摘　　要：研制了一套峰值650kV、脉宽2ns的窄脉冲发生器,具有结构紧凑、体积小巧、便于移动和产生优质的纳秒高压脉冲等优点。该发生器基于三谐振脉冲变压器原理和脉冲形成压缩实现窄脉冲输出,采用紧凑双锥形绕组铁芯变压器、LC调谐回路和27pF,30Ω脉冲形成线组成三谐振回路,油介质自击穿开关导通后在负载上获得高压脉冲。实验结果表明,该窄脉冲发生器可在80Ω电阻负载上输出脉冲峰值约650kV,脉宽约2ns,与理论分析的结果相吻合。A compact 650 kV, 2 ns high voltage pulse generator is developed. The specialties in principle and structure are described. It can generate narrow pulse by using a triple resonance pulse transformer and a pulse forming line. A compact conical double winding silicon-steel magnetic core transformer is developed. The circuit of the triple resonance pulse transformer is made up of the transformer, LC tuning circuit and the 27 pF, 30 t2 pulse forming line. The narrow pulse generator is compact and port able. The experimental results show that the compact design is feasible and can deliver more than 650 kV onto a 80 t2 load with 2 ns pulse width when the oil switch is closed.
