摘　　要：使用电路模拟软件PSpice对Tesla变压器初级等效回路进行了仿真,得到了不同参数下的分支回路电流分布。研制了4个具有柔韧性的空心Rogowski线圈,用于测量初级回路中多个分支回路的电流。对2台脉冲功率源的初级电流进行了测量,发现电流分布并不均匀。将电流峰值最大的分支回路中的电容值减小到原值的1/2,可使该分支回路的电流峰值减小43%。通过优化初级电流分布,可以抑制电流过快增长,防止可控硅因电流扩散太慢而烧毁。The circuit simulation software PSpice was used to analyze the primary equivalent circuits of Tesla transformers,and the currents of branch circuits with different parameters were calculated.Four flexible air-cored Rogowski coils were made to measure the currents for two pulse power generators.The results show that the primary currents in different branch circuits are different for both generators.When the capacitance of the branch circuit with the highest peak current is reduced by half,the current of this branch circuit will be re-duced by 43%.With optimized primary current distribution,the silicon controlled rectifier of the Tesla transformer can be prevented from damaging due to rapid increase of the primary current.
