Title
Fault-Tolerant Performance of a Three-Phase Dual Armature-Winding Doubly Salient Brushless DC Generator.
Abstract
The fault-tolerant generator is widely adopted in high-reliability applications. This paper comprehensively investigates the fault-tolerant performance of a five-phase 20/16-pole single armature winding doubly salient brushless dc generator (SAW-DSBLDCG) and a three-phase 12/8-pole dual armature winding DSBLDCG (DAW-DSBLDCG). The two generators are connected to half wave rectifiers. The configurations, the principles, and the characteristics of fault-tolerance for two generators are analyzed. Comparisons in terms of the no-load and load characteristics of three-phase DAW-DSBLDCG with normal and open-circuit faults, the output voltages, powers, and magnetic flux density distributions of the two generators are conducted using finite element method, and the armature reaction characteristics under fault conditions are analyzed. The results show that the three-phase DAW-DSBLDCG has higher power density than the five-phase SAW-DSBLDCG under normal and fault conditions. A prototype three-phase 12/8-pole DAW-DSBLDCG is developed, and the simulation and experimental results show that the three-phase DAW-DSBLDCG with hybrid half-wave rectifier structure has high fault-tolerance ability.
