Active rectification of rotational electromagnetic energy harvesting using piezoelectric elements for AC/DC power conversion improvement

Résumé

In the present work, a cooperative hybrid electromagnetic-piezoelectric energy harvester for scavenging rotational energy is presented. More precisely, in order to improve the electromagnetic transducer's AC/DC power conversion efficiency, a half-wave voltage doubler by using MOSFETs is employed. The cooperative hybrid power harvesting is then achieved by powering the MOSFETs by means of the piezoelectric system. Simulation and experimental validations are presented, demonstrating the improvement of the energy conversion efficiency of the electromagnetic transducer.
