非接触感应式功率传输系统线圈的优化设计

Optimized Design of Coils for Non-contact & Inductively Coupled Power Transfer

目前,常见的轨道式感应耦合电能传输(Inductively Coupled Power Transfer,ICPT)系统采用原边具有LCL恒流特性、副边LC并联电容补偿拓扑的结构。针对常见的ICPT系统结构进行建模,通过模型导出线圈设计时的重要参数;采用Maxwell 3D有限元软件对线圈进行仿真并通过实验验证其优化设计方案。实验表明,线圈在1 000 W设计方案下能稳定运行,可较好应用于轨道式ICPT系统。

At present,the common rail type inductively coupled power transfer system（ICPT）adopts the struc-ture of LCL constant flow characteristic of the original side and the compensation topology of the side LC shunt capacitor. The common ICPT system structure is modeled, and the important parameters of coil design are derived through the model. The Maxwell 3D finite element software is used to simulate the co il,and the optimal design scheme is verified by experiments. The experimental results show that the coil can be stably operated under the 1 000 W design scheme and can be applied to the orbiting ICPT system.
