Abstract:V diplomskem delu so predstavljene posamezne komponente fotonapetostnih sistemov, podpore proizvodnji električne energije iz obnovljivih virov in osnove DC-DC ter DC-AC pretvornikov. Opisano je načrtovanje in preizkušanje enostopenjskega DC-AC pretvornika, ki se lahko uporablja kot omrežni razsmernik v sistemu sončne elektrarne. Za proženje stikal je uporabljena pulzno-širinska modulacija, ki je izvedena z uporabo digitalnega signalnega procesorja. Z namenom uvrstitve pretvornika v fotonapetostni sistem je določena prodajna cena izdelka, ki temelji na njegovi lastni ceni. Za potrebe določitve lastne cene je izvedena stroškovna analiza. V končni fazi je predstavljena še ekonomska upravičenost proizvodnje električne energije z omrežno priključenim fotonapetostnim sistemom, ki uporablja enostopenjski DC-AC pretvornik.

Title:SINGLE-STAGE DC-AC CONVERTER FOR PHOTOVOLTAIC SYSTEMS
Abstract:This report presents design and experimental testing of single-stage DC-AC converter for photovoltaic systems. Its main attribute is the fact that it generates an AC output voltage larger than the DC input, depending on instantaneous duty cycle. Output voltage is controlled with pulse-width modulation, which is done by using of a digital signal processor. With intention of placing single-stage DC-AC converter into a residential photovoltaic system the cost analysis of the converter is made and its selling price has been evaluated. Economic justification of electricity production with a micro photovoltaic power plant is rated in the final chapter. This work also presents the main components used in photovoltaic systems, basics of DC-DC and DC-AC converters and a short summary of legislation and support schemes for electricity produced from renewable energy sources in Slovenia.
Keywords:photovoltaic system, solar cells, support for renewable energy sources electricity, DC-DC converter, DC-AC converter, single-stage DC-AC converter, pulse-width modulation, converter design, cost analysis, costs, selling price, economic justification
