Some new representations of the multilevel inverter voltage space vector in the complex plane

摘要

The paper proposes some new expressions in several coordinate systems (oblique-angled 60- and 120-degree coordinates, barycentric and affine coordinates on triangles) for the voltage space vector of the multilevel voltage source inverter. The offered space vector representations can be useful for the real time digital signal processor control of converters, some of them lead to the algorithmic simplifications.
