| 摘 要： | 开关电源不仅应具有抑制电磁干扰(EMI)的能力,而且它所产生的电磁干扰也必须低于规定的限度,不得影响同一电磁环境中其他电子设备的正常工作。与此同时开关电源还必须符合安全规范(简称安规),这是开关电源能长期稳定工作的可靠保证。

| Abstract: | Switching power supply not only has the ability to suppress electromagnetic interference(KMI) and it generated electromagnetic’ interference must also be less than the prescribed limits,which shall not affect the normal works of other electronic devices in the same electromagnetic environment.At the same time switching power supply must also meet the safety specifications,which is the reliable guarantee for switching power supply to long-term stability. |
