  • 摘要: 设计一套纳秒量级的脉冲电源,测试结果表明脉冲上升沿为15 ns,脉宽30 ns,输出端串联后最大峰值电压为20 kV,并联后最大峰值电流为340 A。电源频率在50~600 Hz范围内变化且输出脉冲的极性可调节。纳秒脉冲源匹配反应器后产生电晕放电,在相同的电源输出能量下,负脉冲的能量注入效率只有37.4%,而正脉冲为87.3%。当脉冲频率为600 Hz时,反应器功率为59.4 W。以苯乙烯为目标处理物,当能量密度为27.4 J·L-1 时,苯乙烯降解效率达到98.6%。相同能量密度下,负脉冲放电下苯乙烯的去除率最高。
    Abstract: An efficient and reliable pulsed power generator is developed both in circuit principle and design implementation. Experimental results show that the rising edge of the pulse is 15 ns, pulse width is 30 ns. The maximum peak voltage is 20 kV when the output is connected in series, the maximum peak current after parallel is 340 A. The power supply frequency varies from 50 to 600 Hz and the polarity of the output pulse can be adjusted. At the same output energy, the efficiency of negative pulse is only 37.4%, while positive pulse is 87.3%. When the pulse frequency is 600 Hz, the reactor power is 59.4 W. When the energy density is 27.4 J·L-1, the degradation efficiency of styrene reaches 98.6%. At the same energy density, the removal rate of styrene under negative pulse discharge is higher than positive pulse.
