Abstract: Abstract A ring-type step-down piezoelectric transformer based on 0.65Pb(Mg1/2Nb2/3)O3-0.35PbTiO3 ceramic was manufactured to study its main operational characteristics through experimental measurements and numerical simulations based on the corresponding electrical equivalent circuit. The measured resonance frequency… read more here.

DOI: 10.1109/tuffc.2020.2975647
Abstract: A 2-D semianalytical model using the Legendre polynomial approach was applied for modeling the piezoelectric transformer (PT). In the model, the mechanical displacements and the electric potential were expanded in a double series of orthonormal… read more here.
