COMPARISON OF INTERFACE CIRCUITS FOR PIEZOELECTRIC WIND ENERGY HARVESTING FROM GALLOPING OSCILLATION
Piezoelectric wind energy harvesting system has risen as a competitive candidate to scavenging energy from ambient environment for power supply of remote sensors and actuators.It is mainly composed of two parts as piezoelectric structure and interface circuit.In this paper, a right-angle piezoelectric cantilever beam is used to harvest wind energy from galloping oscillation.Vibration characteristics of the piezoelectric cantilever beam are studied numerically and experimentally.Three classical interface circuits, namely standard, P-SSH, and S-SSHI, are adopted to complete AC-DC conversion for the practical application.Performances of the wind energy harvesting system with different interface circuits are analyzed,tested, and compared.
