The invention provides a motor controller, a high-voltage distribution box, a power assembly and an electric vehicle, and relates to the technical field of power electronics. The motor controller comprises an inverter circuit, an alternating current charging circuit and a controller. The inverter circuit converts direct current provided by the power battery pack into alternating current and then provides the alternating current for the six-phase motor. The first input end and the second input end of the alternating current charging circuit are used for being externally connected with an alternating current power supply, and the first output end of the alternating current charging circuit is connected with the input end of one phase winding in the first three-phase winding or connected with a center tap of the first three-phase winding; and the second output end of the alternating current charging circuit is connected with the input end of one phase winding in the second three-phase winding, or is connected with the center tap of the second three-phase winding. The controller is used for controlling the inverter circuit so that the alternating current power supply can charge the power battery pack. By means of the scheme, OBC arrangement is avoided, and therefore cost is reduced, and the electric drive system can be evolved towards the miniaturization and high integration level direction conveniently.

    本申请提供了一种电机控制器、高压配电盒、动力总成及电动车辆,涉及电力电子技术领域。电机控制器包括逆变电路、交流充电电路和控制器。逆变电路将动力电池组提供的直流电转换为交流电后提供给六相电机。交流充电电路的第一输入端和第二输入端用于外接交流电源,交流充电电路的第一输出端连接第一三相绕组中的一相绕组的输入端,或连接第一三相绕组的中心抽头;交流充电电路的第二输出端连接第二三相绕组中的一相绕组的输入端,或连接第二三相绕组的中心抽头。控制器用于控制逆变电路,以使交流电源对动力电池组充电。利用本方案,避免了布置OBC,因此降低了成本,也便于电驱动系统朝着小型化、高集成度方向进行演进。
