摘要 提出一种具有容错能力的最小开关逆变器,对采用该容错逆变器取代常规六开关逆变器的永磁同步电机(PMSM)直接转矩控制(DTC)系统进行了深入研究.当容错逆变器的开关器件发生故障或电机发生故障时,此逆变器可重构为2种四开关逆变器.进一步建立了四开关逆变器的模型,提出了针对故障隔离后四开关逆变器供电的PMSM系统的新型DTC策略.对正常及故障状态下容错逆变器供电的PMSM DTC系统进行了仿真研究和实验验证.结果表明,基于容错逆变器的PMSM系统在故障状态下采用新型逆变器拓扑结构以及新型DTC策略后,可持续稳定运行,并保持了良好的动态性能. A fault tolerant inverter with minimum-switch based permanent magnet synchronous motor (PMSM) direct torque control (DTC) drive system was investigated. The fault tolerant inverter, which was used to replace the standard 6-switch 3-phase inverter in the normal PMSM DTC drive system, can be reconfigured to two 4-switch inverters when inverter faults or motor faults occurred. Modelling of the post-fault 4-switch inverters was analyzed, and a modified DTC strategy based on these two post-fault 4- switch inverters was proposed for the disturbance-free operation of the PMSM drive. The proposed PMSM DTC system was simulated under both normal and faulty conditions, and simulation and experimental results verified that the modified PMSM DTC drive system can operate stably and continuously with acceptable steady state performance and excellent dynamic performance even under faults.
