Current Output from Sandwich-structured Ferroelectric Power Supply

PZT 95/5 ferroelectric ceramics with niobium doped has been assembled for the pulsed power supply, and the electrical current output has been investigated under the action of shock wave in a ``normal mode.'' The PZT 95/5 ferroelectric ceramics are shocked simultaneously by two shock waves from the two parallel surfaces, so a sandwich-structured ferroelectric power supply is formed. Double current output has be obtained and a high-power electrical pulse over 5 kA is achieved. Theoretical calculation was conducted and a good agreement with the experiment is presented.
