10，电导率：又叫电导系数。是衡量物质导电性能好坏的一个物理量。其数值大小是电阻率的倒数。用字母γ表示,单位为S/m(西/米)。11，自感：当闭合回路中的电流发生变化时,由这个变化电流所产生的、穿过回路本身的磁通随之发生变化,在这回路中将产生感生电动势,这种现象称为自感现象。这种感生电动势叫作自感电动势。穿过回路所包围面积的磁通与产生此磁通的电流之间的比例系数,叫作回路的自感系数,简称自感。其数值等于单位时间内,电流变化一个单位时由于自感而引起的电动势,用字母L表示,单位为H(亨利)。

任何电磁干扰的发生都必然存在干扰能量的传输和传输途径。通常认为电磁干扰传输有两种方式：一种是传导传输方式；另一种是辐射传输方式，电子设备工作频率越来越高，不加抑制时，可能会通过上述路径干扰到其它电子设备的正常运行，这是我不希望的。在电路设计时都会加入抑制EMI的元件来开抑制对外和外面对自身设备的干扰，我们以下面这个电路为例图中L2为共模电感，共模电感的作用可根据右手定则来权释。当开关电源的频率为100K时，假设它们在50~150K时有较高的EMI发射值（这个是需要设备实际来调整的），假设的他的截止频率fo为150KHz，配套的电容CY=CY3=CY4=222PF，共模电感值根据公式可以得出：共模电感与电容构成的EMI电路，在开关电源中都基本上大同小异，根据实际的开关频率与EMI抑制效果作适当的调整。
