Abstract
Triboelectric power generators are extensively studied because of their high efficiency, low manufacturing cost, and high output voltage. However, the internal impedance of the generator is extremely high, the output power conversion efficiency is lowered, and its practical use has been limited. Therefore, in order to increase the output power by matching the high output impedance of the triboelectric power n generator, we studied a passive power management circuit that turns on and off the unidirectional switch by deformation of the friction generator, drives the coupling inductor, and charges the capacitor after bridge rectification. As a result, about 9 times the output power conversion efficiency was confirmed as compared with that charged directly after the bridge rectification.
