Repetitive Gas-Discharge Closing Switches for Pulsed Power Applications

摘要

Gas-discharge closing switches are the key component of a pulsed power supply. Repetitive gas-discharge closing switches are still the preferred scheme for high-power repetitive pulse power generators in many applications, but their repetition performance depends on the recovery time of the gas insulation medium. This article reviews the existing repetitive gas-discharge closing switches. The basic structure and working principle of each switch are briefly introduced. This article focuses on advances in the study of the factors that impact the recovery characteristics of gaseous insulation in switches. It also presents a survey of methods to improve the performance of gas switches' repetition rate.
