报告简介

The use of sustainable sources for energy generation has been the focus of discussions between researchers, companies, governments and enthusiasts in the last decades. The popularity that theme achieved is usually justified by the associated ecological appeal, but it is also related to the need for diversification of the world energetic matrix and the advantages that smart grids bring to the energy conscious consumption.

Photovoltaic generation presents itself as one of the highlights in this context. Although it has been under study for almost two centuries (since the discovery of the photovoltaic effect in 1839), has gained emphasis over the last decades, accompanied by the development of several equipment for electronic energy processing. Are found today, photovoltaic systems in several areas: from small residential plants to large industrial facilities.

The connection of photovoltaic systems to the power grid network in residential applications is becoming a major segment of the growth in the market for sustainable energy, especially in the Europe, Asia and the United States. The connection of photovoltaic system to the power grid network has become regulated, encouraging its dissemination.

A trend in the processing equipment market photovoltaic solar energy is the so-called microinverter. By being able to connect a single module to the electrical network, it has advantages modularity and the initial cost of implementation.

The consolidation of this kind of equipment in the European, Asian and North American markets, makes it interest for academic work and is the theme of this seminar In our presentation will discuss: single and three-phase topologies with one or two stages, input high gain converter.
