In this paper, new piezoelectric transformers for AC–DC converters and DC–DC converters are presented. These piezoelectric transformers operate in a higher vibration mode. They were designed to be multilayered in the thickness direction to achieve high-power operation. First, we performed the simulation for designing a transformer using finite element method (FEM) analysis, and calculated its size using $V_{\text{in}}=100$ V, $V_{\text{out}}=10$ V, $P_{\text{out}}=20$ W, and an efficiency $\eta$ of more than 90%. Second, we simulated some electrode patterns of a multilayered piezoelectric transformer. We investigated experimentally the transformers manufactured using the simulation results, and the highest efficiency of 93.7% was obtained.
