Discharge characteristic of the high concentration ozone generator in a narrow discharge gap DBD are studied by using q-v figures. The results show that the ozone generator has the characteristic of Zener Diode. Some discharge parameters, such as the equivalent capacitance of the dielectric layer, the equivalent capacitance of the discharge gap and the reduced electrical field of the discharge gap, will change with the applied voltage and frequency, and will affect ozone generating concentration and the efficiency. As a result, it is highly important to choose correct discharge parameters for improving performance of the ozone generator.
