摘要
文中采用电磁场数值模拟的方法对开关电源差模电流的辐射干扰进行了模拟,并对模拟的结果进行分析,得出了差模电流辐射的基本特性和闭合印制线回路的变化对它的影响。
Radiated emission interference caused by differential mode current in SMPS is simulated by using the numerical method in the electromagnetic field, and its result is analyzed, from which are derived the basic characteristic of radiated emission caused by differential mode current and the effect of the variation of closed printed circuit loop on the emission.
