Fast high voltage pulse generator with nonlinear transmission line for high repetitive operation

The pulse sharpening effect of nonlinear transmission lines (NLTL) with nonlinear power capacitors has been applied to fast high voltage pulse generation. NLTL can be utilized for high repetitive operation, since NLTL consist of only passive elements. The main problem of the scheme is difficulty of obtaining nonlinear power capacitors with high withstand voltage. In this study, the authors employed commercially available BaTiO/sub 3/ ceramic capacitors as the nonlinear power capacitors, and confirmed the high voltage operation of NLTL in the voltage range of up to 20 kV.
