"Joule Thief" yog qhov yooj yim txhawb hluav taws xob Circuit Court. Nws tuaj yeem nce qhov hluav taws xob ntawm lub zog los ntawm kev hloov pauv qhov tsis tshua muaj hluav taws xob teeb liab mus rau hauv qhov ua kom nrawm nrawm ntawm qhov siab dua. Koj feem ntau pom cov kev siv hluav taws xob zoo no siv hluav taws xob LED nrog lub roj teeb "tuag", tab sis muaj ntau qhov muaj peev xwm thov tau rau lub Circuit Court zoo li no.

Kauj Ruam 2: Circuit & Piav Qhia
Joule Thief yog tus kheej-oscillating voltage booster. Nws yuav siv lub teeb liab qis tsis tu ncua thiab hloov nws mus rau hauv cov khoom siv hluav taws xob ntau zaus ntawm qhov siab dua. Nov yog qhov Joule Thief yooj yim ua haujlwm, ib qib zuj zus:
1. Thaum pib transistor tawm.
2. Ib qho hluav taws xob me me dhau los ntawm tus tiv thaiv thiab thawj kauj rau lub hauv paus ntawm transistor. Qhov no ib nrab qhib rau cov neeg sau-tso tawm channel. Tam sim no hluav taws xob tuaj yeem taug kev los ntawm cov kauj thib ob thiab los ntawm cov khoom siv-emitter channel ntawm transistor.
3. Qhov nce nqi hluav taws xob los ntawm cov kauj thib ob ua rau muaj qhov sib nqus sib nqus uas ua rau muaj hluav taws xob ntau dua nyob hauv thawj lub kauj.
4. Cov hluav taws xob induced thawj kauj nkag mus rau hauv lub hauv paus ntawm lub transistor thiab qhib lub channel collector-emitter txawm ntau dua. Qhov no tso cai txawm tias muaj hluav taws xob ntau dhau los ntawm cov kauj thib ob thiab los ntawm cov khoom siv-tso tawm channel ntawm transistor.
5. Kauj Ruam 3 thiab 4 rov ua dua nyob rau hauv cov lus tawm tswv yim kom txog thaum lub hauv paus ntawm transistor tau saturated thiab cov khoom siv-emitter channel tau qhib siab. Cov hluav taws xob taug kev los ntawm cov kauj thib ob thiab los ntawm cov transistor tam sim no yog qhov siab tshaj plaws. Muaj ntau lub zog tsim nyob hauv thaj chaw sib nqus ntawm lub kauj thib ob.
6. Txij li thaum hluav taws xob nyob rau hauv lub kauj thib ob tsis nce ntxiv, nws nres inducing hluav taws xob hauv thawj kauj. Qhov no ua rau hluav taws xob tsawg dua mus rau lub hauv paus ntawm transistor.
7. Nrog hluav taws xob tsawg dua mus rau lub hauv paus ntawm transistor, cov khoom siv-emitter channel pib kaw. Qhov no tso cai rau hluav taws xob tsawg dua los ntawm kev sib tw zaum ob.
8. Kev poob qis ntawm cov nqi hluav taws xob hauv cov kauj thib ob ua rau muaj qhov tsis zoo ntawm cov hluav taws xob hauv thawj kauj. Qhov no ua rau muaj hluav taws xob tsawg dua mus rau lub hauv paus ntawm transistor.
9. Kauj Ruam 7 thiab 8 rov ua dua nyob rau hauv cov lus qhia rov qab kom txog thaum yuav luag tsis muaj hluav taws xob hla lub transistor.
10. Ib feem ntawm lub zog uas tau khaws cia rau hauv qhov chaw sib nqus ntawm cov kauj thib ob tau ntws tawm. Txawm li cas los tseem tshuav ntau lub zog khaws cia. Lub zog no xav tau mus rau qhov chaw. Qhov no ua rau qhov hluav taws xob ntawm qhov tso tawm ntawm lub kauj kom nrawm.
11. Kev tsim hluav taws xob tsis tuaj yeem hla lub transistor, yog li nws yuav tsum hla lub nra (feem ntau yog LED). Qhov hluav taws xob ntawm cov zis ntawm cov kauj tsim kom txog thaum nws mus txog qhov hluav taws xob qhov twg tuaj yeem hla mus rau qhov thauj khoom thiab yuav ploj mus.
12. Lub zog tsim los mus dhau ntawm lub nra hauv qhov loj loj. Thaum lub zog tau ploj mus, lub Circuit Court tau rov pib ua haujlwm tau zoo thiab pib tag nrho cov txheej txheem ib zaug ntxiv. Nyob rau hauv ib txwm Joule Thief Circuit txheej txheem no tshwm sim 50, 000 zaug hauv ib pliag.
Kauj Ruam 3: Cua Toroid
Kev hloov pauv hauv Circuit Court yog ua los ntawm cov xaim hlau nyob ib ncig ntawm ferrite toroid. Cov toroids no tuaj yeem yuav los ntawm cov khoom siv hluav taws xob lossis lawv tuaj yeem khaws los ntawm cov cuab yeej hluav taws xob qub xws li cov khoom siv hluav taws xob.
Nqa ob daim nyias nyias insulated xaim thiab qhwv lawv ib ncig ntawm lub ntsej muag 8-10 zaug. Ceev faj tsis txhob sib tshooj ntawm cov xov hlau. Ua kom cov xov hlau sib nrug sib nrug kom ntau li ntau tau. Txhawm rau tuav cov xov hlau nyob hauv qhov chaw thaum kuv tab tom tsim qauv, Kuv qhwv lub toroid hauv kab xev.
Thiab tom qab ntawd koom nrog ob txoj kab xim sib txawv ntawm ob qho kawg ua ke raws li qhia hauv duab & xa cov vis dis aus kom nkag siab zoo dua.
Kauj Ruam 4: Kev Sib Txuas
ua raws li cov lus hais saum toj no thiab muab cov positvive ntawm tus coj coj los sau rau ntawm transistor & tsis zoo rau tus emitter & 1 k ohm rau lub hauv paus ces ib qho ntawm cov hlau ib leeg ntawm toroid rau tus sau & lwm yam rau 1k resistor raws li qhia hauv duab & yees duab thiab txuas cov xaim mus rau tus xa hluav taws xob tom qab ntawd txuas +ve ntawm lub roj teeb rau ob qho ua ke sib txuas xov tooj cua ntawm toroid & -v lub roj teeb mus rau xaim txuas nrog rau emitter.
Kauj Ruam 5: Kauj Ruam Kawg
Tom qab qhov no ua qhov no tas mus li ntawm pcb nrog rau qhov hloov pauv kom nws qhib lossis tua thiab rov siv koj lub qub AA roj teeb hauv koj lub teeb nyem me me ua nrog joule tub sab nyiag.
Yog tias muaj teeb meem nrog Circuit thiab lwm yam Tom qab ntawd xa vudeo kom nkag siab zoo dua.
Txaus siab rau ua koj tus kheej joule tub sab & rov siv koj cov roj teeb AA qub.
