A Three-Phase Microgenerator Based Solution for Power Harvesting Applications

Abstract

With the fast growth of wireless communications between nodes/sensor units, devices installed in remote places require continuously energy supply for their functionality or communication requirements. For these applications energy harvesting takes place as a good solution to increase the availability of energy, in opposition to the conventional systems of energy supply. Regenerative energy sources like thermoelectric, magnetic, piezoelectric, and/or renewable sources such as photovoltaic and wind, among others, allowed the development of different powering solutions for sensor units. The purpose of this work is to characterize a three-phase micro generator that is used to convert the energy extracted from wind or water flow, among others mechanical energy sources, to electrical energy. The study is carried out taking into account the velocity of axis versus power provided to a load.
