太阳能无人机能源管理器研究与设计

Research and design of power management system of solar unmanned aerial vehicle

对太阳能无人机能源管理器的设计进行了详细的阐述,对能源系统各个工作状态进行了实验验证。该方案设计选用最大功率点跟踪(MPPT)半调节母线拓扑技术,成功实现了对电源系统中太阳阵、锂离子电池以及锂硫电池管理功能,该方案设计电路适应性强,各方面性能均比较理想,对临近空间电源系统具有很好的适用性。

The power management system（PMS） of the solar unmanned aerial vehicle（UAV） was introduced. PMS had been tested with different working status. Maximum Power Point Tracking（MPPT） and the topology of semi-tuned bus were chosen by the design, and the design had the ability of managing the solar cell array,Lithium-ion battery and Lithium sulfur battery. The designed PMS with great adaptability and performance was useful in the application of UAV.
