摘　　要：提出了一种基于半控变流器(HCC)馈电及电流协调控制的双三相永磁同步发电机(PMSG)系统机侧变流器容错运行策略,该策略可实现双三相PMSG变流器开关故障时的运行状态切换并保证系统正常运行。在一台1 kW的实验样机上对所提出的控制策略进行实验验证,结果证明了该变流器容错策略的可行性和有效性。A converter fault-tolerant strategy based on half-controlled converter（HCC） and complementary current control for dual three-phase permanent magnet synchronous generator（PMSG） system is proposed.The proposed control strate- gy is aimed at realizing the operation mode switching when one IGBT of the converter works abnormally.Experimental tests based on a 1 kW prototype validate that the proposed fault-tolerant control strategy for generator side converter in dual three-phase PMSG is available and effective.
