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.Abstract: 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.
