This　study　proposes　a　simplified　space　vector　pulse-width　modulation　(SVPWM)　method　for　multilevel　converters.　To　avoid　unnecessary　coordination　transformations,　firstly,　a　further　derivation　is　conducted　on　the　basis　of　the　60　degrees　coordinate　transformation.　Then,　all　the　nearest　three　vectors　(NTVs),　duty　cycles　and　optimal　switching　sequence　within　one　switching　period　can　be　identified　through　a　simple　comparison　of　three-phase　modulation　waves.　To　further　reduce　the　switching　frequency,　detailed　steps　to　achieve　the　minimum　number　of　transitions　among　different　NTVs　are　constructed.　Combined　with　the　optimal　switching　sequence　within　one　switching　period,　the　minimum　number　of　transitions　within　a　fundamental　period　can　be　achieved　easily.　Finally,　a　thorough　discussion　is　conducted　to　simplify　the　procedure　further　and　the　flowchart　for　the　proposed　SVPWM　is　also　presented.　Compared　with　the　previous　methods,　the　proposed　method　does　not　require　any　iterative　calculation　or　coordinate　transformation.　To　the　best　of　the　authors＇　knowledge,　the　calculation　amount　is　reduced　by　almost　seven　times　compared　with　the　methods　proposed.　In　addition,　the　switching　frequency　and　total　harmonic　distortions　remain　at　the　same　level　without　any　deterioration.　Finally,　the　simulation　and　experiment　for　modular　multilevel　converter　are　performed　to　verify　the　correctness　and　efficiency　of　the　proposed　method.
