A Review on Various DC-DC Converters for Photo Voltaic Based DC Micro Grids

Abstract

Currently the usage of power demand is increased by utility grids. In order to fulfilled the energy demand, tackle ecological concerns producing from the conservative energy sources, then researchers are moving towards the non- conservative (or) renewable energy resources integrated with DC micro grids to deliver power supply with improving system efficiency and especially cost reduction in distribution systems in a superior way. In non-conservative sources, solar energy is the cleanest and abundant green energy source available in nature. So, implementation of solar PV based DC micro grids technology is inexpensive, flexible, and energy-efficient to the end-users. But solar PV panels generate a low DC voltage. By using this low DC voltage as an input to the DC micro grids, definitely this grid does not serve any dc load properly. So, this problem can be erected with the help of DC-DC converters. The main motto of DC-DC converters is to properly produce the output voltage and ripple free output current to the dc load requirements. This paper gives the information regarding the various DC-DC converters applicable for solar PV based DC micro grids and at most, enlists the proposed MSC (Modified SEPIC Converter) is a best DC-DC converter for solar PV based DC micro grids based on the literature review discussed.
