Adaptive piezoelectric energy harvesting circuit for wireless remote power supply
TL;DR: In this article, an analytical expression for the optimal power flow from a rectified piezoelectric device is derived, and an energy harvesting circuit consisting of an AC-DC rectifier with an output capacitor, an electrochemical battery, and a switch-mode DC-DC converter that controls the energy flow into the battery.
Adaptive piezoelectric energy harvesting circuit for wireless, remote power supply
TL;DR: Experimental results reveal that use of the adaptive DC-DC converter increases power transfer by over 400% as compared to when the DC- DC converter is not used.
Journal ArticleDOI
Optimized piezoelectric energy harvesting circuit using step-down converter in discontinuous conduction mode
TL;DR: In this paper, an optimized method of harvesting vibrational energy with a piezoelectric element using a step-down DC-DC converter is presented, in which the converter regulates the power flow from the PPE element to the desired electronic load.
