摘要
大气压下介质阻挡放电需要快前沿纳秒级高压脉冲来产生低温等离子体,为此,设计了可以应用于介质阻挡放电带磁芯复位的单级磁压缩脉冲发生器,主要由充电系统、中间储能、磁开关与升压变压器组成。基于半导体驱动的深入研究,由555定时器组成的脉宽可调的方波发生器和集成单稳态触发器SN74123组成的延时电路产生频率、脉宽和相位可调的单次或重频触发信号,经过基于IR2110的半桥电路驱动IGBT。实验选取铁基纳米晶磁芯进行测试,根据磁性材料的物理特性参数,计算出磁开关饱和时间与匝数。试验结果,在200Ω电阻负载上输出幅值15 kV、上升沿60 ns、半峰宽150 ns的窄脉冲,前沿压缩倍数为19.2。
The dielectric barrier discharge under atmospheric pressure needs the nanosecond high voltage pulse with fast rise time to generate the low temperature plasma. Therefore, a single-stage magnetic compression pulse generator with magnetic core reset that can be applied to dielectric barrier discharge is designed. It is mainly composed of the charging system, intermediate energy storage, magnetic switch and boost transformer. The delay circuit composed of the pulse width adjustable square wave generator and the integrated single-steady-state trigger SN74123 composed of the 555 timer generate the frequency, pulse width and phase adjustable single or double frequency trigger, and drive IGBT through the half-bridge circuit based on IR2110.The experiment selects the iron-based nano-crystalline magnetic core for testing, and the saturation time and turns of the magnetic switch were calculated according to the physical characteristic parameters of the magnetic material. Experimental results show that a narrow pulse with 15 kV peak voltage, 60 ns rise time, and 150 ns full width at half maximum is obtained on a 200 Ω resistive load. The compression ratio of the rising edge is 19.2.
