Abstract
At present, power shortage became a huge problem in many countries, due to cumulative load demand which cannot be met by Conventional Energy Power Generation. These challenging situations lead researchers to focus on non-conventional energy sources to extract Electric Power. In order to extract the electric power, DC–DC converters are adopted at the primary stage to increase the efficiency Power Conversion. This paper presents an assessment of current and future trend of non-isolated DC–DC converters (Such as Buck–boost, Cuk and Sepic) with various parameters and are analyzed using MATLAB Simulink. Based on the simulation result, the performances of non-isolated converters are evaluated and are helps to determine the suitable converter with a particular power rating for renewable energy based applications. In addition, the state space mathematical modeling of DC–DC converters are also presented which will be useful in the design of controllers for different non isolated DC–DC converters.
