The chaotic vibration energy harvester (CVEH) converts vibration of constructions to electric energy in wide frequency. It needs large computational cost for evaluation of the magnetic force between the moving magnets and magnetic material embedded in the stator coils of CVEH when using finite element method (FEM). This paper presents magnetic circuit modeling of CVEH to reduce computational burden. It is shown that the frequency responses of CVEH computed by the present method is in good agreement with those obtained by FEM. This result is validated through the experiment.
