Abstract

Our previous efforts were focused on designing, constructing, and investigating miniature shock-wave ferroelectric generators (FEGs) based on Pb(Zr_0.52 Ti_0.48)O₃ poled ferroelectric ceramics (that is widely used in modern technology). In this paper, we extended our efforts by exploring a different type of ferroelectric materials, i.e., Pb(Zr_0.95Ti_0.05)O₃ (PZT 95/5), for designing miniature autonomous shock-wave FEGs. The performance of autonomous ultrahigh-voltage FEGs based on transverse explosive shock depolarization of poled PZT 95/5 ferroelectric ceramics was studied. As a result of this paper, miniature generators (38 mm in diameter) that are capable of producing output voltage pulses with amplitudes exceeding 120 kV and pulsewidths of 3 μs were developed.
