A Novel Electrical Model of Dielectric Barrier Discharge for Quasi-Homogeneous Mode and Filamentary Mode

The paper focuses on a novel electrical model of dielectric barrier discharge (DBD) considering both quasi-homogeneous mode and filamentary mode. The proposed model employs the partial discharging fractions to describe the difference between the ideal homogeneous discharge and the quasi-homogeneous discharge, and a RC circuit commutated by an ideal switch to simulate the filamentary discharge. Calculations of several electric parameters are given. Evolutions of conduction discharge current and gap voltage are given. Comparison of simulation results with experiment results is discussed, showing that the proposed model has an accurate and effective performance.
