SPICE Model for Piezoelectric Bender Generators

摘要

This paper presents the equivalent circuit model of PBG (Piezoelectric Bender Generator) along with its SPICE implementation. The model, made of lumped circuit elements, is valid under both parallel and series wired PBG operation modes. The model is validated by comparing the simulation results, from the transient analysis of the model in SPICE, with those obtained by using MATLAB. An example using the proposed SPICE model is also presented.
