ABSTRACT:
Provided is an apparatus for controlling an operation of a compressor which can always apply a constant voltage to the compressor without noise and a method therefor. The apparatus for controlling the operation of the compressor includes: a triac electrically connected to the compressor; and a controller for controlling a turn-on duration of the triac on the basis of a voltage value of an alternating current power applied to the compressor and a predetermined reference voltage value.
