大气脉冲气体放电需要将持续时间非常短的高压脉冲传送到电极。而且，极短脉冲的大气气体放电通常是高阻抗负载。基于感应储能 (IES) 的脉冲功率技术适合此应用。在本文中，我们提出了一种带有 IES 的重复脉冲高压发生器。它采用半导体开启开关，结合磁性开关和绝缘栅双极晶体管。实验测试采用30厘米长的板刀放电负载进行。在空气中间隙距离为 1 cm 时，可获得约 50 kV 的输出电压和约 10 ns 的脉冲持续时间。发生器的运行重复频率高达 250 Hz。已鉴定出均匀放电等离子体。
Atmospheric pulsed gas discharge requires very short duration high-voltage pulse delivered to the electrodes. Moreover, atmospheric gas discharge of very short pulse is usually a high impedance load. Pulsed power technology based on inductive energy storage (IES) is suitable for this application. In this paper, we present a repetitive pulsed high-voltage generator with IES. It uses semiconductor opening switch, combined with magnetic switches and insulated-gate bipolar transistors. Experimental tests were carried out with 30-cm-long plate-to-knife discharge load. An output voltage of ~ 50 kV with a pulse duration of ~10 ns was obtained for a gap distance of 1 cm in air. The generator has been operated at a repetition rate up to 250 Hz. Uniform discharge plasma has been identified.
