“…In this scheme, we use many phases in the machine, each fed by a separate single phase PWM inverter, thus consisting a modular system where for each phase fault we isolate the module. If each module has minimum electrical, magnetic and thermal interaction, the system can continue operating without the faulted phase [6].…”

“…Using special design techniques, brushless permanent magnet (PM) motors can be made fault tolerant [2][3][4]. A comparative study carried out in [5] has suggested that both SRM and brushless PM motors have a similar degree of fault tolerance, while the brushless PM motor drives have a higher torque density and lower acoustic noise than SRM drives. In addition, in order to provide redundancy, a dual fault-tolerant brushless PM motor drive system was proposed in [6].…”

Fault-tolerant motor drives are becoming more important in safety critical applications. Using a special motor design and an appropriate inverter topology, brushless permanent magnet AC motor drives can have a fault-tolerant capability. This paper considers a dual motor drive system on a common shaft to introduce redundancy. The paper provides a systematic classification for the potential electrical faults which may occur in a real motor drive. In the paper, the switch and winding short circuit fault detection and identification methods are studied and experimental results are presented. In addition, the effects of switch faults on the phase currents and output torque are discussed, and remedial strategies for these faults are proposed. Furthermore, it was also demonstrated using simulation results that the proposed remedial strategies can compensate for the loss of torque due to the switch faults and can keep the peak-to-peak torque ripple factor comparable to healthy operation of the drive.

This paper presents the modelling and control of a multiphase AC-DC power conversion system. The mathematical model of a system comprising of multiple Permanent Magnet Generators (PMGs) and active rectifier systems is developed. The control objectives of DC link voltage stabilization, minimized reactive power transfer and dynamic load sharing issues are addressed. The system transient load sharing is achieved by matching the controller gain values with the load sharing requirements. Methods of steady state load sharing viz. automatic master slave control and droop based load sharing are developed for the application of parallel PMG and rectifier systems. A droop regulation scheme for DC link voltage control is proposed. The properties of each method are discussed. Simulation results are presented for a system with five fault tolerant multiphase PMG fed active rectifier units. The system is subjected to a severe loading step demand and the DC link voltage and the load sharing characteristics are analysed.
