Abstract
Vibration based energy harvesting with piezoelectric material is considered as an alternative power source to run the low power devices, specially for remote area where power is unavailable and also increasing high power demand in the world. This paper presents prototype implementation of non-controlled rectifier circuit utilizing piezo-bending generator (PBG) to estimate output power. This study also investigates the output power of PBG by choosing different capacitances, resistive loads and diodes. In this study, a non-controlled full-wave rectifier is designed and implemented for energy harvesting circuit (EHC). The energy harvesting rectifier circuit is simulated using Matlab software and implemented into prototype board to verify the results. Finally, the study concludes that the output power of the rectifier circuit is high with low resistive loads and Schottky diodes, and the output voltage becomes smooth with suitable value of capacitance.
