POWER SUPPLY CONTROL DEVICE

摘要

To provide a power supply control device that reliably stops the operation of a compressor in a case where an abnormality has occurred in the compressor. A compressor inverter (28) has plural transistors (Q28a to Q28f), generates drive voltages (SU1 to SW1) for driving a compressor motor (M2) as a result of the transistors (Q28a to Q28f) switching on or off, and outputs the drive voltages (SU1 to SW1) to the compressor motor (M2). A compressor microcomputer (30) controls the compressor inverter (28). A switching power supply (24) generates first power (VI) supplied to the compressor microcomputer (30). In a case where there is an abnormality relating to the compressor, a power supply control switch (S25) stops the generation of the first power (V1) by the switching power supply (24) to thereby stop the control of the compressor microcomputer (30).
