Abstract

The characteristics of the triggered vacuum switch (TVS) are obviously influenced by the emission current i e and emission charge of the trigger device. In this paper, an RC charge collector is designed, and the characteristics of emission current i e and collecting charge Q _e of the trigger device are studied. The experimental results indicate that the emission current i e which is produced by the initial plasma has both positive and negative components, and the polarity of the emission current i e depends mainly on the polarity of the bias voltage U Bias . The emission current i e and collecting charge Q _e increase with the increase of the trigger voltage U tr and the bias voltage U Bias . The emission efficient η increases linearly with the increase of the bias voltage U Bias . When the gap distance is 15 mm and bias voltage U Bias is 160 V and trigger voltage U tr is 2.6 kV, the emission efficiency η reaches 6%.
