Abstract

With the acceleration of urbanization and the increase of public transportation demand, rail transit has been widely used as an efficient and environmentally friendly mode of transportation. As the core of rail transit traction system, power electronic technology plays an important role in improving train performance, reducing energy consumption and ensuring operation safety. This paper describes the basic knowledge of power electronics technology, including the principle, control strategy of various converters and their application in the traction system of rail transit. The application principle of power electronic technology in rail transit traction system is discussed. However, this paper also points out some problems that power electronics technology faces in rail transit traction systems, including technical application challenges, system reliability and safety challenges, economic and cost considerations, standardization and interoperability issues. To solve these problems, this paper puts forward corresponding countermeasures, such as strengthening technological innovation and optimization, improving system reliability and security, carrying out economic and cost-benefit analysis, and promoting standardization and interoperability construction. Finally, this paper summarizes the research results and looks forward to the future research direction.
