摘要
针对ISO 11452-4:2011中规定的管状电波耦合器(TWC)法和大电流注入(BCI)法,在试验设置、校准方法、干扰强度等多方面进行比对研究。以车载LED灯作为模拟试验样品,对两种方法的试验效果进行比对分析,得出了TWC法在400 MHz以上干扰效率较高的技术结论。最后给出了有关TWC法和BCI法适用范围的合理建议。
Study and analysis was made on the international standard ISO 11452-4：2011. Comparative study was focused on the TWC method and BCI method based on the standard, with respect to the test setup, calibration method, immunity test level ect. A vehicle LED lamp was used as a dummy sample to perform comparative analyze on the interference effectiveness of the two different methods. A conclusion was drawn that TWC method is more effective at the frequencies above 400MHz. And finally, a technical suggestion was given for the appropriate application range of TWC and BCI method.
