Abstract
In recent years, surface dielectric barrier discharge (SDBD) sustained by pulse power supply has been widely investigated due to its high efficiency and fast response. In this paper, in order to obtain the effect of the electrode length, dielectric thickness, and electrode width on the characteristics of SDBD driven by microsecond-pulse generator, experimental investigation on the SDBD actuator using a dielectric barrier of epoxy glass cloth is performed. The experimental results showed that both the current amplitude at the rising edge of the applied voltage and the consumption energy increased with the electrode length. Moreover, dielectric thickness slightly affected the displacement current, while the consumption energy decreased when the dielectric thickness increased. Furthermore, when the electrode width increased, the current at the rising edge of the applied voltage increased, but it would reach the saturation when the electrode width exceeded 3 mm. Both the instantaneous power and the consumption energy increased with the electrode width. The experimental results can provide reference for the optimal design of the SDBD actuator driven by microsecond pulses.
