Abstract

The article describes the methods of forming switching patterns of a three-level inverter with space-vector pulse-width modulation (PWM). Patterns are a combination of switching of the three nearest vectors from their set represented in the form of a well-known hexagon of basic vectors. The formation of the reference vector involving three basic vectors is known in the literature as NTV (Nearest Three Vectors). Depending on the magnitude of the modulation index taking values from 0 to 1, there are three different ranges. The aim of the research of this article is to optimize switching patterns in all ranges in order to reduce the number of commutation of inverter switches of high-power electric drives. The analysis of the inverter output voltage harmonics is given for different values of the modulation index and an optimized switching algorithm. It is noted that the optimized vector PWM algorithms with a reduced number of switching makes it possible to reduce switching losses and preserve the acceptable harmonic composition of the inverter output voltage. The results of the study were obtained on the basis of simulation modeling in the Matlab Simulink environment.
