“…While by and large postfault operating strategies require software reconfiguration only, meaning that the faulty phase(s) is not supplied any more, control algorithm modification (software reconfiguration), can be combined with hardware reconfiguration if the reason for the loss of supply to a phase is not a fault within the machine itself [131]. For example, in the case of a fault of one inverter leg in a six-phase motor drive, the phase that would be left without supply in postfault operation if only software reconfiguration were applied gets connected to one of the remaining healthy inverter legs (so that two motor phases are now supplied form the same inverter leg) using additional semiconductors (triacs) for this reconfiguration [131].…”

Although the concept of variable-speed drives, based on utilization of multiphase (n > 3) machines, dates back to the late 1960s, it was not until the mid-to late 1990s that multiphase drives became serious contenders for various applications. These include electric ship propulsion, locomotive traction, electric and hybrid electric vehicles, "more-electric" aircraft, and high-power industrial applications. As a consequence, there has been a substantial increase in the interest for such drive systems worldwide, resulting in a huge volume of work published during the last ten years. An attempt is made in this paper to provide a brief review of the current state of the art in the area. After addressing the reasons for potential use of multiphase rather than three-phase drives and the available approaches to multiphase machine designs, various control schemes are surveyed. This is followed by a discussion of the multiphase voltage source inverter control. Various possibilities for the use of additional degrees of freedom that exist in multiphase machines are further elaborated. Finally, multiphase machine applications in electric energy generation are addressed.Index Terms-Multiphase electric machines, multiphase variable-speed drives, multiphase voltage-source inverters (VSIs).

“…software re-configuration), so that in post-fault operation one or more phases of a multiphase machine are not supplied from the inverter any more. A rather different approach, in which a hardware re-configuration takes place, is described in [111] for an asymmetrical six-phase induction machine. In the case of a fault of one inverter leg, the phase that would be left without supply in post-fault operation if software re-configuration is applied gets connected to one of the remaining healthy inverter legs (so that two motor phases are now supplied form the same inverter leg) using additional semiconductors (triacs) for this re-configuration.…”

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.
