Abstract

This thesis explores the innovative realm of wireless power transfer (WPT), with a specific focus on its application in railway electrification, an area not extensively addressed in the existing literature, particularly concerning dynamic motion analysis. The research introduces a 6 kW dynamic multiple-transmitter and single receiver WPT system tailored for railway vehicles, employing a parallel synchronous multiple LCL-S compensation topology.Comprehensive static and dynamic tests were conducted to evaluate the system's performance. In static testing, the system demonstrated remarkable DC-to-DC efficiency, reaching up to 94.73% with an output of 3.0 kW. Dynamic testing further confirmed the system's robustness, showcasing stable output and sustained efficiency, indicative of its potential for seamless integration into railway systems. Another aspect of the study involves electromagnetic field (EMF) testing to ensure the system's safety and compliance with established standards. The results from these tests provide crucial insights into the EMF emissions of the WPT system. Furthermore, the thesis delves into various application scenarios, illustrating the versatility of the WPT system in different railway contexts. From retrofitting existing railway systems to integration in newly constructed networks, the study showcases the broad potential of WPT technology in transforming railway electrification.
