Abstract
Disclosed is an apparatus and a method for controlling a driving of a reciprocating compressor for a refrigerator using a linear motor, in which a capacitance is varied according to a variation of a driving load, thereby improving a driving efficiency of the compressor. To this end, the apparatus for controlling a driving of a reciprocating compressor for a refrigerator using a linear motor comprises a first capacitor for attenuating an inductance of a coil wound on a motor; a second capacitor connected to the first capacitor in parallel; and a relay connected to the second capacitor in series to be turned on/off; and a microcomputer for outputting a control signal to turn on/off the relay according to the driving load of the refrigerator.
