摘要 针对无线电能传输(WPT)系统线圈相对位置偏移引起传输效率降低、输出电流不稳定和发射线圈过电流问题,提出一种抗偏移恒流输出型WPT系统及其参数配置方法。该系统将LCC-LCC和串联-串联(S-S)补偿网络进行输入串联和输出串联,并采用QDQPs磁耦合结构。在此基础上,通过合理的参数配置,不仅实现了与负载无关的恒流输出,而且可以实现抗x方向、y方向、z方向以及xy方向线圈同时偏移的性能,还可以避免发射线圈过电流。该文分析所提系统的传输特性,从理论上证明了系统具有良好的抗偏移性能。最后,搭建了一个280W实验平台,验证了理论分析的正确性和可行性。

Abstract:For a wireless power transfer (WPT) system, the misalignment of coils can easily cause low transfer efficiency, unstable output current and over-current of transmitting coil. Therefore, this paper proposes a constant current output WPT system and its parameter design method with high anti-offset performance. In the proposed system, the LCC-LCC and S-S compensation network are connected in input series and output series, and the magnetic coupling structure of quadruple-D quadrature pads is adopted. Then, through reasonable parameter configuration, not only the load independent constant current output can be realized, but also anti-x direction, y-direction, z-direction and anti-xy direction can be realized. Moreover, the over-current of the transmitting coil is avoided. By analyzing the transfer property of the proposed system, it is proved theoretically that the system has good anti-offset performance. Finally, an experimental platform with 280W is built to verify the correctness and feasibility of the theoretical analysis.
