Abstract:Namen diplomske naloge je bil izdelati solarni polnilnik svinčenih akumulatorjev s sledenjem točke največje moči (Maximum Power Point Tracking – MPPT). Polnilnik je zasnovan modularno, kar zagotavlja nižjo ceno ter hitrejši razvoj posamičnih komponent. Posvetili smo se delovanju integriranega vezja LT3763 in prikazu trenutnih parametrov polnilnika. Za prikaz trenutnih parametrov polnilnika je uporabljen mikrokrmilnik ATmega328 s prikazovalnikom s tekočimi kristali (LCD), vezje LT3763 pa služi regulaciji polnjenja. Za projektiranje je bila uporabljena odprtokodna ali brezplačna programska oprema. Delovanje polnilnika je bilo preverjeno s pomočjo simulacije s programskim paketom LTspice. Tiskana vezja so narisana kar se da enostavno za sestavljanje, vendar ne na račun poslabšanja termičnih in električnih lastnosti. Po končani izdelavi tiskanih vezij je sledil preizkus polnilnika.

Title:SOLAR BATTERY CHARGER
Abstract:The objective of this thesis was to create a solar charger for lead-acid batteries with maximum power point tracking (MPPT) capacity. The design of the charger is modular, providing for a lower price and more rapid development of individual charger components. Furthermore, we concentrated on the operation of the LT3763 integrated circuit as well as the display of the current charger parameters. To display current parameters, ATmega328 microcontroller and a LCD screen were used. While the LT3763 integrated circuit was used for controlling the charging. The solar charger controller was designed using open-source software and freeware. After having performed the necessary calculations, charger operations were simulated in order to predict operation. Printed circuit boards (PCBs) were designed as simple as possible to facilitate assembly, but not at the cost of deterioration of thermal and electric properties. After designing the PCBs, the completed solar charger for lead-acid batteries was thoroughly tested.
Keywords:charger, DC-DC converter, microcontroller, photovoltaic module, MPPT
