Abstract :
An analysis method of piezoelectric transformers (PT) for switching power supplies is presented based on three-dimensional (3D) simulation. In order to illustrate the 3D nature of the factual PT, a 3D model is developed. A simulation method is presented to link the converse piezoelectric effect and direct piezoelectric effect of PT. The simulation is implemented by using a finite element analysis (FEA) software, ANSYS. The properties of the PT are calculated and analyzed. The results show that the simulation study in 3D environment reveals the physical properties of PT satisfactorily. Moreover the simulation tool is a convenient and easily accessible simulation software package
