Nyob zoo, qhov no yog kuv thawj Instructables. Hauv Cov Lus Qhia no kuv yuav qhia qhov kuv tau ua qhov hloov pauv yooj yim rau lub zog 12 W LED teeb.

Lub voj voog no hloov pauv 12 V DC los ntawm roj teeb mus rau 220 V AC ntawm qhov ntau zaus vim tias nws tau siv tus tub sab nyiag los ua lub plawv hauv Circuit Court. Txij li nws cov zaus tso tawm yog siab (ib puag ncig 16-18 kHz - TSIS 50 Hz), koj tsuas tuaj yeem siv lub teeb pom kev (tshwj tsis yog lub teeb), tsis yog lwm yam khoom siv hluav taws xob. Nws tsim nyog siv rau thaum koj thaj av tau txais lub hwj chim tsis muaj zog.

Kauj Ruam 1: Schematic thiab Cheeb Tsam

Qhov no joule tub sab inverter yuav xav tau:

1. Perfboard lossis dotted PCB.
2. NPN fais fab transistor. Kuv siv TIP31c.
3. ib tug transistor heatsink.
4. Electrolytic Capacitor. 1 daim ntawm 220uF thiab 1 daim ntawm 2200uF nrog siab dua 12V qhov ntsuas hluav taws xob.
5. 1 tus qauv diode (1N4007), thiab 1 diode rov zoo (UF4007 lossis 1N4148).
6. Resistors. 1 220 Ohm, 1470 Ohm, thiab 3 12 Ohm 20 watt.
7. Transformer ferrite core, lossis lub nplhaib ferrite.
8. 0.2 hli thiab 0.7 hli hlau nplaum hlau.

Kauj Ruam 2: Tshem Tawm Qub Transformer Hlau Hlau

1. Ua kom sov cov tub ntxhais ferrite nrog cov hlau txuas kom txog thaum cov nplaum yaj thiab nws yooj yim rau disassemble.
2. Tev tawm daim kab xev npog cov hlau nplaum hlau.
3. tshem tag nrho cov hlau nplaum hlau tawm hauv cov tub ntxhais ferrit thiab npog yas.

Kauj Ruam 3: Cua Tshiab Hlau Hlau Hlau Raws Li Cov Qauv

Cov hlau nplaum hlau yog txheej nrog txheej txheej txha hniav laus. Kos qhov kawg ntawm cov hlau siv riam los tshem tawm cov txheej ua ntej yuav siv tas.

I. Cua thib ob winding siv 0.2 hli xaim

1. Muab cov hlua khawb rau cov hlau hlau ntawm lub hau yas hloov pauv.
2. cua 25 tig, thiab ntxiv txheej yas kab xev tom qab 25 txoj hlua.
3. Txuas ntxiv mus kom txog thaum nws mus txog 200 tig. Ntxiv ib txheej ntawm kab xev txhua 25 windings.
4. Tom qab 200 txoj hlua txuas mus txog, kos qhov kawg ntawm xaim thiab txuas rau cov hlau hlau tsis yog tus pin (2)
5. Npog nrog daim kab xev yas txhawm rau tiv thaiv kev so.

II. Cua qhov tseem ceeb winding. Muab cov xaim txuas rau tus pin, ntxiv 9 tig, thiab tom qab ntawd txuas lwm qhov kawg rau lwm tus pin

III. Cua cov lus taw qhia winding. Muab cov xaim txuas rau tus pin, ntxiv 9 tig, thiab tom qab ntawd txuas lwm qhov kawg rau lwm tus pin

IV. Muab cov tub ntxhais ferrite rov qab, kaw nws nrog daim kab xev yas

Kauj Ruam 4: Muab Cov Cheeb Tsam Tag Nrho rau ntawm Perfboard

Nws yog lub sijhawm los txhuam tag nrho cov khoom siv rau lub perfboard raws li cov txheej txheem. Hauv daim duab no kuv siv lub tshuab hloov pauv toroid nrog lub nplhaib ferrite, raws li kuv lub xwmfab transformers ferrite core tau poob tawg ua tej daim. cov txheej txheem winding thiab tus naj npawb ntawm tig yog tib txoj kev.

Kauj ruam 5: Xeem

Kuv siv kuv lub roj teeb 12 V scooter. Lub voj voog no kos txog 1 Ampere thaum ua lub zog 12 W LED teeb nrog lub ci ci tag nrho, zoo ib yam yog tias lub teeb tau siv los ntawm 220 V lub tsev hluav taws xob.

Yog tias koj xav txo qhov kev kos tam sim no, nce 12 Ohm resistor rau 16 lossis 20 Ohm. Lub teeb yuav dim me ntsis.

Lub inverter tseem tuaj yeem siv hluav taws xob 14 W lub teeb ci tab sis nws tsis zoo li lub LED txawm tias nws kos tib 1 Ampere. Nws kuj tseem tuaj yeem siv lub 12 W UV Germicidal Teeb ntawm qhov ci ci.
