Abstract: The small-sized magnetoelectric generator has many advantages such as high power density, small axial size,long-term storage, and good prospects for fuze power supply. The output performance of the magnetoelectric generator is influenced by the coil parameters and the magnetic circuit structure, and it is difficult to get the analytical model. In order to analyze the output performance of magnetoelectric generator theoretically, the output voltage of the generator by method of combining analytical derivation and simulation analysis can be otained. The magnetoelectric generator were designed and machined according to the calculation results. The experimental results of the output performance of the magnetoelectric generator show that the error between the theoretical analysis and experimental results is only 0.2%, which proves the rationality of the calculation method proposed in the present paper.
