Abstract
A power supply control device includes an inverter having plural switching elements, an inverter controller that controls the inverter, a device power supply that generates a first power supplied to the inverter controller, a detector that detects whether there is an abnormality relating to the compressor, and a power supply controller. The inverter generates drive voltages usable to drive a compressor motor that is a drive source of a compressor as a result of the switching elements switching on or off, and outputs the drive voltages to the compressor motor. The power supply controller stops generation of the first power by the device power supply to thereby stop the control of the inverter controller in a case where there is an abnormality relating to the compressor.
