Raws li Peb Paub tias lub hnub ci zog yuav yog yav tom ntej ntawm txhua yam khoom siv hluav taws xob, Tab sis siv lub hnub ci zog kom muaj txiaj ntsig peb xav tau me ntsis cov teeb meem hluav taws xob, Raws li peb paub txog Tsoos PWM raws li Hnub Ci lub charger nws yooj yim los tsim nrog rau tus nqi qis tab sis nws nkim ntau lub zog. li cua sov thiab Puas, t Hloov Siab Impedance Fais Fab rau qis dua, Hauv lwm MPPT tuaj yeem hloov pauv qhov kev tiv thaiv hluav taws xob kom qis Yog li MPPT raws cov tshuab hluav taws xob tuaj yeem yog Buck Boost Converter, Buck Converter Nqa Kev Hloov Siab Zoo.
Yog li Peb Yuav Ua Kom Tau Ib Qho Thiab txhawb kev hloov pauv rau MPPT.
Kauj Ruam 1: Ua haujlwm ntawm MPPT
Lub hauv paus tseem ceeb ntawm MPPT yog tias peb siv txhua lub zog ntawm lub hnub ci vaj huam sib luag kom them lub roj teeb thiab tsav lub zog, Feem ntau cov nyiaj txhawb nqa hloov pauv tuaj yeem ua rau pob los yog txhawb kev siv hluav taws xob kom nws tuaj yeem pab tau nyob rau hnub ci lossis hnub ci qis,
Kauj ruam 2: Schematic Daim duab
Cov Qauv no Raws Li Txoj Cai Tam Sim No PWM cuntroller UC3843 qhov no yog lub npe PWM uas muaj npe nrov heev.
Lub hwj chim lees txais 13 txog 27 volts thiab tsim tawm qhov hloov pauv tau. Topology yog SEPIC (ib leeg-xaus thawj qhov hloov pauv inductance), qhov kom zoo dua yog muaj peev xwm hloov pauv lossis nce nrog qhov tsawg kawg ntawm ib feem thiab ua haujlwm siab tshaj plaws. qhov hloov pauv no tuaj yeem siv rau hnub ci them tus nqi. SEPIC topology siv ob lub inductors, tab sis yog tias koj ob leeg lawv koj cov kev ua haujlwm nce mus.
Nta- Qhov hloov pauv no tuaj yeem muab cov zis tawm mus txog 4 Amps Ntawm 24v Thaum Tawm Ntawm 12volt. Cov qauv no tau tiv thaiv luv Circuit Court (0.01 ohm) Resistor yog lub luag haujlwm rau Qhov siab tshaj plaws tam sim no txwv, siv tus nqi qis rau qhov siab tshaj tam sim no Siv Jumper xaim rau qhov siab tshaj plaws tso zis tab sis nws saturates Mosfet.
Tub ntxhais-Feem ntau qhov nyuaj ntawm qhov hloov pauv no yog nws ua Transformer. Kuv siv tus lej N87 Los Ntawm Computer PSU, Kuv tsis paub cov khoom siv tseeb. Nws yog qhov txhab nyob rau hauv bifilar zam. Kuv siv Daim Kab Xev Hluav Taws Xob txhawm rau ntxiv qhov sib txawv nruab nrab ntawm ob ntu ntawm Transformer los tswj huab cua Gap, thiab muab qhov chaw ntawm epoxy tso rau hauv nws kom tsis txhob ua suab nrov. zauv systems. Nws los hauv pob 8 tus pin DIP, Nco tseg- Siv Cov Khoom Zoo Zoo Piv Txwv- Capacitor, Mosfet, Shotky Diode qhov no ua kom muaj txiaj ntsig zoo ntawm kev hloov pauv.
Kauj Ruam 3: Xeem
Koj Tseem Tuaj Saib Yeeb Yaj Kiab Kom Paub Cov Ntaub Ntawv Nws yog lus Askiv sub-title.
Nws tuaj yeem Tsav 3x22 watt teeb ntawm qhov ci ntsa iab.
Cons- Nws tsis tuaj yeem ua haujlwm tau zoo hauv qab 10v. Peb yuav sim daws nws hauv qhov haujlwm tom ntej yog tias koj muaj lub tswv yim txog nws koj tuaj yeem qhia nws nrog peb.
Kauj ruam 4: Txhua yam ua tiav
