Ferramenta de automação de PWM Vetorial para sistemas multidimensionais.

Abstract

This work presents a tool for the automation of space-vector PWM technique in static converters, directly applied to multi-dimensional vector spaces. The strategy permits an automatic choice of a group of voltage space vectors destined to synthesize a given reference voltage vector. Based in numeric criteria, the tool elects a group of appropriate vectors. The tool can be applied in three-dimensional and four-dimensional systems. The steps for the implementation of the simulation algorithm and the strategies adopted for the reduction of the computational effort are mentioned as well. The effectiveness of the tool is proved by its application in two systems. The first one consists in a topology of a four-wire converter, represented by a three-dimensional space. The second one is a topology of a nine-leg converter, represented by a four-dimensional space. Both systems are described and the simulation results are presented and discussed.
