Analysis and modeling of output power of cantilever piezoelectric vibration energy harvester
摘要
Abstract
This paper investigates the approximate formula of the output voltage of cantilever piezoelectric vibration energy harvester and derives the equivalent output model of the constant current source under the condition of low resistance load through theoretical analysis from the equivalent circuit of the common structure combined with the structural parameters and the electrical parameters of energy harvesters,and thus concludes the output voltage formula of the multi-device parallel topology.Based on this theoretical analysis,this paper also simulates the cantilever piezoelectric vibration energy harvester by Matlab,and the simulation results verify the correctness of these approximate formulas.关键词
