Single-Phase H-Bridge Inverters and MPPT Algorithms

U radu se objedinjuje domena automatike, energetske elektronike i fotonaponskih sustava u svrhu izrade modela MPPT modula, odnosno provjera djelotvornosti metoda za praćenje točke maksimalne snage. Rad započinje uvodom u fotonaponske sustave i opisom postupka dobivanja električne energije iz sunčevog zračenja i načinom funkcioniranja pretvarača s MPPT algoritmom. Nakon toga slijedi opis različitih indirektnih i direktnih metoda te problema postizanja točke maksimalne snage. U zadnjem poglavlju se nalazi simulacija poboljšanja faktora snage u programu Plecs.This paper combines the domain of control systems, power electronics and photovoltaic systems to create a model of an MPPT module and test algorithms for maximum power point tracking. Paper analyzes photovoltaic modules and process of converting sun radiation in usable electrical energy and how MPPT algorithm operates in frame of sophisticated photovoltaic systems. After that, various indirect and direct methods are described along with problem related with obtaining maximum power point. In last chapter, simulation of improvement of fill factor is elaborated, and shown in software Plecs
