摘　　要：基于磁耦合谐振式原理提出了一种适用于无人机机巢的无线电能传输系统。该系统采用串联-串联型谐振网络,通过输出功率预测算法和恒功率闭环控制实现恒功率无线供电。与现有的无线电能传输系统相比,无需额外的DC-DC变换器,仅用简单的控制方法就能实现恒功率输出,减少了系统的硬件成本和控制复杂性。最后,设计了一个20W,887kHz的实验平台,实验结果验证所提控制策略的有效性。This paper proposes a wireless power transfer system suitable for unmanned aerial vehicle nests based on the principle of magnetic coupling resonant.The system adopts the series-series resonant network and achieves constant power wireless power supply through output power prediction algorithm and output power closed-loop control.Compared with existing wireless power transfer system,there is no need for additional DC-DC converters,and constant power output can be achieved with simple control methods,which reduces the hardware cost and control complexity of the system.Finally,a 20W,887kHz experimental platform is designed.The experimental results verify the effectiveness of the proposed control strategy.
