Abstract

Postoje brojne aplikacije gdje je potrebno osigurati više razina napona. Situacija se posebno komplicira ukoliko se želi napraviti akumulatorsko napajanje koje se planira napajati iz više izvora. U ovom radu će biti objašnjen proces definiranja specifikacija, projektiranja automatskog odabira koji ulaz će puniti akumulator, punjača olovnog akumulatora s jednostavno podesivim postavkama poput odabira nom. napona solarnog panela i maksimalne struje punjenja, sve potrebne zaštite, poput zaštita reverznog priključivanja, prepunjenja, prepražnjenja i prekostrujne zaštite, i izlaznih pretvarača koji generiraju sve standardne napone od 1.8V do 24V. Na kraju će biti odrađena testiranja svih sklopova kako bi se utvrdila njihova funkcionalnost te kvaliteta.

Abstract (english)

There are countless applications where multiple voltages are needed. Things get especially complicated if we want to make it battery powered and want multiple charging sources. In this paper we will walk through the process of defining the device specifications, designing automatic battery charger input switching, lead-acid battery charger with easily settable solar panel selection and max. charge current, all needed protection features, such as reverse polarity, overcharge, overdischarge and overcurrent protection, and output voltage converters that generate all standard voltage levels from 1.8V up to 24V. Finally, every circuit will be tested to determine if it functions as designed and judged on its quality.
