Design and FEM Analysis of Multilayer Piezoelectric Transformer for AC-adapter

AC-adapter를 위한 적층형 압전트랜스포머의 설계 및 유한요소해석

This paper present a new sort of multilayer piezoelectric ceramic transformer for AC-adapt. This piezoelectric transformer operates n the second thickness extensional vibration mode. The output voltage of the multilayer piezoelectric transformer was simulated using ANSYS. As results, the maximum stress appeared at the two points where one is the middle of input and the other is middle of output side in Second thickness extensional vibration mode. And output voltage was inversely decreased by increasing number of output layers.
