Modular trigger generator for an over-voltage triggered Marx generator

Over-voltage triggering of a spark gap enables a synchronized operation of several Marx generators in repetitive operation without an increased wear of the electrodes. In order to generate the trigger pulses and apply them to one spark gap of a Marx generator a modular semiconductor-based pulse generator in combination with a transformer has been developed. As the power required for triggering depends on stage voltage and stray capacitances of the Marx generator, a modular set-up enables an easy adaptation of the trigger generator design to different types of Marx generators. The paper describes the new design of the trigger generator.
