The utility model provides a power supply control circuit and a power supply system. The power supply control circuit comprises an on-off module, a detection module and a control module, the on-off module is arranged between the input side and the output side of the power supply and is used for controlling on/off between the input side and the output side; the detection module is connected between the on-off module and the output side and is used for acquiring a first voltage output to the output side by the on-off module; the control module is connected with the on-off module and the detection module, and the control module is used for outputting a first control signal according to the voltage value of the first voltage so as to control on/off of the on-off module; on one hand, the first voltage output by the on-off module is detected, so that the capability of monitoring the output voltage of the power supply is improved; on the other hand, the control module is arranged to adjust the duty ratio of the firs
