Abstract	MARANGONI, Filipe. Single-Phase Inverters for Photovoltaic Grid Connec ted Systems. 2012. Dissertação (Mestrado em Engenharia Elétrica) – Programa de Pós-Graduação em Engenharia Elétrica, Universidade Tecnológica Feder al do Paraná. Pato Branco, 2012. This research presents a comparative study of singl e-phase transformerless grid connected inverters, employing photovoltaic generat ors. Initially is highlighted the increasing worldwide demand for electricity and the growth of the use of renewable sources, driving the development of these technologies. It is also prese nt d an overview of the photovoltaic decentralized power generation, including the major types of systems and their connection to the utility grid. In order to reduce the electricit y cost of photovoltaic generation, the elimination of low frequency transformer that conne cts the inverter to the grid, was presented as an interesting alternative. But associated with the direct inverter connection, leakage currents may arise due to the existence of parasiti c capacitances between the panel photovoltaic cell and the system ground. To avoid t hese problems, several modifications in the electronic circuit of the inverter have been pr oposed to eliminate variations in the inverter common mode voltage. This research evaluates some o f these topologies in order to define performance parameters that can serve as the basis for choosing a topology over the other for a set of specifications such as the installed power or the amplitude of grid voltage, among others.
