چکیده
In this paper, a four-phase 8/10-pole dual armature-winding variable flux reluctance generator (DAW-VFRG) with double-redundant rectifier circuit is proposed for onboard generator. The integrating VFRG and armature winding structure improves fault-tolerant capability power density. Based on the airgap field harmonics analysis function theory, no-load back-EMF model inductance are deduced determining optimal stator/rotor pole combination. addition, based magnetic energy comparison, influence of connection categories between two sets windings circuits output also investigated when saturation effect considered. key design parameters globally optimized to improve simultaneously. Moreover, electromagnetic performance DAW-VFRG under both normal fault condition evaluated compared single half bridge rectifier. Finally, prototypes manufactured tested validate finite-element predictions.

متن کاملFault Diagnosis and Fault-Tolerant SVPWM Technique of Six-phase Converter under Open-Switch Fault
In this paper, a new open-switch fault diagnosis method is proposed for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The open-switch faults are detected without any additional equipment and complicated calculations, since the proposed fault detection method is integrated with the controller required ...

In this paper, the circulating current analysis between strands is studied while considering the different transpositions in the active part and without considering the transposition in the end winding region. First, this analysis is done while only considering the slot region, and then the end winding region is added to the model. The model used for this analysis is a circuit model, including ...
