Electrostatic vibration energy harvester with increased charging current

Abstract

The analysis of the operation of the electrostatic vibration energy harvester to charge self-contained power supply is carried out. An analytical expression to estimate the average charging current taking into account diode's reverse current is obtained. The ways to increase the charging current were found. The harvester with increased charging current containing no switches and inductive elements is suggested. © Published under licence by IOP Publishing Ltd.
