The efficiency of ozonizers using silent discharge is very low compared with the theoretical value. Although many studies have attempted to improve the efficiency of ozonizers, we cannot expect to do so without changing the process of ozone generation. In this study, two high voltages are applied to an ozonizer which has three electrodes (central, surface, and outer electrodes) arranged coaxially, and the phase difference between applied voltages can be changed. The silent and surface discharges are superposed in the same space of the ozonizer. This paper considers the optimum experimental conditions leading to improved efficiency of an ozonizer using the discharge superposition method. It is found that when two kinds of discharges are superposed while using the central electrode as a common‐ground electrode, the maximum ozone yield efficiency is obtained, especially at a phase difference of about 180°. However, when using the surface electrode as a common‐ground electrode, the ozone efficiency is higher at phase differences of about 90° or 270° than at other angles. © 1998 Scripta Technica, Electr Eng Jpn, 126(1): 1–6, 1999
