Abstract:
1. An apparatus for controlling operation of a compressor, the apparatus comprising: a controller that generates a control signal to select an operation mode of the compressor according to an operation load of the compressor; a compressor motor that includes a main coil and a sub-coil, which is driven in one of a plurality of operation modes according to the control signal, and that compresses a refrigerant in the compressor using a turning force with a uniform number of rotations of the compressor motor while a compression capacity of the compressor is varied according to the selected operation mode; wherein the compressor motor is only rotated in one direction; and a power supply that applies power via a plurality of capacitors, each having a different capacitance, to the sub-coil of the compressor motor according to the control signal.
