基于二极管断路开关的重频高压纳秒脉冲发生器

Repetitive High-voltage Nanosecond Pulse Generator Based on Diode Opening Switch

  • 摘要: 相比于电容储能型电路,电感储能型电路在高电压、快前沿、短脉宽、高重频脉冲参数输出以及小型化、紧凑化脉冲装置设计方面都展现了显著优势,是一项具有竞争力的低温等离子体驱动方案。但是受到了高频高功率断路开关器件难研制、泵浦电路难设计这2个条件的制约,电感储能型脉冲源在实际等离子应用中的报道仍然有限。为此采用团队研发的二极管断路开关(diode opening switch,DOS),设计了基于IGBT软开关技术和双脉冲变压器的DOS正反向泵浦电路,研制了输出电压幅值为36 kV、前沿为6 ns、脉冲宽度为8.2 ns,重复频率为3 kHz (75 Ω负载)的高压纳秒脉冲源。利用该原理样机成功在大气中驱动了板-板电极等离子体放电。该拓扑结构给电感储能型电路的设计提供了可以参考的方向,对进一步发展低温等离子体驱动源具有借鉴意义。

     

    Abstract: Compared with capacitive energy storage circuits, inductive energy storage circuits exhibit significant advantages in pulse parameter (high voltage, short front time, short pulse width, high repetition frequency) and pulse device design (miniaturization, compactness), thus the adoption of inductive energy storage circuits is a competitive low-temperature plasma drive solution. However, the reports of inductive energy storage pulse generators in plasma applications are still limited due to the difficulty in developing high-frequency, high-power opening switches and designing pumping circuits. In this paper, a high-voltage nanosecond pulse generator is developed, which has an output voltage amplitude of 36 kV, a front time of 6 ns, a pulse width of 8.2 ns, and a repetition frequency of 3 kHz (75 Ω load). It employs a diode opening switch developed by our team and a DOS pumping circuit based on IGBT soft switching technology and cascaded pulse transformers. A plate-plate electrode plasma discharge is successfully driven in the atmosphere using the prototype. The topology proposed in this paper is meaningful for the design of inductive energy storage circuits and low-temperature plasma drive generators.
