Development of a 3-D Finite-element Solver for Piezoelectric Transformer Analysis

Chen Y-M, Lee C-K, Yang Y-J, National Taiwan University, TW

Piezoelectric transformers step up or step down input voltages by electrical/mechanical/electrical conversion. Piezoelectric transformers have been proved to be promising alternatives for magnetic transformers. Furthermore, since the fabrication technology of thin-film piezoelectric materials becomes mature, [...]
