“…Indeed, one of the first actual applications of a multiphase electric drive was aimed at such an application [218] and it was based on utilization of an asymmetrical six-phase synchronous motor. Highpower multiphase synchronous motors for such applications are usually supplied from current-source thyristor-based 12-pulse LCIs [219], [220]. Typically, two three-phase windings are displaced by 30 • and supplied by two independent threephase LCIs, which receive dc current from two three-phase rectifiers [219].…”

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).

Some high-torque electric machines, such as lowspeed wind generators, may be very difficult to test on load because of the large and expensive mechanical equipment required to load them (motors) or to drive them (generators). In this paper, a full-load regenerative testing methodology is described which does not require any rotating equipment to be coupled to the machine where the rated active power flows in a closed loop between the machine and a suitably connected dual-stage converter. The successful application of this methodology to a 780-kW 14-r/min wind generator prototype is addressed as a study case. Relevant experimental results are reported in a companion paper.

This paper investigates a back to back test simulation of an interior permanent magnet (IPM) synchronous machine with fractional slot concentrated windings (FSCW). The studied machine is designed to equip a floating vertical axis wind turbine. The principal characteristics and the structure of the machine are presented, as well as the back to back test principle. The parking brake mode is investigated to determine at which aerodynamic torque the system converters have to be started. The designed system and the simulations results, obtained with the Matlab-Simulink platform are described. Simulation results obtained with the proposed control are compared to those obtained with the equivalent single-phase diagram.Keywords-Back to back (BTB) test; fractional slot concentrated winding (FSCW); interior permanent magnet (IPM) machine; parking brake mode; voltage oriented control (VOC); wind turbine.
