COMPRESSOR CONTROL DEVICE, POWER FACTOR IMPROVEMENT CIRCUIT, HEAT RADIATION STRUCTURE FOR ELECTRICAL COMPONENT, AND ELECTRICAL EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a compressor control device that can prevent a compressor etc., from abnormally heating up or breaking owing to a step-out of the compressor without detecting the step-out of the compressor through software, and can use a general compressor.SOLUTION: A compressor control device includes: an inverter part which converts a DC voltage into a three-phase AC voltage and supplies the AC voltage to a three-phase AC motor; a compressor which is driven by the three-phase AC motor; a first heat-sensitive switch which turns on at a first predetermined temperature; and a second heat-sensitive switch which turns on at a second predetermined temperature. A first output terminal of the inverter part and the compressor are connected to each other through the first heat-sensitive switch. A second output terminal of the inverter part and the compressor are connected to each other through the second heat-sensitive switch. The first heat-sensitive switch and second heat-sensitive switch are provided on an exterior surface of the compressor.
