双路输出超宽谱高功率微波驱动源Tesla变压器

为实现25 GW级双路输出超宽谱高功率微波驱动源的小型化，选择研制了一种与双筒脉冲形成线(Blumlein线)相配一体化的带有开路磁芯的Tesla变压器，作为初级脉冲功率源。进行了Tesla变压器的理论分析，利用简化的磁路模型研究了Tesla变压器初次级线圈电感等电参数的估算方法，给出了Tesla变压器磁芯截面的估算和磁芯制作方法。该Tesla变压器最大输出电压880 kV,充电时间约20 s,耦合系数约0.95,实验结果与理论设计相符。

Tesla transformer for dual-output ultra-wide spectrum HPM pulse generator

In order to realize the miniaturization of the 2×5 GW level dual-output ultra-wide spectrum HPM pulse generator, a Tesla transformer with open circuit magnetic core as the primary power source is developed, which is fixed in the Blumlein pulse forming line. Theoretical analysis of the Tesla transformer is carried out, and the method to estimate the electric parameters such as inductances of the primary and secondary windings by using a simplified magnetic circuit model is presented. The approach to calculating the sectional area of the magnetic core and a fabricating technique of the magnetic core are also described. The Tesla transformer can generate the maximum output voltage of 880 kV, and its charge time and coupling coefficient are 20 μs and  0.95, respectively. The experimental result is in good agreement with the theoretical design.
