Abstract
The linear synchronous generator for harnessing vibration energy was investigated in this study. The linear synchronous generator comprises the permanent magnet in the stator and the coil in the vibration portions. The vibration energy is converted to electric energy using a linear synchronous generator. Electric Double-Layer Capacitor stores the generated. Additionally, it is used as a damping device. The charging and damping characteristics of the linear synchronous generator are investigated by varying the initial energy given to the vibration portion and the frequency of the vibration. The charging characteristics are increased as the initial energy given to the vibration portion increases. The charging characteristics are decreased, and the damping characteristics are improved as the vibration frequency increases. The charging circuit that divides the voltage is created to improve the charging characteristics. The charging energy is influenced by power consumption and mechanical loss. Concerning these factors, an optimal reference voltage is given. The charging energy is maximized when the reference voltage is 0.4 V. When the reference voltage is 0.4 V, the charging energy is increased by 1.3%. The vibration stop time is reduced by 9.4%, and the damping factor is shown to increase.
