| 摘 要： | 针对实验产生等离子体的需求,研制了一种高压微秒脉冲电源,输出电压最大值为30kV,上升沿最小为300ns、脉宽0.5μs。测试结果表明电源的输出特性由负载决定,同时调节输入电压、触发脉宽可以改变电源的输出脉冲。研究了针-针放电负载时,电源重复频率以及针针间隙对于放电模式的影响,并通过研究电源输出随负载的变化来区别不同的放电模式,最后把电源成功应用于介质阻挡放电。

| Abstract: | To meet the requirement of some actual application experiments, a kind of high voltage microsecond pulse generator is developed. The output voltage amplitude is up to 30 kV with a minimum rise time of 300 ns and a pulse duration of 0.5 s. Some tests show that the output characteristics of the generator are determined by the load, and the input voltage and trigger pulse width can change the output pulse. Experiments by a point-to-point gas discharge are used to show the characteristics, the discharge modes can be changed by adjusting the pulse frequency and gap spacing. Different discharge modes can be distinguished by studying the variation of the pulse output with the load. Finally, the generator is successfully used for the excitation of atmospheric-pressure dielectric barrier discharge. |
