Abstract :
Piezoelectric transformer (PT) design requires finite element analysis (FEA) tools, because its performance depends strongly on its shape (2D/3D effect). The main drawback of these tools is that they do not provide the electrical model needed to design the power converter. Nevertheless, the existing electrical models only take into account the main direction of vibration (1D). In this paper, a procedure to improve 1D model parameters by taking into account FEA tool information is proposed.
