摘　　要：弧焊电源工作时产生的传导骚扰,不仅会影响设备本身的正常工作,还可能会对同一电网中其他用电设备产生干扰.针对常见的几类弧焊电源进行了传导骚扰发射试验,分析了弧焊电源中传导骚扰的产生机理,提出了传导骚扰抑制方案,通过滤波器拓扑结构和元件参数的选择对弧焊电源进行整改,试验结果显示满足IEC 60974—10中对弧焊电源传导发射的限值要求.The conducted emission generated by arc welding power source not only may affect devices connect- ed in the same main supply, but also may result in mal-function of itself. In this paper, many types of arc welding power sources were tested for conducted emission. The mechanism of conducted emission is analyzed and the suppression method is developed. The re-design of arc welding power source can meet the conducted emission requirement of IEC 60974-10 and has been verified by experiments.
