In this research, a diffuse glow discharge generated by a double discharge is used to improve the efficiency of the ozone generation. In this method, corona discharge occures in space between the cathode and the trigger electrode covered with Pyrex glass tube which is set in groove on the cathode. Much initial electrons are generated around the cathode.
In present research, experiments were done using air (O1/N2 mixture) at atmospheric pressure and the discharge repetition frequency was 1[Hz] for all experiments. The maximum ozone concentration generated by that experiment was about 150[ppm]. The average ozone yield was about 400[gO3/kWh] that is much higher than the typical yield, about 100 [gO3/kWh]. The efficiency of energy transfer from stored energy in capacitor C1 to the main discharge was about 40-50[%] at large stored energy.
