Abstract

This article implements a best non-isolated DC-DCConverter for solar photovoltaic system-driven DC MicroGridapplications through high voltage gain methodology. At first, ahybrid boosting converter with bipolar voltage multiplier method isproposed and studied for photovoltaic-based DC MicroGrids. Butthe cost and functionality of this converter are a big problem. Toeradicate these problems with a proposed modified SEPICconverter and this converter is studied for producing high voltagegain. Formerly performance of hybrid boosting converter andmodified SEPIC converter are simulated in PSIM software. As afinal point, the simulation results are compared and verified thatthe modified SEPIC converter suits best for solar photovoltaicsystem-based DC Microgrids to provide essential power levels tothe residential electrical loads.
