弧焊逆变电源的谐波抑制
Humorous Wave Restrain of Arc Welding Electric Power Supply
【摘要】 针对弧焊逆变电源谐波产生的原因、特点及危害,介绍了无源滤波器、有源滤波器、软开关技术等抑制对策,以及三种谐波抑制措施特点。通过分析指出,传统的无源滤波方式存在不足,而有源滤波能弥补它的不足,另外,软开关技术的应用,在一定程度上也可以达到良好的滤波效果。
【Abstract】 It introduces restrain countermeasure of passive filter,active filter and soft switch technology,etc.and each restrain measure and feature of three humorous waves aim at the produced cause,feature and harm of humorous wave of arc weld electric power supply.It points out that traditional passive filter mode exist shortage and active filter can make up its shortage via analysis,in addition,the application of soft switch technology can also achieve all right filter effect to a certainty extent.
