IEEE Transactions on Industrial Electronics, 2002 This paper comprehensively analyzes the relationship between space-vector modulation and three-phase carrier-based pulse width modulation (PWM). The relationships involved, such as the relationship between modulation signals (including zero-sequence ...

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.

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.

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.

Space-Vector Modulated Multilevel Matrix Converter
IEEE Transactions on Industrial Electronics, 2010A matrix converter is an ac-ac power converter topology that has received extensive research attention as an alternative to traditional ac-dc-ac converter. A matrix converter is able to convert energy from an ac source to an ac load without the need of a bulky and limited-lifetime energy-storage elements.

Space-time vector delta-sigma modulation
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003Classical delta-sigma modulation gains resolution through temporal oversampling by using a high-speed, low-resolution quantizer and shaping the resulting quantization errors out of the signal band. Likewise, spatial delta-sigma modulation is often used in image halftoning to create high-visual-quality binary images.

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.

ON MODULATED TOPOLOGICAL VECTOR SPACES AND APPLICATIONS
Bulletin of the Australian Mathematical Society, 2019We introduce a notion of modulated topological vector spaces, that generalises, among others, Banach and modular function spaces. As applications, we prove some results which extend Kirk’s and Browder’s fixed point theorems. The theory of modulated topological vector spaces provides a very minimalist framework, where powerful fixed point theorems are ...
