This application discloses a hybrid-power-component motor control unit and a power system, where the motor control unit and the power system are applied to the field of electric vehicle technologies. A type of a power component in a first drive circuit of the motor control unit is different from a type of a power component in a second drive circuit of the motor control unit. A loss of the power component in the first drive circuit is greater than a loss of the power component in the second drive circuit. A current withstand capability of the power component in the first drive circuit is greater than a current withstand capability of the power component in the second drive circuit. The first drive circuit inverts a direct current into an alternating current, and supplies the alternating current to a first part of windings of the motor. The second drive circuit inverts a direct current into an alternating current, and supplies the alternating current to a second part of windings of the motor. When determining that a load of the motor is less than a preset load, the control unit controls the first drive circuit to stop working and controls the second drive circuit to work. When determining that the load of the motor is greater than or equal to the preset load, the control unit controls both the first drive circuit and the second drive circuit to work. According to the motor control unit, efficiency of the motor control unit can be effectively improved.
