| 摘 要： | 利用电路模型分析了用于保护设备的辅助小功率开关电源传导性电磁干扰产生的原因、传播途径及等效电路，介绍了抑制开关电源传导发射的滤波器设计原则、工作原理和结构。利用德国罗德施瓦茨公司的场强接收机实际测量了未加滤波和加滤波时电源线上的传导发射值，实验证明合理设计滤波器对抑制开关电源传导发射有非常明显的效果。

| Abstract: | The paper analyses the reason, the transmitting track and the equivalent circuit of conducted EMI induced by auxiliary switch power supply of measuring relays and protection equipment by circuit model. According to characteristics of EMI signal, the principle, design and structure of the EMI filter using conducted EMI suppression are introduced. The authors measured the value of conducted EMI of power wire respectively using EMI receiver without and with filter. The experiments showed that the good filter could suppress switch power supply conducted EMI. |
