Abstract
With the increasing global energy demand and enhanced environmental protection awareness, renewable energy has become a critical approach to addressing energy crises and environmental issues. Power electronic devices play an indispensable role in improving the efficiency, stability, and reliability of renewable energy systems. This study aims to investigate the application of power electronic devices in renewable energy sources such as solar and wind power. By analyzing the characteristics of different types of power electronic devices and their application scenarios in the generation, transmission, and distribution of renewable energy, this research employs a combination of theoretical analysis and simulation experiments for in-depth exploration. The results indicate that advanced power electronic devices, such as IGBTs and SiC MOSFETs, can significantly enhance the conversion efficiency of renewable energy systems, reduce losses, and effectively improve power quality. Particularly in distributed generation systems, grid-connected inverters based on novel power electronic devices have achieved efficient and stable energy conversion and transmission, providing technical support for high-proportion renewable energy integration into the grid. Innovatively, this study proposes selection principles and optimized configuration schemes for power electronic devices suitable for different types of renewable energy systems, which not only improve the overall system performance but also lay a solid foundation for the large-scale development and utilization of renewable energy in the future, thereby advancing the progress of clean energy technology.
