基于频率变换的压电俘能器接口电路设计
Design of interface circuit of piezoelectric vibration energy harvester based on frequency transformation
摘要
Abstract
An interface circuit for double synchronized switch harvesting circuit (DSSH) which could descend matching inductance was designed,and its simulation model was established.The simulation results show that the maximum harvesting power is 1.9 mW.Compared to the general DSSH,it can reduce the size of the circuit by a factor of three.This circuit was applied to piezoelectric vibration energy harvestings with different shapes.It is found that the size and shape of the piezoelectric sheet all have impact on energy harvesting.A rectangular piezoelectric sheet at the vibration frequency of 40 Hz harvestes the most of the energy.关键词
