摘　　要：电磁兼容(EMC)分析和预测是EMC设计的最新阶段,其中系统级电磁兼容性分析是保证系统满足电磁兼容性的一个重要步骤。目前系统电磁兼容性分析主要是基于电磁屏蔽拓扑的分析方法,该方法应用于系统内电磁兼容性遇到一些困难。为了更清晰地分析系统内电磁兼容性,提出了基于端口数据的系统级电磁兼容性分析方法,该方法分析系统内各部件端口之间的耦合关系,画出耦合关系图,然后根据端口的干扰数据(测试、计算或标准规定的数据)和传递函数分析系统的电磁兼容性。Analysis and prediction of electromagnetic com EMC design. The system EMC analysis is an important step patibili in the （EMC） is the new phase in the system. The existing system EMC method is mainly based on EMC shielding topology. But it has some difficulties when used in the intersystem analysis. To analyze the intersystem EMC more distinctly, the method based on port data is presented. The coupling relation between ports is analyzed and the corresponding figure is drawn in the method. EMC of the intersystem can be analyzed by coupling-function and the interference data of port, which are obtained from test,calculation or specified standard.
