Operation of the Longitudinal Shock Wave Ferroelectric Generator Charging a Capacitor Bank: Experiments and Digital Model

Systematic experimental studies and digital modeling of a two-stage, compact, completely explosive pulsed power system based on an explosive-driven ferroelectric generator (FEG) and a capacitor bank were performed. The FEG operation is based on the physical effect of longitudinal (shock wave propagates along the polarization vector P) shock wave depolarization of poled lead zirconate titanate Pb(Zr52Ti48)O₃ polycrystalline material. Experimental data are presented for FEGs containing Pb(Zr 52Ti48)O₃ energy-carrying elements of different dimensions, and capacitor banks of a wide range of capacitances. As a result, the developed digital model correctly predicts pulsed power generation in the system over a wide range of output power, up to 0.3 MW. ©2007 IEEE
