“…A high repetition rate hydrogen spark gap has been described in [9]. Rahaman et al have investigated the spark gap discharge in the regime of very high repetition rate exceeding 1 MHz [10]. Results of this investigation confirm the effect of the residual plasma left in the switch gap after the preceding discharge.…”

The ultrawideband (UWB) system has been a subject of research in the last few decades due to its utility in various highpower electromagnetic applications. Effectiveness of the UWB system, for the targeted performance, is expressed mainly in terms of the intensity and the frequency spectrum of the radiated field. If the system is simultaneously meant for high-energy output with good pulse repetition rate and jitter then the performance of the source of the UWB system, i.e., the pulsed power system, and in particular, the switch becomes extremely important. This paper presents the work carried out on such a UWB system with focus on the experimental investigations performed on a 50 kV pulsed power system. The switch of the pulsed power system is designed to use various dielectric gases, such as dry Air, N 2 , SF 6 , and a mixture of these gases as the switching media at varying pressures which are above and below atmospheric pressure levels. For gas pressures above the atmospheric pressure level, the relationship between the switch breakdown voltage and the gas pressure as well as between the rise time and the gas pressure have been studied. Rise time performances of the switch for various pure gaseous media have been estimated. Jitter and shot life performance of the switch for N 2 and SF 6 as the switching media have also been studied. Effect of shot life on the switch jitter has been evaluated for N 2 filled switch for a shot life of 10.8 × 10 6 shots. In case of switch filled with subatmospheric pressure SF 6 gas, the rise time as a function of pressure has been characterized up to a voltage level of 45 kV. The Paschen's curve for the subatmospheric pressure levels is also derived from the results.Index Terms-High-power electromagnetics (HPEM), pulsed power system, switch, ultrawideband (UWB).

“…The switches of the PPG in water treatment often have gas switches, semiconductor switches, and magnetic switches. The gas switch is usually spark gap switch that is not only suitable for high power pulses, but also triggered more accurately [30][31][32]. However, it has the disadvantages of complicated design, high cost and short service life.…”

Water treatment is one of the most important issues for all walks of life around the world. Different from the conventional water treatment technology, the advanced power electronic pulse technology has unique features and advantages for the modern water treatment. Unfortunately, there is no literature reported to describe them in a comprehensive and systematic way. To fill this gap, an overview of modern power electronic pulse generators (PPGs) for water treatment is presented. This paper, for the first time, classifies the different types of PPGs from the viewpoint of pulse formation. Each of them is discussed, and the advantages and disadvantages are compared and summarized. Aside from that, this paper presents the development and trend of the pulse generators suitable for the specified water treatment processes such as electrolysis, sterilization, and discharge degradation. Finally, a list of more than 100 relevant technical papers is also appended for a quick reference.

Fast recovery switches are never ending demand in pulse power applications. This study uses a two-pulse method to determine the voltage recovery times of gas spark gap switch with argon gas. First pulse is applied to the spark gap to over-volt the gap and initiate the breakdown (FPBDV) and second pulse is used to determine the recovery voltage of the gap (SPBDV). A double pulse generator capable of generating 40 kV peak pulses with a repetition rate of 100 kHz was developed. Recovery Experiments has been conducted for 2mm and 3mm gap length between 0-2 bar pressure range with argon gas as dielectric medium. A sparkgap chamber of which electrodes are of rogowsky profile type, made up of Stainless steel material and thickness of 15mm are used in the recovery study. Pressure has significant effect on the recovery of the spark gap. It is observed that time taken for complete recovery without gas flow techniques is around 1s.
