The finite element method (FEM) is widely used in engineering, and the ANSYS program is accepted by researchers. In this paper, a step-down PZT-based (PZT-85) piezoelectric transformer is designed to explore the vibration and frequency characteristics of a piezoelectric transformer. The simulation results are in good agreement with the experimental measurements, despite small differences due to human and equipment errors. The results indicate that the combination of FEM simulations and experiment is effective for designing piezoelectric devices.
