摘要
电流注入探头作为一种高效的大电流注入技术广泛运用于电磁兼容性试验。提出了电流注入探头的两种电路模型:集中参元电路模型和分布式传输线模型。并将实测的探头参数与两种仿真模型的结果对比,表明分布式传输线模型与实际情况更为吻合。
Injection probe is a kind of valid and effective Bulk Current Injection (BCI) technique, and several international standards for Electromagnetic Compatibility (EMC) refer to this approach. In this work, a lumped-parameter circuit model and transmission line model are discussed. The simulated models are compared with the experimental characterization of the injection probe, and the result shows the transmission line model is more identical with actual conditions than the lumped-parameter circuit model.
