Abstract
This paper presents an equivalent circuit model of an impact-based piezoelectric energy harvester. The harvester alternately generates two different shapes of damped- oscillating signals due to the asymmetric structure of the device. Those signals have strong high frequency components through mechanical impact from low frequency vibration. Equivalent circuit model with dual voltage source is proposed to precisely describe the behaviour of the harvester. The simulation results of the harvester with typical conversion circuits were compared with measurement data to verify the correctness of proposed model.
