Abstract：To take advantage of the potential of dielectric barrier discharge (DBD) load, a high-frequency pulse excitation is selected as the excitation waveforms and the load current amplitude of the first discharge as the optimization objective. Based on the method of response surface center combination design, a mathematical model is built to analyze the effects of dielectric barrier layer thickness, applied voltage amplitude, applied voltage rising and falling time and the relative permittivity on the load current amplitude of the first discharge, optimizing the characteristic parameters of dielectric barrier discharge load. The results show that the influence on the DBD load current is in descending order of dielectric barrier layer, applied voltage amplitude, applied voltage rising and falling time, the relative permittivity. Under these conditions, the maximum load current amplitude is 8.692A when the applied voltage rising and falling time is 200ns, the applied voltage amplitude is 4kV, the thickness of dielectric barrier layer is 1mm and the relative permittivity is 8.
