A corona discharge device is provided in which a corona discharge region is formed between the very narrow and small surface area line edges of two electrodes. The electrodes may be generally sheet form and each have a base portion and N protruding portions extending from the base portion (N being an integer and <=1). The protruding portions of the electrodes are shaped and positioned to inter-mate with another to define a serpentine shaped region between the electrodes, wherein edges of protruding portions of one electrode and edges of protruding portions of the other electrode are disposed in parallel to and directly opposite one another so as to form 2N-1 corona discharge region segments therebetween. When the electrodes are energized by a high voltage AC signal a corona discharge is formed in each discharge region segment. Preferably a dielectric wafer lies about half way within each corona discharge region, and is oriented perpendicularly to the plane of the electrodes. When mounted within a chamber, an oxygen containing gas can be fed through the corona discharge regions of the device to conveniently and efficiently generate ozone. The HVAC power circuit which provides the driving AC voltage to the electrodes may also have a corona adjustment level circuit that adjusts the mark-space ratio of the AC voltage.
