The invention provides an all-in-one vehicle-mounted power supply device, a motor controller and a power assembly. Power control circuits of a compressor and a heater are integrated to save hardware cost. The vehicle-mounted power supply device comprises a shell, and a power conversion circuit, a switch module and a compressor motor driving circuit which are accommodated in the shell. And a compressor motor interface and a heating module interface are arranged on the surface of the shell. The power conversion circuit is used for receiving alternating current and outputting first direct current to charge the power battery or supply power to the compressor motor driving circuit. The compressor motor driving circuit comprises three bridge arms which are connected in parallel, the two ends of the three bridge arms are used for receiving first direct current or receiving power supplied by a power battery, and the middle point of each bridge arm is used for being connected with a phase winding of a compressor motor through a compressor motor interface. Wherein the bridge arm midpoint of the at least one bridge arm is used for driving the heating module through the heating module interface, and the switch module is used for connecting or disconnecting the bridge arm midpoint of the at least one bridge arm and the heating module.

    本申请提供了一种多合一的车载供电装置、电机控制器及动力总成,融合压缩机和加热器的功率控制电路以节省硬件成本。车载供电装置包括壳体、容纳于壳体内的功率变换电路、开关模块和压缩机电机驱动电路。壳体的表面设置有压缩机电机接口和加热模块接口。功率变换电路用于接收交流电并输出第一直流电为动力电池充电或为压缩机电机驱动电路供电。压缩机电机驱动电路包括相并联的三个桥臂,三个桥臂的两端用于接收第一直流电或接收动力电池供电,每个桥臂的桥臂中点用于通过压缩机电机接口连接压缩机电机的一相绕组,其中至少一个桥臂的桥臂中点用于通过加热模块接口驱动加热模块,开关模块用于导通或断开至少一个桥臂的桥臂中点和加热模块的连接。
