基于燃料电池的无人飞机混合动力系统设计

Fuel cell battery hybrid system for UAV

在分析了燃料电池的特性及无人机要求的基础上,设计了一套应用于燃料电池无人飞机的混合动力系统,并利用二极管和DC/DC末端电压的调整来实现锂电池的投入和切出。讨论了混合系统的方案,给出了系统的软硬件设计。最后通过实验测试,验证了该系统达到设计要求,既能保证燃料电池的安全长寿,又可满足无人机的功率需求。

A fuel cell battery hybrid system for UAV was designed based on the characteristic of fuel cell and UAV; diode and DC/DC was used to control the out put of battery. The scheme of the hybrid system was discussed first and then the design ol both hardware and software was presented in this paper. Finally, through the experimental test, the hybrid system was proved successfully, which could not only make the fuel cell working safely but also fulfill the demand of the UAV.
