Passive Damping with Piezoelectric Transducers

Abstract

This chapter analyzes the basic principle of passive damping with shunted piezoelectric transducers. Resistive shunting and inductive shunting are examined successively. The various ways of tuning the inductor (maximum stability and equal peak design) are carefully reviewed, and the robustness with respect to the shunt parameters is discussed. Next, the switch shunt is analyzed, leading to the technique known as synchronized switch damping on inductor (SSDI); the performances of the various shunting modes are compared. The chapter concludes with a short list of references and a set of problems.
