Trigger arrangement for a Marx generator

摘要

In trigger/firing arrangement in a Marx generator comprising n stage capacitors—n being a natural number greater than 1-, the same amount of spark gaps and 2(n−1) charging branches, with the spark gaps operating in a self-breakdown mode, the trigger-/firing arrangement comprises at least a pulse transformer connected to an 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 is disposed, whose output winding operates during charging as a charging winding and whose input winding is connected to the pulse generator in such a way that the voltage pulse generated with this pulse transformer during triggering of the pulse generator is added to the charge voltage of the associated stage capacitor and, with a corresponding polarity, generates an over-voltage sufficient for initiating self-breakdown at this spark gap.
