A　novel　neutral　point　(NP)　voltage　control　strategy　of　three-level　neutral　point　clamped　(NPC)　converter　was　proposed　to　eliminate　the　NP　voltage　fluctuation　under　any　modulation　strategy.　The　novel　NP　voltage　control　strategy　was　based　on　the　control　target　of　output　line　voltage,　and　real-time　correction　of　output　switching　states　were　given　according　to　the　NP　voltage　fluctuation.　It　is　suitable　for　any　modulation　strategy　as　it　only　deals　with　the　output　switching　states　of　any　modulation　strategy.　In　order　to　analyze　the　control　effect　of　the　proposed　strategy,　the　single　switch　cycle　control　region　was　taken　as　the　measurement　standard　and　analysis　of　fully　control　region　was　conducted　respectively　when　using　the　two　most　commonly　used　modulation　strategy,　sinusoidal　pulse　width　modulation　(SPWM)　strategy　and　space　vector　pulse　width　modulation　(SVPWM).　The　theoretical　analysis　and　simulation　results　show　that　the　novel　NP　voltage　control　strategy　has　the　advantages　of　wide　application　and　easy　implementation.　Whereas,　the　fully　control　region　of　the　new　strategy　is　affected　by　modulation　strategy,　modulation　index　and　power　factor.　©,　2014,　Editorial　Department　of　Electric　Machines　and　Control.　All　right　reserved.
