摘要: 针对脉冲源+传输线+感应腔和储能电容+固态开关+感应腔两种常见的脉冲感应组元结构,对相同感应腔的腔压波形进行了实验对比和理论分析,推导出了不同组元结构下感应腔中磁芯回路电感量、匹配电阻阻值和感应脉冲幅度间的关系表达式,分析对比了两种组元结构下感应腔电感量和电阻值变化对腔压平顶影响的程度和差异,为低压重频脉冲感应加速组元的参数选择和优化提出建议和判据。Abstract: Circuit models and mathematical expressions are built to analyse how much the circuit parameters of induction cavity affect the flattop of the induction pulse voltage. Two kinds of pulse-power system (PPS) are considered, one is based on the pulse forming lines (PFL) and pulse transmission lines, and the other is based on the capacitors and solid state switches. Much difference appears when the cavity works with different PPS. Using the comparison expressions including capacitance, inductance and resistance of the induction cavity and corresponding PPS, we can determine the circuit parameters of a pulse induction module exactly and easily.
