Abstract

Bistable piezoelectric energy harvesters are prominent solutions in the field of vibration energy harvesting due to their broadband behavior. However, the impact of the electrical interface and especially the load impedance needs to be addressed. In this study, the impact of the electrical load resistance on the dynamic of the bistable piezoelectric energy harvester has been studied. Through a parametric study, the present paper shows that the load resistance impacts both the harvested power and the bandwidth of the harvester. The analytical expression of the mass displacement, critical angular frequency and harvested power have been obtained, based on a truncated harmonic balance method. A comparison between the analytical model and experimental measurement on a custom bistable energy harvester is then presented. The experimental results are in good agreement with the analytical model, which proves the validity of the proposed model and analysis. The results presented in this study should be considered in the development of maximum power point tracking algorithms and orbit jump strategies.
电阻性负载对双稳态能量采集器功率和带宽的影响
双稳态压电能量收集器由于其宽带特性成为振动能量收集领域的突出解决方案。但是,需要解决电接口的影响,特别是负载阻抗的影响。本文研究了负载电阻对双稳态压电能量采集器动态特性的影响。通过参数化研究,表明负载电阻对采集功率和采集带宽都有影响。基于截断谐波平衡法,得到了质量位移、临界角频率和收获功率的解析表达式。在此基础上,对双稳态能量采集器的分析模型和实验结果进行了比较。实验结果与分析模型吻合较好,证明了模型和分析的有效性。本研究结果应在最大功率点跟踪算法和轨道跳跃策略的开发中加以考虑。
