In this paper an analysis and modeling methodology of piezoelectric transformers is presented. Three-dimensional simulation by Finite Element Method is utilized to obtain the Mason lumped parameter model. The PT has been prototyped and the experimental measurements are compared with the simulations. The results show that the simulation in three-dimensional environment by Finite Element Method reveals...
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...
A novel design method - narrow control bandwidth for the PT power converter has been proposed according to the electrical characteristics and the operation features of PT. The method has been proved through the input matching network of PT. The main contributions are as follows: 1) The functions of the input matching network has been analyzed; the design method has been put forward and the parameters...
