Abstract :
In recent years, the limitations of fossil fuel resources and the environmental issues, lead to a broad research in the field of renewable energies. Among renewable energy resources, solar cells, fuel cells, and wind turbines are more dominant. Therefore, the existence of a high step-up DC-DC convertor is necessary. In this paper, we focus on DC-DC converter with high voltage gain and output power of 200 watts. The proposed converter can convert the output voltage of one or more solar cells with low voltage to higher DC voltage and suitable for the input of a DC-AC converter. In this paper, the boost converter is combined with the coupled inductors and the capacitor-diode technique. This design aims to reduce the switching loss and conductive loss to improve the performance of the converter. The performance of proposed converter evaluated by simulation results and a prototype of the proposed converter with 200 W and 50 kHz. The results from simulation and the prototype depict the performance and accuracy of the proposed converter
