Effect of Nonlinear Electromechanical Coupling in Magnetic Levitation Energy Harvester

This paper investigates the possibility of converting vibrations to electricity. A numerical and an experimental study a magnetic levitation harvester are proposed. The system can be highly efficient when electrical parameters correctly tuned. Mechanical interaction is described by electromechanical coupling. Fixed value, linear nonlinear coupling models presented compared. It has been shown that model more suitable for higher oscillations magnet. obtained results show resonance recovered energy controlled simple configuration magnet coil position. from top branch significantly higher, but this solution much harder obtain.
