Abstract :
Through this study an attempt was made to find definite characteristics of BaTiO/sub 3/ ceramic capacitors, DE1207FI03Z2K manufactured by Murata Co. The rated DC capacitance and voltage of the device are 10 nF and 2 kV, respectively. The experimental relationships of electric induction, D = /spl epsiv/E V/m, and electric displacement field Q/S C/m/sup 2/ versus electric field E V/m for the capacitors were obtained for several current values. For each current the nonlinear permittivity (/spl epsiv/) changes of the capacitor in the linear and nonlinear area showed hysteresis characteristics analogous to B-H curves in magnetic materials. The experimental results showed that the use of such types of capacitor in designing repetitive nanosecond high voltage pulse generators has good prospects.
