EMC测试中的电流注入技术

文章综述了在系统电磁兼容性(EMC)测试中替代直接辐照的电流注入技术的最新研究成果。电流注入技术主要有两种：大电流注入(BCI)和直接电流注入(DCI)。BCI技术主要用于辐射敏感度测试，尤其是测试电缆束对射频耦合的敏感度。DCI技术是一种用在高场强辐射场(HIRF)下系统级EMC安全裕度测试的新技术，研究的热点是其相对自由场辐照的有效性及等效关系。

The Advances in Development of Current Injection Methods for EMC Testing

This paper discusses the research and development of current injection techniques instead of radiated electromagnetic field for system level EMC testing. There are two kinds of current injection techniques: bulk current injection (BCI) and direct Current Injection (DCI). BCI testing can be used to complement radiated susceptibility testing, especially when testing the susceptibility of wire bundles to RF coupling. The DCI technique is being researched as an alternative more efficient technique for the safety margin of system level EMC at high intensity radiated field (HIRF). Many papers are focused on the development of the equivalence and validation of the technique as related to free field illumination..
