Abstract
A refrigerator includes a compressor, an input current detector to detect input current of alternating current (AC) power inputted to the refrigerator, a converter to convert the inputted AC power into direct current (DC) power, a capacitor to store the converted DC power, an inverter to output AC power using the converted DC power for driving of the compressor, a DC terminal voltage detector to detect voltage at two terminals of the capacitor, and a compressor microcomputer to control the inverter and to calculate refrigerator power consumption based on the detected input current and the detected DC terminal voltage. The refrigerator enables simplified power consumption calculation.
