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.

High voltage gain DC-DC converter for DC microgrid
2017 International Conference on Intelligent Computing, Instrumentation and Control Technologies (ICICICT), 2017A group of non-isolated DC-DC high voltage gain converters for Dc micro grid is discussed here. The combination of non-isolated boost interleaved converter helps to obtain high step up gain without operating in a high duty ratio conditions. Through interleaved manner, a continuous current can be drawn from the given input sources.
