诊断开关电源传导干扰的主要性质，分别测量共模干扰和差模干扰，是正确设计电源ＥＭＩ滤波器的第一步。介绍了共模干扰和差模干扰测量的三种方法，并讨论、比较了三种方法各自的优缺点。
Diagnosing the main properties of conducted interference of switching power supplies, measuring common mode interference and differential mode interference, respectively, is the first step in the proper design of a power supply EMI filter. Three methods of measuring common mode interference and differential mode interference are introduced. The advantages and disadvantages of the three methods are compared and discussed.
