Abstract: This paper presents a coupled analysis of electromagnetic vibration energy harvester (VEH) on the basis of the nonconforming voxel FEM. In this analysis method, the motion, Maxewell, and circuit equations are alternatively solved using the staggered method. The FE models can be generated in this method with low computational costs. By using the coupled analysis method, the characteristics of a VEH model, which contains the magnetic material in the coil, is analyzed changing the geometric parameters. It is shown from the analysis results that the VEH model has chaotic and linear oscillations. It is also shown that output power can be generated for a wide frequency range in the chaotic mode, and in the linear mode, large output power is obtained at the resonance.
