The invention provides a motor controller, a distributed power assembly, a hybrid power assembly and a vehicle, the motor controller is used for receiving power supplied by one of two battery modules of a power battery pack and outputting three-phase alternating current to a driving motor, and the motor controller comprises two direct current input ends, one direct-current input end is used for being connected with the positive electrode of one battery module, and the other direct-current input end is used for being connected with the negative electrode of one battery module; one end of the three-phase bridge arm is used for being connected with one direct current input end through a positive direct current bus, and the other end of the three-phase bridge arm is used for being connected with the other direct current input end through a negative direct current bus; and the protection device is used for disconnecting the connection between one direct current input end and one end of the three-phase bridge arm and/or the connection between the other direct current input end and the other end of the three-phase bridge arm when the motor controller fails. When the motor controller breaks down, the protection device is disconnected, so that the normal operation of other electric drivers can be prevented from being influenced by fault diffusion.
本申请提供了一种电机控制器、分布式动力总成、混合动力总成和车辆,该电机控制器用于接收动力电池组的两个电池模组中的一个电池模组供电并向驱动电机输出三相交流电,该电机控制器包括两个直流输入端,一个直流输入端用于连接该一个电池模组的正极,另一个直流输入端用于连接一个电池模组的负极;三相桥臂,三相桥臂的一端用于通过正直流母线连接一个直流输入端、另一端用于通过负直流母线连接另一个直流输入端;保护装置,用于在电机控制器故障时断开一个直流输入端和三相桥臂的一端之间的连接和/或另一个直流输入端和三相桥臂的另一端之间的连接。当电机控制器故障时,该保护装置断开,可以避免故障扩散而影响其他电驱的正常运行。
