Abstract:
1. An apparatus for controlling an operation of a compressor, comprising: a voltage detector for detecting a voltage of an alternating current power applied to the compressor; a triac electrically connected to the compressor; and a controller for generating a switching control signal to control a turn-on duration of the triac depending on the voltage detected by the voltage detector and a predetermined reference voltage value, and outputting the generated switching control signal to the triac, wherein the controller generates a first switching control signal for shortening the turn-on duration of the triac and outputs the generated first switching control signal to the triac, when the detected voltage value is greater than the predetermined reference voltage value; and the controller generates a second switching control signal for lengthening the turn-on duration of the triac and outputs the generated second switching control signal to the triac, when the detected voltage value is smaller than the predetermined reference voltage value.
