Architecture and Optimization of a Low-Frequency Maglev Energy Harvester

Low-frequency harvesters are attractive due to their availability in the ambient environment. The paper presents the design, analysis and optimization of the magnetic levitation harvester. A new nonlinear model of the electromechanical coupling, depending on the magnet position versus coil is proposed. Additionally, the influence of magnetic suspension (stiffness), load resistance and magnet-coil configuration on the foldover effect is shown.
