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 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.

A Novel Space-Vector Modulation Method for Nine-Switch Converter
IEEE transactions on power electronics, 2020Nine-switch converter (NSC) has been presented as a dual-output converter with common frequency (CF) or different frequency (DF) operation modes. This paper proposes a novel space-vector modulation (SVM) method for the NSC that supports both the CF and ...

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.

Space Vector Modulated Matrix Type Rectifier
2019 IEEE International Conference on Sustainable Energy Technologies and Systems (ICSETS), 2019In this paper, space vector modulated isolated matrix type three phase AC/DC converter has been investigated. The topology is derived from matrix rectifier by adding a high frequency transformer. Space vector pulse width modulation (SVPWM) is the most commonly used modulation method for matrix rectifier.

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

Optimal Space Vector Modulation of Current-Source Converter for DC-Link Current Ripple Reduction
IEEE transactions on industrial electronics (1982. Print), 2019DC-link current ripple is one of the important factors for operating the current-source converter. In practice, the dc-link current ripple can be reduced by increasing the switching frequency or inductance.
