摘要
在功率管发生开路故障时,为了使开关磁阻电机(switched reluctance motor,SRM)功率变换器的电机可继续保持正常功率,基于Maxwell+Simplorer环境,分析了功率变换器主要故障对电机性能的影响,并以不对称半桥型功率变换器为基础,针对功率开关管开路故障,提出了一种容错型功率变换器,即用不相邻正常相桥臂上的器件代替故障器件,有效地隔离了故障元件.结果表明:该功率变换器具有良好的容错性能,能够使电机在故障后继续正常运行.
To make the power converter of switched reluctance motor （SRM） continue to maintain the normal power when the open-circuit failure occurs, the effects of main faults of the power converter on motor＇s performances were analyzed in the environment of Maxwell ＋ Simplorer and a fault tolerant power converter based on asymmetric half-bridge power converter was presented, which can make the device with non-adjacent normal phase bridge instead of faulty devices and effectively isolate the faulty devices. Results show that the power converter has good fault-tolerant performance and can enable the motor to operate normally after failure.
