摘　　要：本文分析了弧焊电源的传导骚扰的产生机理,介绍了传导骚扰测试标准及测试方法,通过对几种样机的传导骚扰测试表明,虽然添加合适的滤波器可以使传导骚扰低于标准的限值,但在焊接设计之初就采取软开关功率变换技术并对可能产生传导骚扰的部件采取滤波、屏蔽等措施,可有效降低传导型电磁发射的水平,容易符合传导骚扰的限值要求并留有较大的裕量。this paper presented the reason and measurement standard of conducted interference on arc welding inverter power, and compared the common arc welding inverter power with ones adopting restrain measures by conducted interference measurement,the result validated the feasibility of restrain measures. This paper has great guiding meanings for EMC design on arc welding inverter power.
