摘要
开关电源的电磁干扰对电子设备的性能影响很大。因此,各种标准对电源设备电磁干扰的要求已越来越高。在开关电源产生的两类干扰中,传导干扰由于经电网传播,会对其它电子设备产生严重的干扰。本文着重总结了几种近年来提出的抑制电磁干扰的新方法,并对其原理、应用作了介绍。
Because of the electromagnetic interference（EMI） in power supplies has great effects on electronics equipments, standards and require ments on EMI in power supplies are more and more strict. Conducted interference will spread along the power line, so the effect is very bad. In this paper several new suppression methods are overviewed and summarized.
