On hybridization of electromagnetic vibration converters

Bradai, Sonia / Naifar, Slim / Elleuch, Riadh / Kanoun, Olfa


Nowadays, harvesting energy from vibration is more and more challenging in terms of the maximum energy density that can be reached through the converter. The maximum energy density depends strongly on the applied excitation properties (frequency, acceleration), the principles used to convert themechanical energy to electrical energy and the system design itself. In this chapter, we focus on possible vibration converters dedicated to low vibration frequencies. Electromagnetic and magnetoelectric energy harvesting techniques deliver energy with relatively high efficiencies and are, therefore, the most promising principles, compared to piezoelectric, electrostatic and magnetostrictive principles. Furthermore, opting for hybrid solutions enables us to improve the limited energy outcome of a single converter. In this chapter, hybrid vibration converters based on the combination with the electromagnetic principle in macro scale are reviewed and compared.
