压电能量收集系统作为一种自发电系统,可以将施加在系统上的压力转换为可供负载使用的电能。以100μm厚的PVDF薄膜作为压电能量收集系统的能量来源,以电学与力学为基础,设计了一种基于PVDF薄膜的压电能量收集系统;用ANSYS软件建立模型仿真,用origin软件处理PVDF薄膜输出信号参数,确定了箱式结构下的压电薄膜双并联结构;设计了采用三倍压电路的基于LTC3588芯片的能量收集电路,使得能量采集效率提升了3倍。
As a self-generating system,piezoelectric energy collection system can convert the pressure applied to the system into electrical energy for load.This paper used 25 μm thick PVDF film as the energy source of piezoelectric energy collection system.Based on electricity and mechanics,a piezoelectric energy collection system based on PVDF film was designed.Then,the model simulation was established with ANSYS software,and the output signal parameters of PVDF film were processed with Origin software to determine the optimal parallel number structure of piezoelectric film under box structure.In addition,an energy collection circuit based on ltc3588 chip using triple voltage circuit was designed,which improved the energy collection efficiency by three times.
