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.
本文讨论了在高输出负载应用中，处于非线性行为条件下的压电变压器建模问题。在这种情况下，非线性行为变得不可忽略。首先，初步讨论了非线性的起源和理论方法。然后，针对典型的罗森型变压器开发了模型，并进行了实验研究。研究结果用于验证分析模型的有效性以及表达典型压电本构关系中添加项的方法。
