目前无人机一般续航时间短,无法实现长时间或远距离飞行。为此,提出了采用无线电能传输技术的无人机自主充电方案,可以有效增加无人机的飞行时间或距离。首先对无人机电池的充电特性进行了调研,研究并选取了最适合无人机自主充电的无线电能传输技术。接着利用电力电子变换器设计了相应的无人机无线电能传输系统,最后在MATLAB/SIMULINK中搭建了完整的仿真模型,验证了前面提出的无人机无线电能传输系统。仿真结果表明该系统具有良好的性能,能够很好满足无人机的充电需求。
The current UAV generally short life, unable to achieve long hours or long-distance flights. To this end, proposed a wireless power transfer technology UAV autonomous charging scheme, can effectively increase the UAV flight time or distance. Firstly, the charging characteristics of UAV battery were investigated, and the most suitable wireless power transmission technology for UAV self-charging was researched and selected. Then the corresponding UAV wireless power transmission system is designed by using power electronic converter. Finally, a complete simulation model is set up in MATLAB / SIMULINK to verify the UAV wireless power transmission system proposed above. Simulation results show that the system has good performance, can well meet the UAV charging needs.
