Modeling of Low Power Electrostatic Wind Energy Harvester for Macro-Scale Applications
Keywords:
Electrostatic harvester, energy harvesting, variable capacitor, wind energy.Abstract
The aim of this paper is to investigate the performance of a new macro scale electrostatic harvester model linked to a micro wind turbine. The harvester consists of a multi-poles rotary capacitor and a converter circuit. First, the model of the harvester is implemented in Matlab/Simulink. Next, the validated model device parameters such as the passive elements and the battery capacitance are varied to extract the optimal harvested power. Results indicate that maximum harvested power is 4.76 mW at a wind speed of 10 m/s with harvested energy of 219 µJ per cycle.
