Abstract
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(Zr <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">52</inf> Ti <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">48</inf> )O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> polycrystalline material.

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.
