Hye-Ung Shin and Kyo-Beum Lee, "Fault-Tolerant Switched Reluctance Machine Drives Using a Current Park's Vector," in Proc. CENCON Conf., Oct. 2015, pp. 19–24. > Paper

This paper presents a new fault-tolerant technique, on the basis of the current Park's vector, which is applied to switched reluctance

machine (SRM) drives. Open- and short-fault occur in the power converter switches. A proposed current Park's vector can diagnose

these faults. In addition, A position of the short-fault in the asymmetric bridge converter can be detected using the proposed another

method. The fault-tolerant controls are performed after a fault diagnosis. An open-fault tolerant control can perform considering the

adjacent phase switches. A short-fault tolerant control can perform using remaining switch of fault phase. These fault occurrences

can be identified in the affected motor phase. A simulation is performed with a four-phase SRM drive system, and the results are ​

presented to verify the validity of the proposed method.
