对同轴型特斯拉变压器作为脉冲驱动源方案的强电磁脉冲模拟装置，对特斯拉初级绕组开展同步注入是提升输出效果的有效途径，对电磁脉冲模拟装置性能优化具有重要意义。面向典型同轴型特斯拉变压器初级注入结构，研究初级绕组在不同注入条件下的电流分布状态和电阻、电感参数，分析多路注入的优势与参数要求。在反极性电容放电型触发器的基础上，建立触发仿真模型，分析回路隔离参数对于触发效果的影响，隔离宜采用电容隔离的方式，且容值应远大于开关结构电容值。多路注入能显著降低初级绕组阻值，提升电流分布均匀度，降低初级绕组电感，有效提高输出效率、降低磁芯重量。

For the strong electromagnetic pulse(EMP) simulation device using a coaxial Tesla transformer as a pulse driving source, synchronous injection into the Tesla primary winding is an effective way to enhance the output effect, which is of great significance to optimize the performance of the EMP simulation device. In this paper, focusing on the primary injection structure of a typical coaxial-type Tesla transformer, the current distribution and corresponding resistance and inductance parameters of the primary winding under different injection conditions are studied, and the advantages and parameter requirements of multiple injections are analysed. Based on the reverse-polarity capacitor-discharge trigger, the trigger simulation model is established to analyse the influence of loop isolation parameters on the triggering effect, and it is appropriate to use capacitive isolation, and the capacitance value should be much larger than the capacitance value of the switching structure. Multiple injections can significantly reduce the resistance value of the primary winding, improve the uniformity of current distribution, and reduce the inductance of the primary winding, in order to improve the output efficiency and reduce the weight of the magnetic core.
