摘要/Abstract

摘要： 针对能量回馈型超声波电动机振动能量采集系统，建立了其等效电路模型，给出了系统能量流图，分析了不同接口拓扑电路下的系统能量组成，建立了系统电荷-电压轨迹图，定量分析系统采集能量、损耗能量以及提取能量，数值分析了拓扑电路整流电压系数、二极管导通压降、电压翻转系数及机电耦合系数等对采集能量、损耗能量及提取能量的影响，试验验证了数值分析结果的正确性。研究结果表明机电耦合系数越大、开关电路电压翻转系数和二极管导通压降越小，越有利于提高能量采集系统的输出性能。

Abstract: Focusing on the vibration energy harvesting system (VEHS) of the energy harvesting type ultrasonic motor (EH-USM), the equivalent circuit model and the energy flow chart of the VEHS are established, the energy constitute and the charge-voltage locus under different interface topology circuits are also derived. The harvesting energy, dissipating energy and extracting energy of the VEHS under different interface topology circuits are quantitatively studied. Simulations are performed to exhibit the effects of the rectified voltage factor, the conduct voltage drop factor of the diode, the voltage conversion factor and the electromechanical coefficient on the harvesting energy, the dissipating energy and the extracting energy. The validity of the numerical results is testified by the experiments. Research results have shown that a larger electromechanical coefficient and a smaller voltage conversion factor as well as the conduct voltage drop factor of the diode are benefit to improve the harvesting output performances.

Key words: energy flow chart, interface circuit, ultrasonic motor, vibration energy harvesting
