本文设计了一种新型的双通道动态无线充电系统耦合机构，以解决动态无线充电系统在分段式发射导轨切换处的功率跌落问题。通过LCC-LCC型补偿拓扑，设计了两路能量传输通道，利用LCC-LCC补偿拓扑的恒流特性，推导了系统输出以及损耗与两通道耦合参数之间的关系，实现了较为稳定的功率传输，提升了系统的抗偏移特性以及抗跌落能力。最后对所提方法进行了仿真和实验，验证了双通道动态无线电能传输方案的可行性。

In order to reduce the power drop of dynamic wireless charging system at the transmission rail switch, a new coupling mechanism of dual channel dynamic wireless charging system is designed. The LCC-LCC compensation topology is selected to design two energy transmission channels. By using the constant current characteristics of LCC-LCC compensation topology, the relationship between system output and loss and two channel coupling parameters is deduced, which realizes relatively stable power transmission and improves the anti offset characteristics and anti drop ability of the system. Finally, the proposed method is simulated and tested to verify the feasibility of the two-channel dynamic wireless power transmission scheme.
