Multi-phase inverter Space Vector Modulation
2013 IEEE 7th International Power Engineering and Optimization Conference (PEOCO), 2013This paper presents the comparison between two switching techniques for a multi-phase voltage source inverter (VSI) using Space Vector Modulation (SVPWM). Two different techniques which based on large vectors and the combination of large and medium vectors have been examined under a two-level five-phase inverter. The performance of these techniques are

Direct Space Vector Modulated Matrix Converter
SSRN Electronic Journal, 2018Matrix converter has emerged as a best substitution of the conventional converters due to the capability of power regeneration, the sinusoidal input and output waveforms, and no need for energy storage. MC is a single - stage converter having sinusoidal input as well as output voltage and current.

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.

Modules at last! In most books on a similar subject modules appear on the very first pages. And there are good reasons for this. Ring theory and module theory are symbiotic. Many questions about rings can be handled most effectively by using modules. Moreover, sometimes modules seem to be inevitable.

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.

Duality, Vector Spaces and Absolutely Convex Modules
Applied Categorical Structures, 2006An interpretation of absolutely convex modules subject to a separatedness condition as the numerical counterpart of vector spaces is given. It is shown that the full reflective embedding \({\mathcal V}ec \to {\mathcal{AC}}\) is at the same time coreflective, too.

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.

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 ...

Let K be a field. A vector space V over the field K is an additive (abelian) group, together with a multiplication of elements of V by elements of K, i.e. an association $$ \left( {x,v} \right) \mapsto xv $$ of K × V into V, satisfying the following conditions: VS 1. If 1 is the unit element of K, then 1 υ = υ for all υ ∈ V. VS 2.
