a method and apparatus for producing gas discharge reactions in which a reaction gas is at least partially oxygenated after being taken through a discharge channel . in order to produce ozone by means of an electric discharge , the discharge channel has applied thereto an electric alternating voltage signal consisting of a sinusoidal potential with positive and negative peak values minimally below the firing potential of the discharge channel , and of alternating voltage impulses superimposed on the sinusoidal potential essentially at the respective maximum and minimum values , in order to achieve an exalted potential above the firing potential to enable a discharge reaction . an ozonizer implemented in this way is also disclosed .
