Study and Modeling of a Traveling Wave Piezoelectric Transformer

Abstract : This paper reports the study and the modelling of a new topology of traveling wave piezoelectric transformer (TWPT). Unlike conventional piezoelectric transformers, the proposed transformer uses progressive waves to carry out the electromechanical conversion. Moreover, associated with an appropriate converter, it enables any kind of AC-DC or AC-AC power conversion. An analytical modelling of the system is carried allowing defining numerically the voltages, currents, displacements and stresses in the piezoelectric transformer over time as a function of the geometrical and physical parameters of the materials.
