ABSTRACT:
The circuitry for operating a glow discharge path (GES) comprises a bridge circuit (BC) comprising a polarity switch (S1) and an ignition pulse circuit (ZIS1) in a first bridge branch (B1) and a polarity switch (S2) and an ignition pulse circuit (ZIS2) in a second bridge branch (B2). The glow discharge path (GES) formed between two electrodes (E1, E2) is located in the transverse branch of the bridge circuit (BC). For changing the polarity of the glow discharge path (GES), the polarity switch (S1) of the one bridge branch (B1) can be operated together with the ignition pulse circuit (ZIS2) of the other bridge branch (B2). Thus, each of the two electrodes (E1, E2) of the glow discharge path (GES) can be used as a cathode. The cathode of the glow discharge path is cleaned by the impinging ions.
