2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Qhov no siv pob hloov pauv li 5V tso tawm kom them lub roj teeb (Li Po/Li-ion). Thiab Boost hloov pauv rau 3.7V roj teeb rau 5V USB tso tawm rau cov cuab yeej xav tau 5 V. Zoo ib yam li cov txheej txheem qub uas siv Lead Acid Battery ua lub zog khaws cia los ntawm PWM lossis MPPT maub los. Thiab muab rau 12V Cov Khoom Siv. Qhov Ib Qhov no tsuas yog siv Buck hloov pauv 12V (hnub ci vaj huam sib luag nominal voltage) kom ruaj khov 5V kom them lub roj teeb Li-Po/Li-ion, tom qab nruab hnub nrig. Hloov mus rau Boost hloov pauv lub roj teeb qhov hluav taws xob 4.2 (3.7 nominal voltage rau Li-Po thiab Li-ion) dua 5V rau cov cuab yeej siv zog 5V. (Koj tseem tuaj yeem siv 5V hauv Buck Converter thaum nruab hnub thaum lub roj teeb Li-Po/Li-ion tab tom them.  Nws yuav tsis muaj txiaj ntsig zoo li qub system (12V). Kuv tsuas yog ua qhov no vim tias kuv lub hnub ci vaj huam sib luag zog tsuas yog 15W thiab tsis txaus peev nyiaj los yuav MPPT lossis PWM them nyiaj rau 12V. thiab tsis txaus rau lub zog thov uas xav tau siab dua 50W.

(Nco ntsoov, lub kaw lus tsis muaj tus tswj hwm.)

Cov kab ke no yog rau cov hnub ci ci uas qis dua 30W thiab tsuas yog 12V nkaus xwb. (9V lub hnub ci vaj huam sib luag tseem yuav ua haujlwm).

Kuv Qhov Kev Qhia Tshwj Xeeb Input Solar Panel = 12V (18V)

Lub zog siv = 15 W

Lub sijhawm them = nyob ntawm koj lub hnub ci vaj huam sib luag lub zog thiab lub roj teeb lub peev xwm.

USB tso zis 1 (Buck converter) = 5V

USB Output 2 (Boost converter) = 5V

Hom roj teeb = nyob ntawm koj xaiv (Li-Po/Li-ion) 3.7 thiab lub peev xwm-Kuv yog Li-Po nrog lub peev xwm ntawm 3500mAh.

Ib qho taw tes:

Thaum txoj haujlwm tseem tab tom rau kev sim rau kev txhim kho thiab suav nws qhov ua tau zoo thiab seb nws puas tsim nyog nws. Nug kuv cov lus nug rau txoj haujlwm.

Kauj Ruam 1: Npaj Cov Khoom Siv

• Purfboard (Qhov Nruab Nrab)
• Hlau
• Leads Alligator Crocodile Ob Qhov Kawg Test Roach Clip Jumper Wire (Yeem rau kev sim)
• 2x USB chaw nres nkoj
• Cov hlau lead.

Hnub ci vaj huam sib luag -(pom zoo 20Watts siab dua, 12V)

• 1x TP4056 them thiab tiv thaiv Circuit Court rau Li-Po thiab Li-ion.
• 1x Li-Po/Li-ion roj teeb (nyob ntawm seb lub roj teeb koj xaiv thiab lub peev xwm)

Buck-Converter (Ib qho kuv siv)

• (1x) LM2576T (5V version, 3A)
• (1x) 100uH Inductor
• (1x) 100uF thiab (1x) 1000uF Electrolytic capacitors
• (1x) Schottky Diode
• (1x 1K resistor thiab LED me me) -tus xaiv

Nrog rau cov cuab yeej ntsuas

Digital/Analog Multimeter (Voltage thiab Tam sim no xav tau ntawm no los laij nws qhov ua tau zoo)

Kauj ruam 2: Ua raws li Circuit Schematic

Solder tag nrho cov khoom hauv PCB purfboard.

Nws yuav zoo dua kom luv Cov Ntaub Ntawv ntxiv thiab rho tawm Pins ntawm USB chaw nres nkoj rau Android Xov Tooj.

nco ntsoov hloov lub Boost hloov pauv kom tsis txhob dhau TP4056 thaum them lub roj teeb.

Yog tias koj lub hnub ci vaj huam sib luag lub zog qis dua li lub zog pom zoo, uas yog 20Watts saum toj no, koj yuav tsum txuas lub roj teeb nkaus xwb. vim tias lub zog muaj tsawg hauv koj lub hnub ci vaj huam sib luag lub zog. Piv txwv: 15Watts yog 0.83A, uas txhais tau tias yog koj li tam sim no.

Kauj Ruam 3: Lub zog thiab ntsuas lub Circuit

Yog tias Circuit ua haujlwm tau zoo, tom qab ntawv sim nws los ntawm kev siv dummy load zoo li 5W resistor hauv cov zis thiab ntsuas qhov hluav taws xob thiab tam sim no. zoo li daim duab no.

Ntsib Teeb Meem

- photovoltaic system - cov

Yog tias qhov hluav taws xob nkag (photovoltaic) hauv pob-hloov pauv dheev poob qis dua qhov nominal voltage ntawm PV thiab qhov hluav taws xob tso tawm. ces qhov teeb meem yuav tsum nyob ntawm daim ntawv no.

*lub nra hauv cov zis tau txuas nrog thiab rub ntau lub zog los ntawm PV.

*Tshav ntuj qis dua vim muaj pos huab, thiab lwm yam.

yog tias koj qhov teeb meem tsis nyob ntawm daim ntawv no, tawm lus tawm thiab kuv yuav teb nws.

Kauj ruam 4: Tiav lawm

Peb ua tiav

Koj tuaj yeem suav qhov ua tau zoo ntawm Buck-converter thiab Boost converter los ntawm cov qauv no.

Cov Hluav Taws Xob Tawm Tawm Tam Sim No

------------------------------------------- x 100% = Ua tau zoo

Cov tswv yim Voltage x Cov tswv yim tam sim no

Tej Yam Yuav Tsum Nco !! - Nco ntsoov hloov qhov kev sib txuas ntawm Roj teeb thiab Boost-Converter kom tsis txhob ua haujlwm ntau dua TP4056 thaum nruab hnub. tsuas yog siv rau hmo no.

- Nco ntsoov tias muaj lub roj teeb them thaum ntsuas qhov tam sim no thiab qhov hluav taws xob kom tau txais nws qhov ua tau zoo.

Qhov Zoo thiab Qhov Tsis Zoo

+ 5V ua haujlwm. Rau kev them nyiaj thiab siv daim ntawv thov uas xav tau 5V- Tsis yog rau daim ntawv thov uas xav tau 12V/9V.

+ Tus nqi ua haujlwm tau zoo txaus. (Kuv yog 70% hauv kev hloov pauv phaus thiab 68% hauv Boost hloov dua siab tshiab) (Me ntsis siab dua yog tias koj siv qhov twb tau tsim tus qauv lawm.)

- Qhov ua tau zoo yuav poob yog tias cov tswv yim ntawm cov khoom siv hloov pauv poob. Vim cov zis kos lub zog.

+ Qhov system pheej yig

- Cov kab ke tsis muaj Tus Tswj (los saib xyuas lub roj teeb thiab hnub ci them nyiaj xwm txheej thiab kev tiv thaiv)

+ Ua tau yooj yim yog tias yuav qhov kev tsim kho uas twb tau ua tiav lawm thiab pob nyiaj siv.

Ib yam los taw qhia

Qhov txwv tam sim no tso tawm ntawm tus nqi-hloov pauv yog vam khom koj lub hnub ci vaj huam sib luag lub zog (Watts). Kuv lub hnub ci vaj huam sib luag lub zog yog 15 Watts, uas txhais tau tias kuv txwv rau tam sim no ntawm 0.75A thaum txuas rau lub charger. Qhov no yog vim li cas kuv pom zoo rau lub hnub ci vaj huam sib luag uas tsawg kawg siab dua 20W.

Xav tias tawm tswv yim yog tias koj muaj lus nug txog qhov project.

Yog tias koj ua koj tus kheej Photovoltaic 5V System. thov qhia.

Koj tuaj yeem ua raws kuv ntawm ib qho kev tshaj xov xwm. Yog li koj tuaj yeem ua tau
