circuit.
Kauj Ruam 4: Kev Tswj
Tam sim no koj muaj DC qhov hluav taws xob nws yuav tsum tau nqis mus rau qhov ntsuas qhov tseeb. Koj tuaj yeem siv tus tswj hwm los txo qhov hluav taws xob DC. Cov tswj hluav taws xob tuaj yeem tuaj yeem hloov pauv ntau yam los ntawm qhov hluav taws xob ruaj khov mus rau qhov sib txawv ntawm qhov hluav taws xob.
Kauj Ruam 5: Kawg Circuit Court
Tam sim no tsuas yog ua ke txhua qhov thiab koj yuav muaj DC lub zog siv.
Kauj Ruam 6: Kev lees paub
Kuv ua tsaug PCBWay & LCSC Electronics rau kev koom tes.
PCBWay yog qhov kev pabcuam pheej yig thiab ntseeg tau uas koj tuaj yeem tau txais koj li PCBs tsim. Txhua lub PCBs yog qhov ua tau zoo thiab cov kws ua haujlwm tau txais txiaj ntsig zoo. Sau npe hnub no thiab tau txais $ 5 zoo siab txais tos. Txheeb xyuas lawv lub khw khoom plig thiab saib Gerber.
LCSC Electronics Yog Tuam Tshoj tus ua cov khoom siv hluav taws xob faib khoom. LCSC muag ntau yam khoom siv hluav taws xob zoo ntawm tus nqi qis. Nrog ntau dua 150, 000 ntu hauv Tshuag lawv yuav tsum muaj cov khoom koj xav tau rau koj txoj haujlwm tom ntej. Sau npe hnub no thiab tau txais $ 8 tawm ntawm koj thawj zaug lossis
