要約(日本語): Pulsed atmospheric pressure gas discharge has been studied by using a pulsed high-voltage generator based on a bipolar solid-state linear transformer (bipolar SSLTD) scheme. Taking advantage of the output flexibility of the bipolar SSLTD, we have studied the residual charges phenomenon by consecutive bipolar pulses to a coaxial discharge load consisting of a wire and a pipe. The experiment result shows that for two positive consecutive pulses （< 1000 ns）, the current of the second is usually low than that of the first pulse for the same voltage amplitude. However, a middle negative pulse applied between the first and the second pulse can eliminate this phenomenon. If the amplitude of the negative is appropriate, the current of the second could be higher than the first one. An explanation for this phenomenon has been explored by using a model that considers the effect of residual charge left by the first pulse and the middle negative pulse. The findings obtained by this paper will help us understand the fundamental characteristics of pulsed atmospheric discharge.
