Renewable energy, such as solar, is crucial to combating the environmental effects of fossil fuels. Some studies have proposed a step-up converter based on a conventional boost converter and a coupled inductor. This paper proposes a high step-up DC-DC converter designed for solar system applications. The interleaving method is used at the converter's input to reduce the input current ripple and increase the voltage gain. This converter has a high voltage gain and a low voltage stress on the semiconductor elements, while the conduction losses of the converter are reduced. The proposed converter with a power of 220 watts, an input voltage of 10 volts, and an output voltage of 120 volts is simulated in MATLAB software. Ultimately, the performance of the converter has been assessed through analysis and simulation. Furthermore, the converter's performance was compared with several similar topologies. The results and comparisons clearly demonstrate the effectiveness of the proposed converter.
