为实现利用压电材料进行环境能量转换的目的,设计了一种能利用风能驱动多片压电片振动发电的装置。该装置通过风能驱动叶轮旋转,利用叶轮的旋转扭力迫使压电片振动,将压电片振动产生的电能通过整流电路、储能电容及DC-DC转换后供负载使用。通过实验对压电片在不同条件下的发电性能进行了测试,实验结果表明,该装置可实现多片压电片对环境能量的收集转换,为此类装置的设计提供了参考,同时也为压电环境能量采集技术提供了新思路。

In order to realize the purpose of environmental energy conversion based on piezoelectric materials, a generating device was designed which could use wind energy to drive multiple piezoelectric patches vibration. The impeller revolving of the device was driven by wind energy, then the torque force of the revolve impeller was utilized to vibrate piezoelectric patches, finally the energy generated from piezoelectric patches were supplied for the load after rectifying, store and DC-DC convert. The power generation performance of piezoelectric patc...
