“…All the above results are tabulated in Table III. During simulations, as the switch interelectrode distance reduces, the prepulse magnitude increases, confirming the theoretical and experimental results reported in [13] (Fig. 10).…”

“…To study the dependence of rise time on various switch parameters, the fifth-order model for the output voltage is approximated to second order by neglecting the peaking capacitance value Cp and considering the voltage across the peaking capacitor V Cp and given by (12). The natural frequency of oscillation ω n and the damping coefficient ξ obtained from (12) is given in (13) and (14), respectively, using which the real and imaginary parts of damped frequency of oscillations are computed from (15) and (16) V LOAD (s) The time taken to reach the peak value (T p ) is then given by…”

This paper discusses the development and analysis of a transfer function model of the peaking capacitor and peaking switch for an input from Marx generator and an output across load. The effect of variations of gap distance, pressure, peaking capacitor, and the input pulse rise time on the rise time of the output pulse is simulated using this model. For a given geometry, the modeling gives an optimum input pulse rise time and the effect of variation of peaking capacitor on various output parameters. The results obtained from modeling are validated with the experimental results.

Abstract-A methodology for electromagnetic simulation of initially charged structure with a discharge source (ICSWDS) has been investigated. The ICSWDS can be applied to a lot of areas such as high power electromagnetic (HPEM) radiators. As a method of electromagnetically simulating the ICSWDS, converting initially charged structures into equivalent transient structures and modeling discharge sources by using step voltage sources have been found. A Blumlein pulse forming line (PFL) has been simulated, manufactured and tested to validate this approach. A measured waveform from the test has a good agreement with a simulated waveform.

“…Yet, the blowsystem is usually large in size and expensive. Hydrogen with its high thermal diffusivity and high molecular speed allows the recovery time to be an order of magnitude faster without refer to gas blow [2][3][4] and it is widely used in Ultra Wide Band(UWB) [5][6][7]. In the references above ， the investigations of hydrogen insulating recovery characteristic is limit to low voltage or short pulse width.…”

Hydrogen has the best recovery property compared with other gases such as N2 and SF6, which has a potential application on the multi-pulse and high repetitive pulse modulator. This paper introduced a high pressure hydrogen gas switch with two cylindrical structures. The stress of the switch under high pressure is analyzed theoretically, and the pressure of hydrogen gas in the switch was hydrostatically tested up to 30atm. Such a switch was employed on high power pulse modulator with water dielectric PFL (Pulse Forming Line). At the switch breakdown voltage of 520kV and the pressure of hydrogen 12atm, a 230kV, 31kA and 60ns during time electron beam is obtained at the field-emission diode. Furthermore, when the switch was filled in different gases such as H2, N2, SF6, the rise times of diode voltage of modulator have been compared at the switch breakdown voltage 400kV. The results show that the rise times of diode voltage is reduced obviously when hydrogen is used as the dielectric of spark gap switch.
