摘要：
Aiming at the on-board power supply requirements of high-speed maglev trains in economy and reliability in narrow spaces, utilizing the coupling magnetic circuit, electrical performance simulation, and design optimization, a new type of transmitter, a non-contact power supply system (inductive power supply, IPS), is proposed, which features a multi-turn coil at the transmitting end, no magnetic core, and pickup ends similar to a double U-shaped coupled magnetic. First, according to the power supply requirements of high-speed maglev trains, the main parameters of each device are determined through theoretical calculations, and the IPS system design plan is completed. Then design and simulation analysis of the coupling magnetic circuit is conducted, including the use of Maxwell software to perform 3D simulation analysis on various coupling magnetic circuits, determining the optimal design scheme of the coupling magnetic circuit, and three-dimensional electromagnetic simulation to obtain the mutual inductance between the pickup device and the ground transmitting coil. Next, electrical performance simulation analysis is conducted with the use of Matlab software to establish an electrical simulation model of the IPS system, simulate the transmission power and efficiency of the IPS system, and determine the compensation device, ground inverter power supply and DC/DC parameters according to the power supply requirements. Finally, the 150 kW magnetic-field coupling contactless power supply system was developed and deployed on the maglev prototype test line. The on-site EMC (electromagnetic magnetic compatibility) performance and electrical performance test verification was completed. The transmission power exceeds 150 kW and the efficiency is 92%, achieving the expected objectives of the project Copyright ©2022 JOURNAL OF SOUTHWEST JIAOTONG UNIVERSITY. All rights reserved.
