Patent ID: 7170198

Claim:
A trigger/firing arrangement in a Marx generator comprising n stage capacitors—n being a natural number greater than 1-, the same amount of switches/spark gaps, and 2(n−1) charging branches, with the spark gaps operating in a self-breakdown mode, the trigger-/firing arrangement comprising at least a pulse transformer connected to a pulse generator in at least one of the charging branches of the Marx-generator, which, with the associated stage capacitor, bridges a spark gap—except for the output end spark gap-, a pulse transformer connected, such that the output winding thereof operates during charging as, or also as, a charging winding/inductivity and the input winding thereof being connected to the pulse generator in such a way that the voltage pulse generated with this pulse transformer during ignition/triggering of the pulse generator is added to the charge voltage of the associated stage capacitor and, with a corresponding polarity, generates during the increase of the voltage pulse an over-voltage sufficient for initiating self-breakdown at this spark gap.
