At 350 kV/cm, Imax, CD, and PD reach 35.68 A, 504.98 A/cm 2, and 88.37 MW/cm 3, respectively. The higher the power density, the greater the potential of dielectric ceramic materials for pulsed applications. In general, BBLNT-VPP ceramic has good pulse performance at room temperature. Fig. 8.
The recoverable energy density of capacitors can be measured and calculated by the pulse discharge current curves in a high-speed switch circuit with load ( W d = R ∫ I ( t 2) d t / V, R and V are loaded resistance and the effective volume of the capacitors, respectively).
