开关电源的电磁干扰对电子设备的性能影响很大,因此,各种标准对抑制电源设备电磁干扰的要求已越来越高。对开关电源中电磁干扰的产生机理做了简要的描述,着重总结了几种近年提出的新的抑制电磁干扰的方法,并对其原理、应用做了简单介绍
Switching power supply electromagnetic interference on the performance of electronic equipment, so a variety of standards to suppress the electromagnetic interference power equipment requirements have become increasingly high. A brief description of the generation mechanism of electromagnetic interference in the switching power supply is given, and several new methods of suppressing electromagnetic interference proposed in recent years are emphatically summarized. The principle and application of the method are introduced briefly
