Abstract:
A compressor control apparatus, and a refrigerator including the same are provided. The operation of two compressors may be controlled using an alternating current (AC) switch, thereby minimizing a number of components, as well as increasing compressor capacity and enhancing operation efficiency. A plurality of operation modes may be used to correspond to a load or freezing capacity using two compressors, and the two compressors may be operated in a separate or simultaneous manner using a drive including two (AC) switches, thereby simplifying the configuration of the system.
