Review and classification of space-time vectors of discrete states ofa seven-phase converter

Abstract

The subject of the research is the control algorithms for aseven-phase converter that implement space-vector voltage modulation of aseven-phase motor as an alternative to a three-phase engine in modernelectric traction. The study used elements of set theory, combinatorics,Fourier series expansion and vector analysis. Checking research results wasimplemented on a special stand for experimental studies of spatial vectorvoltage modulation of a seven-phase motor. Keywords: Power of the mathematical set of logical states of aseven-phase converter, vector space of generalized vectors of discretestate, combinations of generalized vectors of discrete voltage states of aseven-phase motor\
