2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Hav hnub no hauv cov lus qhia no kuv yuav qhia koj li cas kuv tau tsim kuv thawj zaug txhua lub zog siv. Muaj ntau lub hwj chim muab cov vis dis aus hloov pauv hauv is taws nem. Ob peb ntawm cov yam ntxwv ntawm txoj haujlwm no tau hais meej hauv daim duab saum toj no.

Tam sim no ua ntej koj tsim txoj haujlwm no kuv xav coj qhov no rau koj daim ntawv ceeb toom tias kuv xav tsim lub zog siv hluav taws xob uas muaj ob qho tib si tsau thiab hloov pauv qhov hluav taws xob nrog rau kev nyeem tam sim no. Kuv tau ua txoj haujlwm tab sis kuv tsis tuaj yeem tau txais qhov nyeem tam sim no raug ntawm cov zaub. Thaum xub thawj kuv xav tias muaj qee yam tsis raug nrog kuv cov zaub lossis kev tawm tsam ntawm DPDT hloov pauv ua rau qhov ntawd. Tab sis sai sai no kuv pom tias Hloov Hloov lub zog siv hluav taws xob Kuv khaws los ntawm kuv lub PC tsis tuaj yeem muab qhov hluav taws xob tas mus li rau lub sijhawm ntev dua. Kuv tseem tsis tau paub meej tias qhov teeb meem tseeb yog dab tsi. Tab sis tom qab ntawd SMPS tau tag mus rau hauv coma thiab kuv tsis tuaj yeem sim qhov DIY fais fab mov. Tam sim no kuv yog tus neeg tub nkeeg thiab vim li no xaiv tsis qhib Lub Hwj Huam los kho qhov teeb meem. Hloov chaw kuv ua qhov yooj yim tsau ib qho rau kev siv ib ntus. Koj tuaj yeem pom qhov online yooj yim heev. Qhov laj thawj tsuas yog kuv tab tom sib qhia qhov no ntawm no yog qhia koj qee lub tswv yim li cas kuv tau ua qhov hloov pauv no + Cov Khoom Siv Hluav Taws Xob ruaj khov. Thiab qhov no yuav ua haujlwm rau koj yog tias koj khaws "PSU" Ua Haujlwm. Yog li cia saib cov txheej txheem tsim.

Kauj Ruam 1: Sau cov khoom siv

Cia peb saib txhua qhov khoom. Kuv tsuas yog sau lawv ntawm no ib ntawm ib qho. (Koj tuaj yeem xa cov duab saum toj no)

1. Ib qho qub SMPS (Hloov Hom Fais Fab Khoom)

2. Buck Boost converter

3. Voltage Current Meter Zaub

4. Ob Chav Ncej Ob Leeg (DPDT) Toggle Hloov

5. Hloov Hloov (Kuv tsis tuaj yeem pom cov khoom xav tau hauv kuv thaj chaw yog li kuv yuav tsum siv qhov no)

6. 10K Potentiometers nrog pob qhov rooj

7. Kev Sib Raug Zoo & Txiv tsawb txuas

8. Rocker Hloov

9. Cov Kws Cuam Tshuam

10. Cov Hluav Taws Xob Kub Kub rau Buck Boost Converter IC's

11. Coj thiab 220 Ohm resistor

12. MCB (tsis teb los tau)

13. USB/Micro USB chaw nres nkoj/DC Jack (yeem)

Nrog rau cov lus hais saum toj no koj tseem yuav xav tau qee yam cuab yeej.

Cov Cuab Yeej: Cov chaw nres tsheb Soldering, Cov raj cua sov ntsws, Cov tshuab laum, Hlau txiav, 2.5 hli xaim xaim xaim, Txau xim, Ntawv xuab zeb, thiab lwm yam

Kauj Ruam 2: Qib Voltage ntawm SMPS

SMPS muaj cov xov hlau sib txawv sib txawv sib txawv. Txhua lub xov hlau sib raug mus rau qib sib txawv. Cov duab saum toj no yuav muab tswv yim rau koj txog qib voltage.

Rau txoj haujlwm no peb yuav siv feem ntau ntawm cov xov hlau tshwj tsis yog -12 V (Xiav).

SMPS qhib thaum koj txuas lub xaim ntsuab rau xaim dub.

Nco tseg: Qee qhov SMPS muaj cov xim xim daj. Cov xaim ntawd xav tau txuas nrog 3.3 V cov khoom siv.

Kauj Ruam 3: Daim duab Circuit Court

Daim duab txuas rau txoj haujlwm no tau qhia saum toj no. Koj yuav tsis xav txuas txhua yam khoom ua ke yam tsis kuaj nws ua ntej. Yog li rau qhov ua raws thawj daim duab uas yuav qhia qhov yooj yim Hloov pauv Voltage ib feem ntawm qhov khoom siv hluav taws xob no.

Kuj nyeem tag nrho cov ntsiab lus ntawm daim duab tom ntej. Lawv yuav pab koj kom nkag siab txog kev sib txuas.

Kauj Ruam 4: Txhim Kho Cov Ntaub Ntawv Fais Fab

Nov yog qhov tseem ceeb uas kuv xav hais txog ntawm txoj haujlwm no. Tsim ib rooj plaub los ntawm kos tuaj yeem nyuaj qee zaum. Yog li ntawm no yog yam koj tuaj yeem ua tau. Yog tias koj muaj ob kab ntawm SMPS ces tsuas yog koom nrog lawv ua ke ib sab thiab txiav qhov chaw nruab nrab kom hla cov xov hlau thiab kom huab cua ntws los ntawm ib sab mus rau lwm qhov. Xa daim duab 3 rau qhov ntawd.

Tom qab ntawd ua qee qhov rau cov khoom sib txuas, hloov pauv thiab V-I zaub. Yog tias koj siv MCB ces txiav ib qho rau qhov ntawd ib yam.

Tam sim no pleev xim rau lub casing nrog qee cov tshuaj tsuag.

Tom qab ntawd nruab txhua lub tshuab hluav taws xob thiab kaw lub thawv.

Kauj Ruam 5: Ua Cov Kuaj

Lub zog hluav taws xob tsis ua tiav yam tsis muaj nws qhov kev soj ntsuam. Yog li cia ua khub nrog qee qhov 2.5 hli tuab tuab xaim hloov tau.

Siv ib sab kawg ntawm xaim mus rau tus kauv kauv thiab ntsia lwm qhov kawg rau tus txiv neej txuas.

Kuv kuj tau ntxiv 5V USB lub qhov (socket) rau lub hwj chim tsuas yog thaum kuv yuav tsum tau siv lub tshuab hluav taws xob 5 volts.

Kauj Ruam 6: Qhov Fais Fab Kawg

Kuv tau txuas ib daim duab saum toj no uas qhia tag nrho cov hloov pauv, pob qhov rooj thiab txuas txuas.

Kuj tseem muaj ob peb cov duab qhia pom qhov kawg Lub Hwj Huam Zoo li cas.

Vam tias koj nyiam txoj haujlwm no. Kuj ua raws kuv ntawm no kom pom kuv lwm txoj haujlwm. Yog li ntawd nws yog hnub no. Pom koj sai sai nrog lwm qhov haujlwm.
