| 摘 要： | 采用Ansoft公司的Designer软件对微机开关电源PCB进行了电磁兼容仿真分析，建立微机开关电源PCB双面板实体模型，各项计算参数并进行计算仿真，得到频点为0．01GHz，0．11GHz，0．51GHz，1GHz时PCB的近场分布图，根据近场分布图分析PCB的电磁兼容性，仿真所得近场分布图对电路的合理设计和布局有重要指导意义。

| Abstract: | With the help of the software ANSOFT Designer, the PCB double-side printed board of computer switching power supply was simulated and analyzed. The near field plots were got on 0.01GHz, 0.11GHz , 0.51GHz and 1GHz. According to the plots, the EMC of the PCB was analyzed. It was conduced that the simulated near field plots are important to circuits design and places. The method could be referred to the EMC simulation analysis of multi-layers printed board. |
