摘要
开关电源本身产生的干扰直接危害着电子设备的正常工作。抑制开关电源本身的电磁噪声, 是开发和设计开关电源的一个重要课题。简要地对开关电源电磁干扰产生、传播的机理进行了介绍, 总结了几种主要的抑制开关电源电磁干扰产生及传播的方法。
The electromagnetic interference (EMI) in the switching power supply has great effects on the nornal operation of the electronics equipments, therefore the standards and requirements on suppressing EMI in switching power supply are more and more strict. A brief introduction about the mechanism of EMI in switching power supply is given at first, and then the EMI suppression methods are overviewed and summarized.
