摘要
EMC性能是电子产品重要的性能指标,首先介绍了我国国家军用标准中对电场辐射性能的要求,阐述了一种利用馈通滤波器抑制电子设备电场辐射的设计方法。在此基础上结合应用实例,给出了电子设备电场辐射超标的机理分析、馈通滤波器参数选择方法及实验验证结果。实验表明该方法能有效改善电子设备的EMC性能。
EMC performance is an important character of an electronic device. The demand of electric field radiation in national standard is presented firstly. A design methodology for restraining electric field radiation by feedthrough filter is introduced. Based on all of these, an example is given. The principle of electric field radiation overrun and the means of feed-through filter's parameter choosing are discussed. Finally, the experimental results are given. The experiment shows that this method can improve the EMC performance of an electronic device.
