"In this paper, a switching damping system that can widen the operational bandwidth of an electromagnetic vibration energy harvester is presented. In the system, the damping is switched periodically within each oscillation cycle in response to the real-time position and velocity of the devices resonator. A comprehensive timing model of switching damping device is derived analytically and its resonant frequency is computed by using the MATLAB solver. The simulated results demonstrate that natural frequency of the system can be shifted up or down for a reasonably range of natural frequency by switching the electrical induced damping. The results also indicate that for a higher damping system, the devices natural frequency can be shifted up to the range of +20.2 and -58.6 away from the initial natural frequency. However, the drawback is that the switching damping system will affects the peak output, which is highly dependent on the value of the damping. © 2015 IEEE."^^ . "2016" . . .
