摘要
Abstract
An enhanced series synchronous switching inductor interface circuit(ES-SSHI)was proposed to improve the energy harvesting efficiency of vortex induced vibration piezoelectric energy harvesters and to achieve better adaption to the load variation of the interface circuits.The calculation formula was obtained through theoretical analysis for the energy harvesting efficiency of the interface circuit.ES-SSHI was then simulated and analyzed using Multisim circuit simulation software.And the output power curve of the interface circuit was obtained during load variation.Finally,a wind tunnel testing device and interface circuit were actually built for the vortex induced vibration piezoelectric energy harvester.The actual collected power was tested and analyzed for the energy harvester interface circuit.The results show that the theoretical average power is 220 μW with peak value of 265.1 μW for the ES-SSHI circuit,and the measured maximum output power is 98.2μW.The output power is significantly higher than that of the popular current circuits,and the load adaptability is better.关键词
