A new space-vector-based sigma delta modulation scheme for any general N-level voltage source inverter is proposed in this paper, which directly quantizes the reference space vector. The proposed scheme uses the sigma delta modulation with the quantizer implemented by the proposed space vector quantizer. A new scheme is proposed for directly quantizing

Modules are a generalization of the vector spaces of linear algebra in which the “scalars” are allowed to be from an arbitrary ring, rather than a field. This rather modest weakening of the axioms is quite far reaching, including, for example, the theory of rings and ideals and the theory of abelian groups as special cases.

The theory of vector spaces—also referred to as linear algebra—is as important and widespread in higher mathematics as calculus. Most notably, it provides a complete understanding of the solvability of systems of linear equations. For our purposes, we will need no more than the basic features of the theory.

CORDIC Implementation of Space Vector Modulation
2008 IEEE Industry Applications Society Annual Meeting, 2008Space vector modulation (SVM) is commonly used in motor drives. In order to reduce the calculation time in SVM a coordinate rotation digital computer (CORDIC) algorithm is used to generate trigonometric functions. The algorithm is implemented using a microcontroller.

Inverter Control with Space Vector Modulation
2008Figure 2.1 shows the principle circuit of an inverter fed 3-phase AC motor with three phase windings u, v and w. The three phase voltages are applied by three pairs of semiconductor switches v u+/v u−, v v+/v v- and v w+/v w− with amplitude, frequency and phase angle defined by microcontroller calculated pulse patterns.

This article outlines the theoretical principles and practical implementation of Space Vector Modulation (SVM) for two-level and three-level inverters. As a highly efficient alternative to traditional carrier-based modulation, SVM operates in the stationary Clarke reference frame.

The space vector (SVM) modulation, also known as SVPWM, is increasingly replacing more traditional modulations such as six-step and sinusoidal modulation as it provides better use of the available DC-link voltage and a reduction in harmonic content.

An effective software implementation of the space-vector modulation
IEEE Transactions on Industrial Electronics, 1999An effective software implementation of the space-vector modulation (SVM) on the rotating - frame is proposed. The conven- tional SVM algorithm requires complex computations, such as square root and arctangent. The SVM algorithm is further developed to deter- mine directly conduction times of switches without requiring complex computations.
