Abstract

The applications of the pulse power technology are expanding and the necessity of a large current switch as a core component of pulsed power is increasing. A trigger gap switch composed of three electrodes was fabricated and the discharge characteristics were studied according to the change of the pressure, the shape of the main electrode, and the gap distance when the trigger pulse was applied. As a main result, the stable operation range was confirmed through the discharge inception voltage according to the gap distance and electric field analysis was performed in the same structure to confirm the electric field value of the discharge inception voltage.
