Abstract:

Gas gun impact techniques have been used to pulse charge nanofarad capacitors from the shock depoling of PZT 5644 and PZT 955 ferroelectric ceramics. The PZT materials were depoled in the normal mode. Pulse powers of hundreds of kilowatts were produced in a few microseconds. The PZT 5644 material was impacted in the stress range from 4.4 to 11.8 GPa. A maximum load voltage of 55 kV was produced at 7.9 GPa. Shock-induced electrical breakdown in the PZT material occurred at 11.8 GPa. The PZT 955 material was impacted at 1. 4 and 2.9 GPa stress levels. A maximum load voltage of 81 kV was produced at the higher stress.
