Abstract:Against the backdrop of a world energy crisis, triboelectric nanogenerator (TENG) is considered to be a practical solution that could harvest and use different types of mechanical energy. This study fabricates a variable rotor TENG combined with double limiting Zener aspectant diodes (ZAD) for the harvesting of impact energy and stable voltage output. And double limits are used at both ends of the load. The system has two independent rotor generating units. In a small impact, one generating unit is easy to start up; in a strong impact, two generating units operate to output more energy. This article presents a power management circuit design, which mainly comprises a rectifying part and voltage stabilizing part. In the operation of one generating unit, the voltage is stabilized at 3.35 V when using a single Zener diode, and at 3.95 V when using the ZAD circuit. In the simultaneous operation of two generating units, the voltage is stabilized at 4.45 V, ripple coefficient of 1.8%, and ripple voltage is 80 mV at millivolt-level when using the ZAD circuit. This article presents the prospects of stabilizing the output voltage of the TENG under random excitation in the harvesting of impact energy.
