Ob peb xyoos dhau los, Julian Ilett tsim tus thawj, PIC microcontroller raws "PWM5" hnub ci tus nqi tswj. Nws kuj tau sim nrog Arduino raws tus qauv. Koj tuaj yeem pom nws cov vis dis aus ntawm no:

raws li Julians cov txheej txheem, arduined.eu tsim qauv me me, raws li 5V, 16MHz Arduino Pro Mini:

Tom qab kuv twb tsim thiab tsim ob lub MPPT pob hnub ci them nyiaj, kuv xav sim qhov kev tsim qauv yooj yim heev no.

Kauj ruam 1: Teeb duab Schematic

Cov txheej txheem yog raws li Julians txhais tes kos ib qho. Kuv sim ua kom nkag siab yooj yim li sai tau. Nws tseem yuav yog lub hauv paus rau PCB kom raug.

Cov dav dav dav dav yog lub hauv paus rau PCB txheej txheem no. Cov ciav hlau yog ib sab thiab dav heev. Qhov no tso cai rau koj txheeb koj cov laug cam yooj yim, yog tias koj tsis xav xaj lawv los ntawm cov chaw tsim khoom.

Kauj Ruam 3: Npaj Pawg Thawj Coj

Ua ntej kuv xaj cov laug cam, Kuv xav txheeb xyuas qhov tsim ntawm ib daim qauv ntawm pawg thawj coj. Nws loj yog 0.8 x 1.4 Ntiag.

Kauj ruam 4: Populating Board

Vim tias pawg thawj coj yuav tsum muaj qhov loj ib yam li Pro Mini, cov khoom siv tau nyob ze ua ke. Tau kawg peb kuj tseem tuaj yeem siv cov khoom SMD, tab sis kuv xav khaws qhov tsim raws li DIY tus phooj ywg li sai tau. Cov npe ntawm cov khoom tuaj yeem pom ntawm cov txheej txheem. Txhua tus tiv thaiv yog 1/4 Watt loj.

BTW: Nov yog kuv thawj qhov kev sim ua kom tsis muaj hlau lead. Yog li nws tuaj yeem saib huv;-)

Vim tias kuv xav khaws lub zog siv tsawg li sai tau (nws nyob ib puag ncig 6mA), Kuv tau siv 3.3V, 8MHz version ntawm Arduino Pro Mini. Yog li vim tias 3.3V (hloov 5V) khoom, Kuv tsis paub tseeb, yog tias lub twj tso kua mis yuav tuaj yeem tsim hluav taws xob qhov rooj xav tau rau IRF3205 MOSFET. Yog li kuv tau sim me ntsis nrog PWM sib txawv sib txawv thiab cov twj tso kua mis. Raws li koj tuaj yeem pom, qhov ntsuas hluav taws xob txog 5.5V tsis txaus los tsav qib MOSFET uas tsis yog-logic. Yog li kuv txiav txim siab siv IRLZ44N. Qhov no yog qhov hu ua logic qib MOSFET thiab ua haujlwm zoo nrog 5V.

Kauj Ruam 6: Siv cov khoom seem thiab Cov Hluav Taws Xob

Tom qab ntawd nws yog lub sijhawm los muab cov khoom seem txuas ntxiv nrog rau cov xov hlau thiab sab nrauv tiv thaiv sab nraud. Cov diode no tseem ceeb heev! Nco ntsoov, tias nws muaj peev xwm tswj hwm koj qhov siab tshaj tam sim no.

Vim tias cov software qub yog me ntsis koj ua li cas, Kuv txiav txim siab sau kuv tus kheej. Koj tuaj yeem rub nws (thiab Eagle PCB cov ntaub ntawv ntxiv rau Gerbers) ntawm kuv GitHub. Qhov txuas yog qhov kawg ntawm Cov Lus Qhia no.

Ib kauj ruam tseem ceeb yog txhawm rau txheeb xyuas qhov hloov pauv ntau tshaj plaws ntawm Julians MOSFET tus tsav tsheb Circuitry. Raws li koj tuaj yeem pom, 15kHz zoo li txaus ntshai (ntsuas ntawm MOSFET rooj vag) thiab yuav ua rau muaj cua sov ntau. 2kHz ntawm qhov tod tes zoo li siv tau. Koj tuaj yeem pom qhov sib txawv hauv cov vis dis aus ntawm thawj nplooj ntawv ntawm kab lus no.

Txhawm rau ntsuas qhov yuav tsum tau ua, Kuv tau siv kuv qhov pheej yig DSO201 hnab tshos oscilloscope, lub ntsuas qhov ntsuas thiab DIY Arduino lub zog ntsuas ntsuas.

Yog li, qhov xaus ntawm txoj haujlwm me me no yog dab tsi? Nws ua haujlwm zoo, tab sis tau kawg nws tsis tuaj yeem siv rau lub roj teeb lub npe qis dua 12V. Tsawg kawg nws yuav tsis muaj txiaj ntsig zoo rau qhov no, vim tias nws tsuas yog PWM them nyiaj ntau dua li hloov pauv phaw. Nws kuj tsis muaj MPPT taug qab. Tab sis rau nws qhov loj nws zoo heev. Nws kuj tseem ua haujlwm nrog cov hnub ci ci me me lossis nrog lub hnub ci ci heev.

Thiab tau kawg nws yog kev lom zem heev los tsim qhov no. Kuv kuj nyiam ua si nrog kuv oscilloscope thiab kom pom lub MOSFET tsav tsheb Circuitry.

Kuv vam tias, Cov Lus Qhia Me me tau pab rau koj. Kuj tau saib kuv lwm cov yeeb yaj kiab hluav taws xob ntawm kuv li YouTube channel.
