Abstract：

This　paper　focuses　on　finding　a　novel　strategy　for　reconstructing　induction　motor　phase　currents　from　the　DC-link　current　of　two-level　voltage　source　inverters.　The　main　problems　are　presented　and　different　PWM　techniques　include　SVPWM,　NSPWM,　AZSPWM　and　RPWM(RPP)　are　compared　in　this　paper　are　discussed.　RPP　strategy　is　proved　that　it　can　be　effectively　reduce　the　invalid　regions　both　around　zero　voltage　and　near　active-vectors　and　suite　for　proposed　use.　And　the　influence　of　the　EMI　during　reconstructing　phase　current　also　mentioned　in　this　paper.　Experiment　result　confirms　the　validity　of　the　new　method.　©　2010　IEEE.
