title: Modeling and identification of Rosen-type transformer in nonlinear behavior.
abstract: This paper is about the modeling of piezoelectric transformer in nonlinear behavior conditions. In the frame of applications with high output loads, nonlinear behavior be comes non-negligible. First, the origins of nonlinearities and theoretical approaches are preliminarily discussed. Then, the model is developed for a typical Rosen-type transformer and experimental investigations are presented. The results are used to confirm the validity of the analytical model and the methodology to express the terms added to the typical constitutive piezoelectric relations.
