与单相无线电能传输系统相比，三相无线电能传输系统具有传输功率大、位置偏移容限高、输出纹波小等优点，其已广泛用于高功率应用。对于三相轨道式动态无线电能传输系统，相间的交叉耦合互感，会导致三相不平衡，建模和分析困难。为此，提出并优化了一种新型的三相轨道式磁耦合结构。首先，提出了一种用于三相轨道式动态无线电能传输系统的磁耦合结构。其次，利用物理原理和数学工具计算系统的一次、二次等效参数，建立了系统的全解耦等效数学模型。第三，在此模型的基础上，分析了系统的功率和效率等输出特性。最后，搭建了1 kW三相轨道式动态无线电能传输系统实验平台，对理论分析进行了验证。实验结果表明，本文提出的磁耦合结构能很好地解决相间交叉耦合互感引起的系统不平衡问题，提高系统的功率和效率。
Compared with the single-phase wireless power transfer systems, the three-phase wireless power transfer systems have the advantages of large transfer power, high position offset tolerance, and small output ripple, etc., which have been widely used for high-power application. For a three-phase rail-type dynamic wireless power transfer system, the interphase cross-coupling mutual inductance, will lead to three-phase unbalance, difficult modeling and analysis. So, a new type of three-phase rail-type magnetic coupling structure is proposed and optimized. Firstly, a magnetic coupling structure for a three-phase rail-type dynamic wireless power transfer system is proposed. Secondly, the physical principle and mathematical tools are used to calculate the primary and secondary equivalent parameters of the system, and a fully decoupled equivalent mathematical model of the system is established. Thirdly, based on the model, the output characteristics of the system such as power and efficiency are analyzed. Finally, an experimental platform for a 1 kW three-phase rail-type dynamic wireless power transfer system is built to verify the theoretical analysis. The experimental results show that the magnetic coupling structure proposed in this paper can well solve the problem of system imbalance caused by interphase cross-coupling mutual inductance, and improve the power and efficiency of the system.
