摘要: 设计了一台基于分数比可饱和脉冲变压器的全固态脉冲驱动源，其核心部件为分数比可饱和脉冲变压器，用来实现固态磁开关、脉冲调制、电压升压等功能，再借助Marx技术、磁开关技术和反谐振网络调制技术建立全固态脉冲驱动源，初步实验结果表明当直流电源提供100 V的充电电压时，该全固态脉冲驱动源可输出14.4 kV左右的准方波信号，脉宽约194 ns，验证了该技术方案实现输出百纳秒准方波信号的可行性，为建立百MW长脉冲信号输出的全固态脉冲驱动源模块提供了设计思路。

Abstract: This paper presents the design of an all-solid state pulse generator based on a fractional-turn ratio saturable pulse transformer which, as the key component, takes the roles of magnetic switch, pulse forming device, voltage boosting device, etc. Preliminary experimental results show that a quasi-square pulse with the amplitude of 14.4 kV and the pulse width of 194 ns are obtained while the DC voltage source supply is 100 V. Hence, it is feasible to apply this technology to construct a generator outputting pulses with the pulse width of several hundred nanoseconds. This study can provide a guidance to construct a MW level solid state pulse generator module. -
