TL;DR: In this paper, a full-solid state Marx generator based on the full-controlled switch and the spontaneous breakdown gas switch was proposed to solve the problem that the time sequence is hard to control by using a full controlled switch and overcoming the defect of capacity reduction.
Abstract: The invention relates to a full-solid state Marx generator based on a full-controlled switch and a spontaneous breakdown gas switch. The generator comprises a plurality of cascaded full-controlled switch levels and further comprises at least one spontaneous breakdown gas switch level maintaining a cascade relation with the last level of the cascaded full-controlled switch levels, wherein difference between the spontaneous breakdown gas switch level and the full-controlled switch levels is that a full-controlled switch is replaced by the spontaneous breakdown gas switch and the spontaneous breakdown gas switch is a spontaneous breakdown switch apparatus when the voltage drop on the switch is greater than a threshold value; the generator further comprises a load output level maintaining a cascade relation with the spontaneous breakdown gas switch level; the load output level is different from the spontaneous breakdown gas switch level that no isolating apparatuses are arranged, and a load is connected between the spontaneous breakdown gas switch and the negative input end of an energy storage device. The full-solid state Marx generator based on the full-controlled switch and the spontaneous breakdown gas switch can be used for solving the problem that the time sequence is hard to control by using a full-controlled switch and overcoming the defect of capacity reduction, and the output efficiency and reliability of the Marx generator are improved.

TL;DR: In this article, a circuit simulation study of the interaction between a vircator load and three different high-voltage pulse sources is presented, which have previously been studied experimentally, are a Marx generator, a highvoltage system based on a small explosively driven magnetic flux compression generator and a cable based generator.
Abstract: The high-voltage pulse source is a key component in systems that generate high-power microwave (HPM) radiation. Different types of high-voltage pulse sources have different characteristics and interact differently with the radiation source. This paper presents a circuit simulation study of the interaction between a vircator load and three different high-voltage pulse sources. The voltage pulse sources considered, which have previously been studied experimentally, are a Marx generator, a high-voltage system based on a small explosively driven magnetic flux compression generator and a cable-based generator. The circuit simulation models have been validated by different experiments. The different voltage sources generate different shape, amplitude and duration of the voltage pulse. The effect of these differences on electric power deposition in, and impedance of, the vircator are discussed.

TL;DR: In this article, a two-stage spark gap was used to control the predischarge, which produced the ultraviolet-preionization, and to generate a trigger pulse for the Marx bank, which excited the main discharge.
Abstract: In a TEA CO 2 laser a two-stage spark gap was used to control the predischarge, which produced the ultraviolet-preionization, and to generate a trigger pulse for the Marx bank, which excited the main discharge. The time-sequence of the predischarge and the trigger pulse could be reversed so that the main discharge could commence before the preionization process. This set-up has enabled temporal synchronization on the laser performance, or basically the time delay between the pre- and the main discharges, to be investigated from about − 150 ns to 600 ns.

TL;DR: In this paper, the setup, the EMC measures taken, and the results of verification measurements are discussed, and typical results obtained in the research with this instrument are shown as well.
Abstract: A 2 MV lightning surge generator is a powerful source of interference, in particular when the voltage waveform is chopped by a shorting spark gap. We not only do need to protect the sensitive diagnostic electronic equipment that operates on small signals, but we also should guarantee its flawless operation during the discharge. The paper discusses the setup, the EMC measures taken, and the results of verification measurements. Some typical results obtained in the research with this instrument will be shown as well.
