The vast majority of electric power generation systems, products and industrial processes use machines with a number of phases equal to three. The predominance of the three-phase system led to the more frequent use of three-phase machines. However, with the advancement of the semiconductor switches and the development of converters, the number of phases is no longer a limiting factor in the study and application of polyphase machines. It is possible to use machines with a number of phases higher than three and to obtain several advantages, such as: lower sensitivity to voltage unbalance, reduction of ripple frequency, reduction of bus voltage when associated to multilevel converters, reduction of current harmonics in the DC bus, increase of...
