摘要:This paper presents generalized space vector pulse width modulation (SVPWM) scheme for multilevelinverter. The SVPWM scheme generates all the available switching states and switching sequences based on twosimple and general mappings, thus independent of the level number of the inverter. The generalized method ofgenerating the switching states (first mapping), calculating duty cycles, and determining the switching sequence(second mapping) is described in this paper. The scheme is suitable for every reference vector with any modulationindex, and can be conveniently extended to meet specific requirements, such as symmetric switching sequences.Comparing with previous methods, the SVPWM scheme proposed in this paper provides two more degrees of freedom,i.e., the adjustable switching sequences and duty cycles, thus offering significant flexibility for optimizing theperformance of multilevel inverters. In this paper, open loop speed control of three phase induction motor using spacevector pulse width modulation is presented by using MATLAB/SIMULINK model.
