<p>The purpose of the invention is to provide a power supply control device that reliably stops the operation of a compressor when an abnormality occurs in the compressor. A compressor inverter (28) has a plurality of transistors (Q28a to Q28f) and turns on or off the transistors (Q28a to Q28f) to generate driving voltages (SU1 to SW1) for driving a compressor motor (M2) and output the driving voltages (SU1 to SW1) to the compressor motor (M2). A compressor microcomputer (30) controls the compressor inverter (28). A switching power supply unit (24) generates a first power supply (V1) supplied to the compressor microcomputer (30). When an abnormality occurs in a compressor, a power supply control switch (S25) stops the switching power supply unit (24) from generating the first power supply (V1), thereby stopping the control by the compressor microcomputer (30).</p> |
