Analytical Study on the Ideal Response of Normal-Mode Shock-Depoled PZT Ferroelectric Ceramics with Resistive, Capacitive, and Inductive Loads.

Electrical equations have been derived for the ideal response of normal-mode shock-depoled PZT ferroelectric ceramics with resistive, capacitive, and inductive loads. It was assumed in the analysis that charge was released from the PZT material completely and instantaneously at the shock front. Both rectangular and hollow-cylinder shapes were considered for the PZT unit. Expressions for the charge, voltage, current, and energy in the circuit were obtained for times during and after the traversal of the unit by the shock front. These results and the electrical properties of shock-depoled PZT 56/44 ceramics were used to estimate the geometrical size of PZT units in single-shot pulsed power supplies for energy converters with resistive and capacitive input characteristics.
