摘要
开关电源技术是一项综合性技术,其电磁干扰问题及与其他电子设备的电磁兼容问题已成为人们关注的热点。本文对开关电源电磁干扰的产生、传播机理进行了简要介绍,并从电路结构、EMI滤波、屏蔽、印制电路板抗干扰设计等几个方面,对开关电源电磁干扰的抑制措施进行了分析讨论。
A brief introductoin about the mechanism of EMI in switching power supply is given, and then the suppression measures for electromagnetic interference in switching power supply from design aspects of circuit, EMI filtering, shielding, anti-interference in PCB were analyzed and discussed.
