In this article, the influence of multistage synchronous induction coil launcher (SICL) coupling on diode advance conduction was analyzed. The coil current and launching performance of the SICL which is based on the crowbar circuit was also investigated. The thyristor was connected before diode in this multistage SICL system circuit. First, the precise mathematical model for this two-stage SICL was theoretically deduced. The model was to analyze the effects of coils coupling under different trigger timings on diode advance conduction and coil current. Second, the derivation of the model was based on applying the precise mathematical methods of coils coupling to the process of SICL launching. From this analysis, the effects of coils coupling under fixed trigger timing on coil current and launching performance can be obtained. By comparing the MAXWELL finite-element simulation with MATLAB numerical calculation, we were able to estimate the correctness of the precise mathematical model. Finally, experiments were carried out and the results were well consistent with the simulation results.

基于Crowbar电路的多级SICL耦合分析与研究

本文分析了多级同步感应线圈发射器(SICL)耦合对二极管超前导通的影响。还研究了基于 Crowbar 电路的 SICL 的线圈电流和发射性能。在这个多级 SICL 系统电路中,晶闸管连接在二极管之前。首先,从理论上推导出了这种两阶段 SICL 的精确数学模型。该模型旨在分析不同触发时序下线圈耦合对二极管超前导通和线圈电流的影响。其次,模型的推导基于将线圈耦合的精确数学方法应用于 SICL 发射过程。通过该分析,可以获得固定触发定时下线圈耦合对线圈电流和发射性能的影响。通过比较MAXWELL有限元仿真与MATLAB数值计算,我们能够估计出精确数学模型的正确性。最后进行了实验,结果与仿真结果非常吻合。
