DBD is known to generate non-thermal equilibrium plasma even under atmospheric pressure. DBD is suitable for ozone production [4-7]. However, some of ozone generator configurations generate inhomogeneous heating of the dielectric barrier resulting in low ozone production efficiency. Experimental studies regarding the construction of the ozone generator such as electrode arrangements[6-10], dielectric material [11], chamber geometry[12-17], power source construction [18-20], gas type (dry air or oxygen) [11], feed gas flow rate and operation pressure [21] have been extensively studied to obtain an optimal level discharge conditions for highthroughput ozone production. Ozone is created when diatomic oxygen (O2) is exposed to an electrical field or ultraviolet light. Exposure to these high levels of energy causes a portion of the diatomic oxygen molecules to split into individual oxygen atoms. These free oxygen atoms combine with diatomic oxygen molecules to form ozone. DBD ozone chamber is a device which consists of air or oxygen gap between two conductors. One of the two conductors will be coated with a dielectric material. A high Designing of Single Switching DBD Ozone Generator
