Miniature 100-kV explosively driven prime power sources based on transverse shock-wave depolarization of Pb(Zr0.95Ti0.05)O3 ferroelectric ceramics

摘要

Our previous efforts [1-7] were focused on designing, constructing and investigating miniature shock wave ferroelectric generators (FEGs) based on Pb(Zr0.52Ti0.48)O3 (PZT 52/48) poled ferroelectric ceramics (that is widely used in modern technology). In this paper, we extended our efforts to development of FEGs utilizing different type of ferroelectric materials, i.e. Pb(Zr0.95Ti0.05)O3 (PZT 95/5). The design of autonomous ultrahigh-voltage FEGs based on transverse explosive shock depolarization of poled PZT 95/5 ferroelectric ceramics was explored and studied. As a result of this work, miniature generators (diameter 38 mm) that are capable of producing output voltage pulses with amplitudes exceeding 120 kV and pulse widths of 3 μs were developed.
