PROBLEM TO BE SOLVED: To provide a power supply control system capable of executing discharge while adjusting so that a surge voltage becomes smaller than a voltage resistance of an inverter when an input voltage into the inverter exceeds a threshold value.SOLUTION: The power supply control system includes: an inverter which can invert a DC current supplied from a DC power supply and supply the AC current to a motor as a driving current for driving the motor; a converter which can adjust the DC current supplied from the DC power supply and supply the DC current to the inverter; a capacitor disposed between the inverter and the converter; and a control part which can control the inverter and the converter. The control part includes an adjustment instruction part which can, after stopping the converter when the input voltage into the inverter is in excess of the threshold value, can make the motor discharge the input voltage by making the inverter adjust the driving current so that a surge voltage becomes a smaller voltage than the voltage resistance of the inverter.SELECTED DRAWING: Figure 1 |
