摘要：

A　three-phase　welding　inverter　power　supply　(WIPS)　with　power　factor　correction　(PFC)　function　is　proposed　to　deal　with　the　input　currents　distortion　problem　that　baffled　WIPS　application　for　several　years.　In　this　paper,　a　switch-rectifier　is　used　and　controlled　by　a　digital　signal　processor　(DSP)　based　on　space　vector　modulation　(SVM)　to　replace　diode-rectifier　of　the　conventional　WIPS.　The　control　strategy　to　realize　PFC　function　in　WIPS　is　studied.　A　new　two-mode　work　scheme　is　proposed　to　overcome　the　problems　brought　by　switch-rectifier　when　WIPS　work　in　open-load　period.　A　new　WIPS　device　with　PFC　function　is　constructed　and　experimented　to　confirm　the　validity.　©　2003　IEEE.
