The increasing electricity demand is being met by photovoltaic energy conversion. Rural areas can be powered by energy from renewable energy sources when used in conjunction with existing power lines. Grid-connected photovoltaic systems have emerged widely, due to the advancement in DC-DC converter topology and inverter control techniques. The appropriate selection and operation of the DC-DC converter stage determines the efficiency of supplying power to the grid. Therefore, the efficiency of existing DC-DC converter topologies needs to be carefully analyzed. The conversion and design of high-gain low-power (HGLP) DC-DC converters, that can be used in solar photovoltaic supply systems are assiduously reviewed. For DC grids/microgrids, the basic characteristics and possibilities of the connection obtained from the topologies are pivotal. Different HGLP topologies has been reviewed and their performance in terms of voltage gain, number of components and application has been analyzed in this work.
