Note: Autonomous pulsed power generator based on transverse shock wave depolarization of ferroelectric ceramics

Abstract

Autonomous pulsed generators utilizing transverse shock wave depolarization (shock front propagates across the polarization vector P0) of Pb(Zr0.52Ti0.48)O3 poled piezoelectric ceramics were designed, constructed, and experimentally tested. It was demonstrated that generators having total volume of 50 cm3 were capable of producing the output voltage pulses with amplitude up to 43 kV with pulse duration 4 s. A comparison of high-voltage operation of transverse and longitudinal shock wave ferroelectric generators is given. © 2010 American Institute of Physics.
