Investigation and Simulation of Dielectric Barrier Discharge under High Frequency and High Voltage

With the experimental facility and measurement system of dielectric barrier discharge(DBD) ,this paper studied the characteristic of plasma assisted combustion(PAC) actuator discharge under different thickness dielectric layers,applied voltage and air gap distance.On the basis of the experimental data,the parameters such as the terminal voltages and the discharge current on the air gap clearance are calculated according to an equivalent circuit.The results show that,the thickness of medium strongly influences discharge pulse times;with the increasing of applied voltage,discharge pulse times increases,and discharge starting time continuously brings forward;while with the decreasing of air gap distance,actuator discharge intensity distinctly enhances,and the discharge is more uniformity.
