本文提出了一种能够从高速涡流中获取能量的气流能量采集器。气流能量采集器使用改进的螺旋萨沃纽斯涡轮机和电磁发电机来实现。具有最大功率点发现能力的功率管理模块用于管理收集的能量并将来自发电机的低电压幅度转换为无线传感器的可用水平。气流能量采集器的特征在于利用空气在风洞中撞击板而产生的涡流。以风速为17 m/s的飞机环境为例，测得气流能量采集器的输出功率为126 mW。功率管理模块的整体效率为45.76至61.2%，风速为10至18 m/s时的最大功率点跟踪效率为94.21至99.72%，最大功率点跟踪电路的静态电流为790 nA。
An airflow energy harvester capable of harvesting energy from vortices at high speed is presented in this paper. The airflow energy harvester is implemented using a modified helical Savonius turbine and an electromagnetic generator. A power management module with maximum power point finding capability is used to manage the harvested energy and convert the low voltage magnitude from the generator to a usable level for wireless sensors. The airflow energy harvester is characterized using vortex generated by air hitting a plate in a wind tunnel. By using an aircraft environment with wind speed of 17 m/s as case study, the output power of the airflow energy harvester is measured to be 126 mW. The overall efficiency of the power management module is 45.76 to 61.2%, with maximum power point tracking efficiency of 94.21 to 99.72% for wind speed of 10 to 18 m/s, and has a quiescent current of 790 nA for the maximum power point tracking circuit.
