Numerical calculation of ferroelectric power supply initiating metal bridge foil

To investigate the effect of ferroelectric power supply initiating metal bridge foil, the electrical responses of the shock-loaded PZT95/5 ferroelectric with copper bridge foil load were numerically calculated. The non-linear resistance model was used for the metal bridge foil. The voltage, current, and resistance of metal bridge foil under different number of ferroelectric blocks arranged in parallel were calculated. By the results of calculated voltages and resistances of copper bridge foil, the number of parallel ferroelectric blocks to make copper bridge exploding was obtained. The calculation and results provide a theoretical basis to design the ferroelectric power supply initiating metal bridge foil.
