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.
