摘　　要：当磁浮列车靠近站台时,直线发电机产生的电能虽然能继续牵引列车前进,但不足以同时满足车载设备的用电需求。传统的接触式供电方式存在安装维护成本高、带电导体暴露等问题。无线供电技术能够消除传统供电方式的线缆连接,使磁浮列车摆脱机械接触,提高列车辅助供电系统的安全性、经济性和环境适应能力。文章针对磁浮列车无线辅助供电系统功率大、效率高等应用需求特点,开展磁耦合机构和谐振补偿电路优化设计。建立了单发多收磁耦合机构有限元模型,对比分析了3种无线供电系统谐振补偿拓扑(S-S,LCC-S,LCC-LCC)的工作特性,并基于Pareto最优解概念提出全局多目标优化设计策略。通过搭建8.5 kW无线辅助供电系统样机进行了验证,试验结果表明,所提优化方案能满足磁浮列车无线供电的设计需求,能量传输效率达到91.9%。During the operation of maglev trains approaching stations,the electric energy generated by the linear generators propels the trains but is insufficient to meet the power demands of onboard equipment.Traditional contact power supply methods have shown deficiencies in various aspects,such as high installation and maintenance costs,as well as the safety risks associated with exposed live conductors.In contrast,wireless power transfer(WPT)technology eliminates the need for physical cable connections,allowing maglev trains to operate without mechanical contact and enhancing the safety,economic efficiency,and environmental adaptability of their auxiliary power supply system.This paper focuses on the optimized design for the magnetic coupling mechanism and resonant compensation circuit,addressing specific requirements of auxiliary WPT systems in maglev train applications including high power demands and efficiency requirements.A finite element model of a magnetic coupling mechanism with a single-transmitter multiple-receiver(STMR)configuration was established.The operational characteristics of three resonant compensation topologies(S/S,LCC/LCC,LCC/S)for WPT systems were compared and analyzed.A global multi-objective optimization design strategy was introduced based on the concept of Pareto optimal solutions.Furthermore,an 8.5 kW auxiliary WPT system prototype was built for verification.The experimental results demonstrated the proposed optimization scheme in meeting the design requirements of WPT systems for maglev trains,with an energy transfer efficiency of up to 91.9%.
