摘要
提出一种适用于轨道交通无接触供电(WPT)系统的新型松耦合变压器结构,沿轨道敷设的一次侧发射线圈是一种三相Z型结构,首先分析了一次侧和二次侧线圈的电磁耦合作用,得到一次侧和二次侧线圈的等效互感,计算了互感模型下二次侧线圈映射到一次侧的等效阻抗。在Maxwell中搭建了三相松耦合变压器模型,得到了一次侧线圈的电磁参数,利用PSIM分析了系统功率输出特性。结果表明提出的Z型三相松耦合变压器结构具有电磁耦合性能好、空间容错性强和系统阻抗对称的特点。
The paper proposes a Z-type three-phase loosely coupled transformer, and the magnetic coupling of the primary and secondary coils are analyzed. The equivalent mutual inductance is obtained, and the equivalent impedance that mapping to the primary side from the secondary side is calculated. The model of wireless transformer is built in Maxwell to get the simulated parameters. The output characteristic is analyzed in PSIM. The results show the feasibility of three-phase WPT system and correctness of the analysis.
