Analytical modeling of electrical potential repartition on piezoelectric transformer

Abstract

This article deals with an analytical modeling of the electrical potential repartition generated on the surface of receiving part of a piezoelectric transformer. The analytical model is exploited to verify the influence of structural and geometrical parameters on the amplitude and the repartition of electrical potential. Additionally, a 2D-model of surrounding electrical potential is undertaken by Finite Difference Method (FDM) from a weak coupling approximation.
