“…Compared with conventional three-phase machines, multiphase machines with sinusoidal spatial magnetomotive force distribution have lower space harmonics, greater fault tolerance, lower pulsating torque, and lower per phase power ratings for given power [1][2][3][4]. Multiphase generators have been studied much less than multiphase variable-speed drives and this remains to be an interesting topic, especially for WECS.…”

“…Multiphase drives do not need extra electrical equipment to manage post-fault operation, requiring only proper postfault control techniques in order to continue operating [2]. Therefore, they are ideal for traction and aerospace applications for security reasons or in offshore wind farms where corrective maintenance can be difficult under bad weather conditions [3][4][5][6].…”

Multiphase machines have been recognized in the last few years like an attractive alternative to conventional three-phase ones. This is due to their usefulness in a niche of applications where the reduction in the total power per phase and, mainly, the high overall system reliability and the ability of using the multiphase machine in faulty conditions are required. Electric vehicle and railway traction, all-electric ships, more-electric aircraft or wind power generation systems are examples of up-to-date real applications using multiphase machines, most of them taking advantage of the ability of continuing the operation in faulty conditions. Between the available multiphase machines, symmetrical five-phase induction machines are probably one of the most frequently considered multiphase machines in recent research. However, other multiphase machines have also been used in the last few years due to the development of more powerful microprocessors. This chapter analyzes the behavior of generic n-phase machines (being n any odd number higher than 3) in faulty operation (considering the most common faulty operation, i.e. the openphase fault). The obtained results will be then particularized to the 5-phase case, where some simulation and experimental results will be presented to show the behavior of the entire system in healthy and faulty conditions. The chapter will be organized as follows:First, the different faults in a multiphase machine are analyzed. Fault conditions are detailed and explained, and the interest of a multiphase machine in the management of faults is stated. The effect of the open-phase fault operation in the machine model is then studied. A generic n-phase machine is considered, being n any odd number greater than three. The analysis is afterwards particularized to the 5-phase machine, where the openphase fault condition is managed using different control methods and the obtained results are compared. Finally, the conclusions are presented in the last section of the chapter.

“…Nevertheless, regenerative braking requires bidirectional power flow, which is typically achieved using active front-end rectifiers and a back-to-back arrangement of voltage source converters (VSCs). Even though this topology is commonly used in high-power applications (traction and wind energy systems [2][3][4][5], to name a few), in many induction motor drives the use of diode front-end rectifiers is preferred due to the lower cost and improved reliability [6]. In such a case, the braking power cannot be delivered to the grid and needs to be absorbed somewhere.…”

Abstract-Induction motor drives supplied from diode front-end rectifiers are commonly used in industrial applications due to their low cost and reliability. However, the two-quadrant operation of such a topology makes the regenerative braking impossible. Braking resistors can be used to dissipate the braking power and provide enhanced braking capability, but additional hardware is then necessary. Alternatively, the braking power can be dissipated within the inverter/motor by control software reconfiguration. In this scenario, the additional degrees of freedom of multiphase drives can be used to increase the system losses without disturbing the flux and torque production. Experimental results confirm the possibility to enhance the braking capability of six-phase drives with only few changes in the control scheme.Index Terms-Multiphase induction motor drives, braking methods, field oriented control.
