Abstract

The present invention relates to a generator concept by means of which, in particular, the effects of so-called nuclear electromagnetic pulses on electrical or electronic devices can be simulated by applying the so-called current injection technique. In the context of the generator concept according to the invention, in particular, a pneumatically controllable very fast spark gap is disclosed. Furthermore, a generator circuit having two spark gaps (40, 41) is disclosed which is capable of generating a voltage pulse having an amplitude which is four times as large as the voltage of its voltage supply. With the exception of the spark gaps, the components 42-49) of the generator circuit only need to be designed for the above voltage of the voltage supply with respect to their continuous loading. The generator circuit according to the invention, in particular in conjunction with the spark gap according to the invention, allows a very fast efficient pulse generator to be constructed.
