Results of research of starting modes for small-sized triggered vacuum switches (TVS) at fast-rising commutated currents are presented. The research was carried out for sealed-off TVS with discharge gaps of about 1 mm for switching current rise rates of more than 1010 A/s. It was shown that the stable mode of TVS turn-on was disturbed by short-time current falls accompanied by high voltage spikes...
The paper describes the results of tests performed to obtain interrupting capability parameters of triggered vacuum switches. The switches used in all tests had sealed-off designs with lengths of the main discharge gaps of about 1 mm. The experimental conditions covered a range of peak currents of 1 to 5 kA with current fall rates up to 5 kA/μs. The upper level of commutated voltage (∼5 kV) was limited...
Non-thermal plasma is a promising technology for the generation of ozone and removal of exhausted fuel gases. Energy efficiencies become more and more important in many industry applications. Discharge excited by nanosecond pulsed power is said to be one of the most efficient method1,2. In this study, a compact 4 stages stacked blumlein pulse forming line based power source will be introduced to generate...
The plasma opening switch (POS) is a pulsed-power switching technology that has been developed for inductive-energy-storage applications.[1] During the conduction phase of the POS, the discharge current initially flows in a plasma that is injected between the anode and cathode prior to the arrival of the main pulse. Lorentz forces act on the current-carrying plasma to distort the plasma distribution...
High-voltage switches capable of operating at high speeds and over a wide range of voltages and energies are used in a wide variety of applications in material science and plasma physics. This paper discusses the fabrication and characterization of a novel high-voltage shock switch. The structure has been designed to operate as a fast-turn-on, low-impedance device. The switch is a planar structure...
