由于影响240W适配器中的共模滤波器大小的主要原因来自于DCX拓扑所产生高频共模噪声，对此建立针对高频噪声的数学模型。针对多元胞多个噪声源的特点，通过控制的策略减小共模电流噪声。

Since the main factor affecting the volume of the common-mode filter in the 240W adapter comes from high-frequency common-mode(CM) noise, CM current noise model of the high-frequency switch was established and the mathematical equations were obtained. In view of the characteristics of multiple noise sources, a control strategy is used to suppress the CM current noise.
