Abstract: The rapid depletion of fossil fuels and the increasing demand for clean energy have promoted the use of renewable sources such as solar PV systems, fuel cells, and wind turbines. However, these sources usually produce low-voltage DC output, which is insufficient for applications like grid integration, battery charging, and electric vehicles. Therefore, an efficient step-up DC-DC converter is required to increase the voltage to the desired level.

This project presents the design of a High Step-Up DC-DC Converter with high voltage gain, improved efficiency, and reduced switching stress. The proposed converter uses a coupled inductor and voltage multiplier technique to achieve high voltage conversion with reduced power losses. Simulation using MATLAB/Simulink and hardware implementation will be used to validate the performance for renewable energy applications.
