2019 IEEE Third International Conference on DC Microgrids (ICDCM), 2019
A microgrid was developed as a modular “plug and play” system to accommodate both AC and DC loads up to a combined 125kVA total system power with a grid tie. A common DC bus configuration forms the backbone of the system, with bi-directional DC/DC and AC/DC power converters, allowing for a variety of renewable energy sources including PV arrays ...

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.
