Paper Abstract

Though there exist numerous researches concentrating on theoretical modelling of an electret-based vibration energy harvester (eVEH) connected with a pure load resistor, holistic modelling of eVEH with DC interface circuits is rarely studied. In this paper, a theoretical model of the eVEH connected to a DC interface circuit with a full bridge rectifier is proposed and validated by simulation and experiment. The power loss of eVEHs due to the reverse current leakage of diodes in the rectifier is investigated. The results show that the diodes with large reverse current are not recommended to construct the rectifier for eVEHs, due to the large impendence feature of the eVEH.
