Abstract
A vehicle-mounted power supply system includes a sampling circuit, a voltage comparison control circuit, a power conversion circuit, and a motor. The sampling circuit is configured to obtain an output voltage value of an output terminal of the power conversion circuit. The voltage comparison control circuit is configured to output a first power adjustment signal to the power conversion circuit when the output voltage value is less than a first target voltage value. The power conversion circuit is configured to increase an output voltage to a first target voltage based on the first power adjustment signal, to output the output voltage to the motor and increase an input voltage of the motor. When a voltage of a power supply is low, the input voltage of the motor can be maintained at a required level.
