EXPERIMENTAL STUDY OF THE NONLINEAR PHOTOCONDUCTIVE SWITCH

The essential principle of the nonlinear photoconductive semiconductor switch (PCSS) is reported,with emphases on the experimental study of the output characteristics.The linear and nonlinear mode of the switch is compared,and the nonlinear output waveform of the switch is given.The factors affecting the delay time and the rise time are researched,and the relation between the applied voltage threshold and trigger optical energy threshold is measured.lt is indicated that the feasibility of making use of the PCSS to develop a new solid,high voltage and high power ultra short electric pulse generator.
