由于体积大、污染环境、需要定期更换,传统电池供能方式已不能适应当前外场工作的需求.涡激振动的微型风能采集装置将风能转换成电能,能够对无线传感节点等微型电子设备直接供电.基于经典Buck-Boost电路,提出了一种适用于涡激振动微型风能采集的能量接口电路.通过理论与仿真分析,所设计的能量接口电路存在最优占空比,及其对应的最大功率点.基于LabVIEW平台设计了控制程序,实验结果表明,所设计的电路与程序能够对占空比进行自动寻优,保持微型风能采集装置以最大功率输出. |

Due to the large size,environmental pollution and requirement of periodically replacement, the classic batteries are no longer suitable for field work nowadays. Micro-wind energy harvesting by vortex-induced vibration can harvest the wind energy,and power the micro electric equipment such as wireless sensor nodes. Derived from the Buck- Boost circuit,a new energy interface circuit is designed for the micro-wind energy harvesting device. After theoretical analysis and simulation, there is an optimal duty cycle in the proposed circuit,which corresponds to the maximum output power. A control algorithm is developed with LabVIEW platform. Experimental results show that the proposed circuit and control algorithm can achieve the optimal duty circle,and keep the micro-wind energy harvesting outputs at its maximum power. |
