The invention provides a power supply circuit of a motor controller and a vehicle, and belongs to the technical field of electric vehicles. The power supply circuit of the motor controller comprises a power supply; the first power supply branch comprises a control switch, the control switch is connected in series between the power supply and the high-voltage side power supply end of the motor controller, and when the control switch is closed, the power supply supplies power to the high-voltage side power supply end of the motor controller; and the second power supply branch comprises an isolation device, the isolation device is connected in series between the control switch and the low-voltage side power supply end of the motor controller, and when the control switch and the isolation device are closed at the same time, the power supply supplies power to the low-voltage side power supply end of the motor controller. According to the power supply circuit of the motor controller and the vehicle, the power supply framework of the whole vehicle can be optimized, and the safety performance of the vehicle is improved.
