Abstract: A spark gap arrangement comprises a triggerable spark gap (TF) and a trigger circuit (TRG), which comprises a first and a second charge store (C1, C2), a first resistor (R1), a triggerable dissipation element (SF, SF3, TD, TH) and a transformer (T1). The trigger circuit is set up to intermediately store the energy of an input pulse supplied to the input side of the trigger circuit (TRG), wherein storage takes place at least by means of the first charge store (C1). A part of the stored energy is transferred to the second charge store (C2) via the first resistor (R1). The triggerable dissipation element (SF, TD, TH) is set up to turn on on the basis of a voltage across the second charge store (C2) and to discharge the first charge store (C1) via a primary side (T11) of the transformer (T1). In this case, a secondary side (T12) of the transformer (T1) is connected to a main electrode (HE) of the triggerable spark gap (TF) and to a trigger electrode (TE) of the triggerable spark gap (TF).

Abstract: In an embodiment a process for producing ozone includes applying an input voltage to an input area of a piezoelectric transformer so that a high voltage is generated in an output area of the piezoelectric transformer, wherein the piezoelectric transformer is operated in a pulsed manner such that phases in which the input voltage is applied to the piezoelectric transformer and phases in which the input voltage is not applied to the piezoelectric transformer alternate at regular intervals and surrounding the piezoelectric transformer with an oxygenic process gas so that the ozone is formed from the process gas by the high voltage generated in the output area.
