摘要: 提出了将传统单个储能电感利用传输线分隔成两部分的新型电感储能脉冲功率驱动源技术方案。理论分析表明，利用传输线电容的耦合延时作用，可有效对调制器输出脉冲波形进行整形，并且可以进一步提高能量转换效率，从而克服传统电感储能脉冲功率源输出波形质量差（类三角波波形）的缺点。基于该思想开展了实验研究，获得了电压约300 kV，电流约20 kA的电子束，并成功驱动S波段磁绝缘线振荡器获得了百MW量级的微波输出。Abstract: A novel inductive energy storage pulsed power source design has been presented, with two energy storage coils separated by a water transmission line. Considering the transmission line as a capacitor, the novel principle circuit was simplified and the discharging formula of the inductor was derived. The formula shows that, the novel technology changes the traditional pure exponentially-decayed discharging waveform into a combination of an exponentially-decayed discharging waveform and a sinusoidally-damped oscillation discharging waveform, which can improve the output waveform and increase the energy conversion efficiency. Based on this theory, experiments have been carried out and an electron beam with a voltage of 300 kV and a current of 20 kA was generated. Several hundreds megawatt micr
