A compressor control device, a method for controlling a compressor, and a refrigerator including the same are provided. The compressor control device controls the compressor to be driven using a mode in which the compressor is selectively driven by an inverter and a mode in which the compressor is driven directly using a supply voltage, according to a quality of the supply voltage, a loss which is caused by use of the inverter reduced or removed by directly providing the supply voltage to the compressor within a predetermined voltage or frequency range, and an increased energy efficiency by reducing power consumption.

Device and method for controlling compressor, and refrigerator including same

The present invention relates to an apparatus for controlling a compressor, to a method for controlling a compressor and to a refrigerator comprising same. According to certain embodiments of the present invention, a compressor operates selectively in a TRIAC driving mode or in a mode in which commercial power is directly used in accordance with the quality of the electricity of the commercial power. According to certain embodiments of the present invention, the commercial power is directly applied to the compressor within the range of a predetermined voltage or frequency so as to reduce or remove losses caused by the TRIAC driving, and power consumption is reduced to improve energy efficiency.
