传导骚扰测量用人工网络研究

Study of Artificial Networks for Conducted Disturbance Measurement

电子产品在工作时会对外界发射电磁骚扰,这些电磁骚扰会沿着空间和电源线、信号线等导体进行传播。为了维护良好的电磁环境,保证设备或系统工作时不对该环境中的其他设备造成不能承受的电磁骚扰[1],应确保电子产品发射的电磁骚扰在一定限值下。传导骚扰测量就是测量沿电源线、信号线等导体向外传播的电磁骚扰。针对传导骚扰测量中使用的人工网络,介绍了人工电源网络(AMN)和不对称人工网络(AAN),重点分析了AMN和AAN的类别和关键校准参数,并结合实际检测工作,分析了AAN的选型,对于相关人员更好地开展传导骚扰测量具有一定的指导意义。

Electronic products at work will emit electromagnetic harassment to the outside world,and these electromagnetic harassment will be transmitted along the space and power lines,signal lines and other conductors.In order to maintain a good electromagnetic environment and ensure that the equipment or system does not cause unbearable electromagnetic harassment to other equipment in the environment,it is necessary to ensure that the electromagnetic harassment emitted by electronic products is under a certain limit.Conducted emission is used to test the electromagnetic harassment transmitted along the power line,signal line and other conductors.The artificial mains network(AMN)and asymmetric artificial network(AAN)for the artificial network used in conducted disturbance measurement are introduced,the categories and key calibration parameters of AMN and AAN are emphatically analyzed.Combined with the actual detection work,the selection of AAN is analyzed,which is of great significance for the relevant personnel to better carry out the conduction harassment testing.
