Tesla型脉冲源在小型化设计中存在次级线圈绝缘压力大、形成线受磁心及线圈结构限制等问题,三谐振变压器可以有效解决以上问题,为此笔者研制了1台基于非闭合磁心的三谐振型高压脉冲产生装置。通过对三谐振脉冲变压器无损电路的分析,给出了在高耦合系数条件下采用第1峰进行充电的设计思路及方法。在已有GW级Tesla变压器基础上,研制了1台基于三谐振脉冲变压器的脉冲功率源。实验结果表明:系统最大工作电压约为280 kV,为次级线圈电压的1.6倍,输出脉宽2.7 ns。
Tesla-type pulse source in the miniaturization design of the secondary coil insulation pressure, the formation of the line by the core and the coil structure constraints and other issues, three resonant transformer can effectively solve the above problems, for which I developed a non-closed core-based three Resonant high voltage pulse generator. Through the analysis of the non-destructive circuit of three resonant pulse transformer, the design idea and method of using the first peak for charging under the condition of high coupling coefficient are given. Based on the existing GW-level Tesla transformer, a pulsed power source based on three resonant pulse transformers was developed. The experimental results show that the maximum operating voltage of the system is about 280 kV, which is 1.6 times the voltage of the secondary coil and the output pulse width is 2.7 ns.
