In accordance with the theory of vector space decomposition, the basic six-dimensional space (as, bs, cs, xs, ys, zs) of a dual-three phase induction machine with isolated neutral points can be transformed into two orthogonal two-dimensional subspaces (sa, sb) and (m1, m2) [8].…”

“…1 presents basic topology of dual three-phase drive system with two isolated neutral points [9]. To provide increased efficiency of the sixphase drives fed by power electronic converters, novel spacevector-based control and modulation strategies have been proposed and developed for both asymmetrical [6]- [10] and symmetrical [11]- [13] systems. It is necessary to mention, that asymmetrical and symmetrical six-phase drives have close efficiency in both static and dynamic control modes [13].…”

Novel methodology of synchronized pulsewidth modulation (PWM) has been disseminated for control of symmetrical six-phase (dual three-phase) induction motor drives fed by two three-phase inverters with single DC voltage source. Control algorithms are based in this case on the 60 0 -phaseshifting of control signals of two standard voltage source inverters. Four basic schemes of synchronized continuous and discontinuous PWM, applied for control of symmetrical dual three-phase systems, have been analyzed and compared. All these schemes allow providing cancellation of undesirable commonmode voltages in systems during the whole control range. Simulations give the behavior of symmetrical dual three-phase system with synchronized PWM. The spectra of the phase voltage of six-phase drives with algorithms of synchronized PWM do not contain even harmonics and sub-harmonics, which is especially important for the high power/high current applications.

The area of multiphase variable-speed motor drives in general and multiphase induction motor drives in particular has experienced a substantial growth since the beginning of this century. Research has been conducted worldwide and numerous interesting developments have been reported in the literature. An attempt is made to provide a detailed overview of the current state-of-the-art in this area. The elaborated aspects include advantages of multiphase induction machines, modelling of multiphase induction machines, basic vector control and direct torque control schemes and PWM control of multiphase voltage source inverters. The authors also provide a detailed survey of the control strategies for five-phase and asymmetrical six-phase induction motor drives, as well as an overview of the approaches to the design of fault tolerant strategies for post-fault drive operation, and a discussion of multiphase multi-motor drives with single inverter supply. Experimental results, collected from various multiphase induction motor drive laboratory rigs, are also included to facilitate the understanding of the drive operation.
