基于固态化磁开关、低阻抗脉冲形成网络和感应电压叠加等关键技术,提出了一种固态化高功率长脉冲驱动源技术方案,该方案充分利用了绝缘规律,可实现模块化设计,具备提高系统稳定性、可靠性、重复频率和长时间运行的潜在优势。目前,针对系统方案进行了电路模拟计算,研制了各关键子系统,开展了全系统的初步联合实验,在假负载上输出了功率2.1 GW、脉宽约170 ns的高压脉冲,验证了技术方案的合理性。

A solid state high power long pulse generator was designed based on the technology of the magnetic switch, low impedance pulse forming line, and inductive voltage adder, which fully profited from the insulation rules, implemented modularization, and could improve the average power, stability, credibility and life of the whole system potentially. The circuit model and the key sub-systems were developed to examine the whole system. Experimental researches were carried out on the whole system. The preliminary results achieved on a dummy load show that the output pulsed power is about 2.1 GW and the pulse width about 170 ns, which verifies the design concept.
