Characteristics of dielectric barrier discharge

Summary form only given. The frequency characteristics of dielectric barrier discharge (DBD) have been studied for optimizing discharge efficiency. The experiment was performed with various experiment conditions to find the relation between the discharge frequency and power consumption. There is the optimum discharge frequency, which minimizes the consumption of the electrical power. Physically, the optimum discharge frequency means the inverse of the charge build-up time on the dielectric materials. Hence, the optimum discharge frequency depends on the capacitance of a reactor, which is a function of the geometry of the reactor and dielectric materials, and discharge conditions, which depends on the discharge voltage, and gases. From the experimental results, a semi empirical relation on the optimum frequency can be expressed as a function of the discharge gap, dielectric materials, sort of electrodes, and discharge gases.
