Abstract

Diplomski rad je podijeljen u četiri cjeline. Prvo je dan kratki i generalni opis PV/T sustava. Potom u drugom dijelu rada su opisani glavni dijelovi upravljanog PV/T sustava. Ovakav PV/T sustav se upravlja pomoću sinkronog silaznog pretvarača i algoritma za iskorištenje maksimalne snage fotonaponskog panela. Trošilo predstavlja baterija koja pokreće crpku za pumpanje vode. Nakon opisa glavnih dijelova načinjena je simulacija. Simulacija se može podijeliti u dva dijela. Prva simulacija je rađena u programima PLECS/MATLAB. Prikazuje djelotvornost P&O MPPT algoritma tj. da li panel daje maksimalnu snagu pri različitim vremenskim uvjetima (nadomješteno signalom Ir) te različitim parametrima. Druga simulacija je rađena u LTSpice-u gdje je prikazana djelotvornost sinkronog silaznog pretvarača sa realnim parametrima. Potom je opisan eksperimentalni sustav. Za eksperimentalan sustav je projektirana shema i štampana pločica sinkronog silaznog pretvarača i dodatnog upravljačkog dijela. Elektroničke komponente pretvarača su ispravno dimenzionirane i štampana pločica se može upotrijebiti za daljne projekte.

Abstract (english)

Thesis is divided into four parts. First, a brief and general description of the PV/T system is given. Then in the second part are described main parts of the controlled PV/T system. This PV/T system is controlled by a synchronous buck converter and an algorithm for maximum power utilization of photovoltaic panels. Load represents a battery that runs a pump for pumping water. The simulation is made after describing the main components. The simulation can be divided into two parts. The first simulation was done in the programs PLECS/MATLAB. It shows the effectiveness of P&O MPPT algorithm, that is whether the panel gives maximum power at different weather conditions (offset signal Ir) and various parameters. Another simulation was run in LTSpice which shows the efficiency of a synchronous buc converter with real parameters. Then, the experimental system is described. In the experimental system scheme and printed circuit board (PCB) of synchronous buck converter and an additional control units are designed. Electronic components of the inverter are correctly dimensioned and printed circuit board can be used for further projects.
