A study on the DC distribution system for small scale residential buildings

摘要: Nowadays, most of electrical load that we use is suitable for DC instead AC. The portion loads to AC increasing dramatically. Also, environmentally friendly renewable energy sources such as photovoltaics and fuel cells produce DC. It means conversion could be effective with distribution compared because much potion power source are changed from Therefore, home a building has been attractive issue in research area. This paper deals the core technologies at small-scale residential composed converted appliances, grid-interactive converter regulating bus voltage, bidirectional battery interface, simulator. To prove test system, proposed devices converters built up loads. Many important configurations considerations explained facilities.
