Abstract：

IGBT　arc　welding　power　source　will　generate　serious　EMI.　Experientially,　filtering,　shielding　and　grounding　are　three　important　ways　to　reduce　EMI.　Compare　tests　were　taken　to　analysis　the　suppression　methods　according　to　CISPR　11,　which　specified　provisions　for　the　test　site　measurements　and　limits　of　electromagnetic　disturbances.　And　compare　conducted　emission　and　radiated　emission　for　both　the　soft-switching　welder　and　hard-switched　welder　under　same　working　conditions.　It　found　that　choosing　appropriate　topological　structure　and　component　parameter　of　filter　can　effectively　suppress　the　conducted　emission.　And　the　EMI　suppression　effect　is　not　ideal　when　using　soft-switching　technology.
