Abstract
A compressor control apparatus, and a refrigerator including the same are provided. Operation of two compressors may be controlled using one inverter, thereby reducing a number of components, increasing compressor capacity, and enhancing operation efficiency of the system. Commonly used switching elements may be switched at an operating frequency, allowing the simultaneous operation of two compressors, reducing switching losses, and improving the efficiency and stability of the system.
