Programmable electronic circuit breaker

Diplomska naloga opisuje razvoj programabilne elektronske varovalke za cestna vozila, s katero želimo v prihodnosti nadomestiti standardne elektro-mehanske varovalke s taljivo sredico. Predstavljena je osnovna teorija delovanja sistema v današnjih časih, ter predstavitev sistema po vgradnji naše rešitve. Programabilna elektronska varovalka je kombinacija digitalnega in analognega dela vezja. V prihodnje bo kot celota vključevala tudi računalniški programski vmesnik ter vmesnik med računalnikom in zgoraj omenjeno napravo. Precizno delovanje sistema je opisano spodaj, vendar želimo s to napravo zamenjati taljive varovalke, ki pregorijo pri določeni obremenitvi in so ključni del vsakega sistema, zato je bilo potrebno veliko časa posvetiti samim varnostnim funkcijam. Predstavljen izdelek sem razvijal za podjetje SG Automotive d. o. o., ki razvija in izdeluje izdelke, uporabljene v avtomobilih povsod po svetu.The diploma thesis is describing the development of the programmable electronic circuit breaker for motor vehicles, which in future will preferably replace the standard electro mechanical fuses. I presented the basic theory of how this system works today and how it will work after introducing our solution. The programmable electronic circuit breaker is a combination of the digital and the analog circuit. Ultimately, this system will also include a computer software and an interface between the computer and the presented device. The precise functioning of the system is described below, but as stated previously, our goal is to replace the standard fuses with this device. These fuses burn out at overload and while being the most important part of every system, we have to focus on implementing a reliable safety function. We developed the presented device for the SG Automotive d.o.o. company, which develops and produces products for various automotive industries around the world
