Paper Abstract

Optically triggered semiconductor switches are a useful tool to generate steep high power pulses. The properties of these switches allow a fast switch closure with low jitter. Thus a parallel operation of a number of switches in various geometric arrangements is possible. This paper reports on investigations to examine how the two well-known operation modes of such switches, the linear and the non-linear photoconductive mode, can be combined in order to optimize the trigger effort in relation to the switch properties. Furthermore, it is investigated, whether such switches can be applied in a low-impedance pulse generator to generate 30 - 50 kV rectangular voltage pulses, duration 20 ns, at an impedance of 0.2 (Omega) . In addition some experiments are outlined where such switches are used to produce steep high voltage pulses in order to improve the simulation of electromagnetic stresses.
