DC distribution systems and microgrids
2017The idea of merging variable sources with energy storage and controllable loads into flexible systems called microgrids (MGs) has been presented more than a decade ago [1]. MGs can operate autonomously or be grid-connected, and depending on the type of voltage in the point of common coupling (PCC), AC and DC MGs can be distinguished.

Nonisolated High Gain DC–DC Converter for DC Microgrids
IEEE Transactions on Industrial Electronics, 2018DC microgrids are popular due to the integration of renewable energy sources such as solar photovoltaics and fuel cells. Owing to the low output voltage of these dc power generators, high efficient high gain dc–dc converters are in need to connect the dc microgrid.
