Influence of Rise Time of Pulse Voltage on Microgap Discharge

Understanding the characteristics of micro gap discharge when applied surge voltage is important for insulation of miniaturized equipment. In this work, a microgap was created using a cone-shaped copper electrode, and an impulse voltage was applied. Light emission of micro gap discharge observed affected by rise time of voltage and investigated the effect on discharge behavior. It was found that the effect of shortening the rise time is greater when the gap length is large.
