Finite Element Simulation of Thickness Vibration Mode Multilayer Piezoelectric Transformer

In this study, vibration mode multilayer piezoelectric transformer was designed and thickness simulated using ANSYS of finite element method simulator for investigating its optimum conditions ist. As a results, resonant frequency was decreased with the increase of output layer thickness, Output voltage, maximum displacement and maximum stress at 0.34mm thickness transformer were 228.1 V, $0.42{\mu}m,\;8.78[N/m^2]$ respectively.
